[00:03] <EhevuTov> Anyone know if the PPM codec has changed with 'image2pipe'? my old command doesn't work 'gource -1280x720 --stop-at-end --key --hide filenames -s 1 -a 2 -c 2.5 -o - | ffmpeg -y -b:v 10000K -r 60 -threads 4 -f image2pipe -vcodec ppm -i - -vcodec libx264 ~/Desktop/teknoAdminSNMP.x264.mp4'
[00:07] <EhevuTov> Here's my error message. If someone who knows error messages, particularly with image2pipe, I'd really appreciate it: http://pastebin.com/Dp2wpSM0
[00:22] <yano> while ffmpeg is processing a conversion, what does the 'q' mean? is that the compression rate?
[00:25] <saste> EhevuTov: try the latter version, i recently changed ffmpeg to give more hints in that case
[00:25] <saste> my guess is that you need to specify video size or pixel format to ffmpeg
[00:25] <EhevuTov> saste, thank you for looking at it, but I'm not sure what you mean. I'm using what I believe is the latest version
[00:26] <saste> EhevuTov: no it's the latest release
[00:26] <saste> but again try to specify -video_size and -pixel_format
[00:26] <EhevuTov> ok
[00:26] <saste> -pix_fmt
[00:26] <EhevuTov> ok, thank you so much. I'm not sure what the format is though :-P
[00:27] <EhevuTov> saste, does it mean, like .gif or jpeg?
[00:29] <saste> EhevuTov: tried your command and works fine here
[00:29] <saste> try the latest git version, that may help
[00:29] <EhevuTov> yeah, I'm using what is the latest in my Mac home-brew ports system
[00:30] <saste> check the wiki for compilation instruction on your platform of choice
[00:31] <saste> http://ffmpeg.org/trac/ffmpeg/wiki/MacOSXCompilationGuide
[00:31] <EhevuTov> saste, I checked the port's git for this build and nothing major changed. it's interestingly not working
[00:31] <EhevuTov> thank you for the links, I appreciate it
[00:31] <saste> EhevuTov: pastebin?
[00:32] <EhevuTov> what would you like to see? I already submitted one pastebin
[00:32] <saste> i mean with latest git, that's ffmpeg 11.1, latest release
[00:32] <EhevuTov> yeah, let me check what I've got
[00:32] <EhevuTov> 11.1 here
[00:33] <EhevuTov> runs fine, just has issues with the image2pipe parameteres
[00:33] <EhevuTov> guess I need more info on the 'image2pipe' params
[00:34] <saste> EhevuTov: "latest release" is not "latest git", i can't reproduce your problem with my version
[00:34] <EhevuTov> oh right
[00:34] <EhevuTov> I thought you said 11.1 worked
[00:35] <saste> in latest git you should get more info in case of failure at least , i know because i did the change for logging more info
[00:38] <EhevuTov> saste, awesome, thanks. I'm cloning the repo now.
[00:52] <EhevuTov> saste, here's my new error msg's with the latest git: http://pastebin.com/k4LhXXCG
[00:53] <EhevuTov> it looks like I need some new parameters. Do you know where I could find information on these parameters?
[00:53] <saste> that's weird...
[00:53] <saste> well at least it is saying what's missing, -video_size
[00:54] <saste> try to specify -video_size 1280x720  before -i
[00:55] <EhevuTov> 'Could not find codec parameters for stream 0 (Video: ppm, 1280x720): unspecified pixel format'
[00:55] <EhevuTov> it's like the 'ppm
[00:55] <EhevuTov> it's like the 'ppm' isn't being recognized
[00:56] <EhevuTov> I take that back, 'ppm' is being recognized to some extent at least. When I enter 'foo' instead of 'ppm' it says Unkown Decoder: 'foo'
[00:57] <yano> is there a setting to have ffmpeg use whatever bitrate/quality to get it to convert a video to a specific file size?
[00:59] <Mavrik> EhevuTov: isn't the error "unspecified pixel format" clear enough? You need to specify pixel format in which ppm image will be saved.
[00:59] <saste> EhevuTov:   Reason: image not found
[00:59] <Mavrik> yano: sadly no, you'll have to calculate bitrate manually :\
[01:00] <saste> that's suspect
[01:00] <saste> i'd say maybe it's a problem of gource
[01:00] <EhevuTov> Mavrik, but I'm piping to make it into a vid
[01:00] <Mavrik> EhevuTov: and?
[01:00] <saste> ppm should contain the pix_fmt/video size info, so no need to specify it to ffmpeg
[01:00] <yano> dang, hm
[01:00] <saste> so my guess is that it's a problem of gource...
[01:00] <yano> but when i set a bitrate ffmpeg doesn't always use it
[01:00] <EhevuTov> saste, right, it's almost like gource isn't outputting correctly to have image2pipe determine
[01:01] <yano> it fluctuates as it's converting the video
[01:01] <Mavrik> ppm doesn't carry pixel formatinformation
[01:01] <EhevuTov> that's what I thought
[01:01] <Mavrik> only width/height
[01:01] <Mavrik> yano: yeah, that's expected and normal :)
[01:01] <EhevuTov> which is why I don't understand that error
[01:01] <yano> huh
[01:01] <Mavrik> there's no such thing as CBR video encoding for most formats :)
[01:01] <yano> but i'm trying to make an flv that is CBR
[01:02] <yano> from an avi
[01:02] <EhevuTov> ok, well thank you for helping me saste. I'll look into what gource is doing
[01:02] <EhevuTov> I guess I'll push the ppm's to the drive first and then see if ffmpeg will read them
[01:03] <saste> EhevuTov: try also with -pix_fmt yuv420p (the default value if i guess correctly), i think the problem is in gource, since it is working perfectly here
[01:03] <Mavrik> EhevuTov: try forcing "-s 1280x720 -pix_fmt" first (and make sure it's passed before -i)
[01:03] <EhevuTov> oh, ok great. I appreciate that since I have no clue about ppm format
[01:04] <EhevuTov> ok
[01:05] <Mavrik> yano: you can force constant bitrate with minrate, maxrate parameters
[01:05] <Mavrik> the result will probably look very bad though
[01:06] <EhevuTov> saste, Mavrik, ok, it forced it just fine and even opened a pipe to the decoder, but nothing was getting there it seems
[01:06] <EhevuTov> so it does seem like a prob with gource not outputting to the pipe
[01:06] <yano> Mavrik: i've been doing that, but it doesn't seem the output during the conversion is staying the same as what i specify
[01:07] <EhevuTov> thanks for the heads up on he explicit parameters. I had no clue myself
[01:07] <yano> maybe it's because i don't understand what the -bufsize should be?
[01:07] <yano> i want the bitrate to be 1250kb/s
[01:07] <Mavrik> time for
[01:07] <yano> so i set -minrate, -maxrate and -b to 1250k
[01:07] <yano> ah, hm, ok, one moment
[01:09] <Mavrik> (any reason why do you NEED EXACTLY 1250k?)
[01:10] <yano> Mavrik: http://www.pastebay.net/1070292
[01:10] <yano> the original idea behind using 1250k was to make a comparison to a windows program which was doing a conversion at 1250k
[01:10] <yano> and at 30fps
[01:11] <Mavrik> hrm
[01:11] <Mavrik> yeah, you're confusing the heck out of the encoder
[01:11] <yano> but i'm at the point where i don't really care about the bitrate anymore, i just want the output filesize to be 80% of the original with the best possible quality
[01:11] <yano> yea
[01:11] <Mavrik> the underflow/overflow  errors
[01:11] <yano> i figured i don't understand what i'm really doing on the cli, since i've been pulling in bits and pieces from various sites and the manpage
[01:11] <Mavrik> your input bitrate seems to be 500kb/s
[01:12] <Mavrik> which explains why encoder refuses to magically create data for 1250kb/s output :)
[01:12] <yano> ah
[01:12] <yano> that explains it
[01:13] <Mavrik> that's also confirmed by encoding output - encoder is making video at around ~600kb/s and can't go higher
[01:13] <EhevuTov> saste, ok, I found the root cause. Gource was missing a link ref to one of it's libs that 'home-brew' didn't take care of. I understand the ffmpeg errors better now. Thanks!
[01:13] <Mavrik> also you're trying to create a 1250kb/s mp3 track :)
[01:13] <yano> eek
[01:13] <Mavrik> which is... well... overdoing it :D
[01:13] <yano> yea...
[01:14] <Mavrik> yano: so if you want ~480 kb/s stream (which is 80% of your input)
[01:14] <Mavrik> you should do something like
[01:15] <Mavrik> ffmpeg -i PV30101.avi -vcodec flv -s 640x480 -r 30 -maxrate 480k -acodec libmp3lame -ab 64k -ar 22050 -f flv PV301-AW.flv
[01:15] <Mavrik> (there might be some errors in that, you're using avconv instead of ffmpeg :) )
[01:16] <Mavrik> there's a "-b 400k" missing after "-vcodec flv"
[01:16] <yano> ah, i was using ffmpeg, then it keep saying it was deprecated, so i aliases ffmpeg to avcon
[01:16] <Mavrik> yeah, that's Ubuntu/Debian maintainer f*up
[01:17] <Mavrik> anyway, I'm off to sleep, g'luck :)
[01:18] <yano> ah
[01:19] <yano> darn, using that command i get, "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height"
[02:27] <dicroce> Does anyone know where there is an sample code that uses libavformat to containerize a series of frames? (I.E. not transcoding, and not encoding)
[09:55] <jessy> hey there, i just configured ffmpeg as like http://pastebin.com/Tqz3JXMv, but while compiling x11grab i'm getting tons of errors , is there any idea ?
[09:55] <jessy> here is the error log ; http://pastebin.com/fanhcCYN
[09:58] <spaam> jessy: what kind of errors?
[09:59] <spaam> ah
[09:59] <jessy> spaam: there is error log http://pastebin.com/fanhcCYN
[09:59] <jessy> if i don't enable-x11grab everything is fine
[10:33] <eftekhari> is timeshift working on ffserver?
[10:44] <eftekhari> how to get timeshift working on ffserver? ??
[11:10] <jessy> hey there i'm trying to compile ffmpeg with 'x11grab' but i'm getting tons of errors, here is the configuration : http://pastebin.com/Tqz3JXMv and here is the error log : http://pastebin.com/fanhcCYN is there any idea ? 64 bit debian
[11:41] <ubitux> jessy: something really looks broken on your side
[11:41] <jessy> ubitux: yeah badly stuck with that issue :/
[11:42] <ubitux> i have a 64 bit debian here, and no issue building with x11grab
[11:42] <jessy> ubitux: i'm sure i installed whole dev packages and linux headers which is my system using but i have n1 more idea in that step :/
[11:43] <jessy> ubitux: is it possible to share that build with me with my configuration ?_?
[11:43] <ubitux> that would be braindead because of non-matching libraries
[11:44] <jessy> ubitux: static build won't be problem as i know
[11:45] <ubitux> i'm not going to make you some static build
[11:45] <jessy> ubitux: which kernel version are you using ?
[11:45] <ubitux> how is that related to the kernel?
[11:45] <ubitux> i'm using 3.2.0
[11:45] <jessy> these builds doesn't have x11grab option
[11:46] <jessy> "how is that related to the kernel?" i have no idea but your bots seperated them with kernel >.>
[11:47] <ubitux> i'm wondering if your header file isn't broken, or if you messed up the code by some mean
[11:47] <belgianguy> hi, I'm planning on using a digital SPDIF audio input stream (96kHz/24-bit), but want to 'fake' the input for now, can I do such thing with ffmpeg?
[11:47] <ubitux> try to debug the problem
[11:47] <ubitux> look at the source.
[11:48] <jessy> ubitux: i didn't change anything on source code, but i'm not sure about my headers :/
[11:48] Action: burek sets mode +apple_juice ubitux
[11:48] <burek> :)
[11:48] <ubitux> hi burek e
[11:50] <burek> belgianguy, why do you want to fake it?
[11:51] <belgianguy> because my laptop lacks the hardware for SPDIF input atm :/
[11:52] <burek> ok, how exactly do you want to fake it
[11:52] <belgianguy> and I'd rather not invest in hw when I'm not sure if this project will take off
[11:52] <belgianguy> I thought about just taking a hq audio file/stream and convert/stream it locally as a 96kHz/24bit linear PCM
[11:53] <belgianguy> but I'm very new to all the terminology, too
[11:53] <burek> well, you can always replace the real live audio input with a wav file
[11:53] <ubitux> you can use aevalsrc to generate some sound
[11:55] <belgianguy> and how do I make sure the wav file matches the stream? I'll have to look up what aevalsrc is, too :)
[11:55] <belgianguy> is SPDIF always WAV then?
[11:57] <burek> well, that was the purpose of my question WHY and HOW do you want to fake it, i.e. what is the use case for that
[11:57] <burek> do you need an audio input with some specific parameters or you need to play with a virtual device and buffers or what
[11:57] <belgianguy> I want detect certain events in an audio stream, as I'm just beginning with audio processing
[11:58] <belgianguy> the idea is that a mixer generates this stream in a RL scenario (eg a Pioneer DJM-800)
[11:58] <burek> you want to implement some sort of audio filter?
[11:58] <belgianguy> and I want the digital out to be input into my machine, and do real-time analysis on it
[11:58] <belgianguy> detecting onsets, bass patterns etc
[11:58] <burek> ok
[11:59] <burek> well, you might take a look at ffmpeg's audio filters
[11:59] <burek> in libavfilter subdir
[12:00] <burek> they all work (I guess) on a raw pcm audio, decoded from various input formats (like wav)
[12:02] <belgianguy> ah, and would I be able to generate the 96kHz/24 bit type of audio with ffmpeg?
[12:02] <burek> sure
[12:02] <burek> just set the appropriate output codec/format
[12:03] <burek> something like: ffmpeg -i input.mp3 -acodec pcm_s24le -f wav out.wav
[12:03] <burek> ffmpeg -i input.mp3 -acodec pcm_s24le -ar 96k -f wav out.wav
[12:04] <burek> type ffmpeg -codecs for the complete list of output codecs
[12:04] <burek> and ffmpeg -formats for output formats
[12:04] <belgianguy> ah, thanks, I had already found the pcm_s24le mentioned, but wasn't sure if that really did what I needed
[12:04] <burek> (they need to have a flag 'E' set, which means they are encoders and can produce the output)
[12:05] <belgianguy> ah, good to know, thanks!
[12:05] <burek> :beer: :)
[12:07] <belgianguy> any idea if the real stream would have headers (?) that identify it as WAV, or whether it would be raw?
[12:08] <burek> you can control that too
[12:08] <burek> ffmpeg -i input.mp3 -acodec pcm_s24le -ar 96k -f wav out.wav
[12:08] <burek> note -f wav
[12:08] <burek> defines output format
[12:08] <burek> now, type ffmpeg -formats
[12:08] <burek> and find a raw audio output format
[12:08] <burek> and use it instead of wav
[12:08] <burek> if you need it
[12:09] <belgianguy> ah, yeah I should have looked first
[12:09] <burek> and you can always use a hex editor :)
[12:09] <burek> to check
[12:10] <belgianguy> hmm, there are even some unsigned PCM codecs in 24 bit, bot little endian and big endian
[12:11] <belgianguy> is there a way to find out whether my stream would be signed or unsigned?
[12:12] <burek> :)
[12:13] <burek> well, since you create the output stream, I think you should know if you will create it as signed or unsigned
[12:14] <belgianguy> :) I want to be as close to what the device will ultimately put on the wire
[12:14] <belgianguy> but the manual isn't very helpful
[12:14] <burek> well, you request from the device which format do you want
[12:15] <burek> so choose the format you want (first read the supported formats of the device)
[12:15] <belgianguy> 48kHz/24bit, 96kHz/24bit Linear PCM
[12:15] <belgianguy> that's all it says, it's the digital out of the DJM-800 mixer
[12:15] <burek> you have an example cmd line how to create 96k/24b pcm with ffmpeg
[12:16] <burek> it's just a matter if it is little endian or big endian
[12:16] <burek> what are you capturing the audio with?
[12:16] <burek> alsa?
[12:16] <belgianguy> atm nothing, that's the next step
[12:16] <burek> well, if I was to do that, I would use the ffmpeg's libs to do all the work
[12:17] <burek> because they have implemented alsa input
[12:17] <burek> various outputs
[12:17] <burek> and all I would need to create is a custom audio filter I need
[12:18] <burek> so, I could type something like: ffmpeg -f alsa -ar 96k -i hw:0 -af "myfilter=myparams" -f wav output.wav
[12:19] <burek> or to pipe it to the next audio output if you want live filtering
[12:19] <burek> anyway, you get the point
[12:20] <belgianguy> yeah, it's becoming clear how I would have to approach it
[12:20] <belgianguy> the examples help a lot
[12:23] <belgianguy> the live filtering part, would that be simulating a streaming input?
[12:23] <belgianguy> eg not having access to the whole audio, but just whatever appears on the line
[12:30] <jessy> ubitux: i switched to kernel 3.2x it compiles fine
[13:31] <raph12> Hi guys, which variable in my ffmpeg command line I have to look at to make FLV seekable from the flash player ?
[13:48] <TwisteR> Hello! Can someone help me? I need to render .ass subtitles (to add an telemetry information to the video captured by remote manipulator)
[13:48] <TwisteR> I'm using opensuse and ffmpeg -filters 2>&1 | grep "libass" shows nothing...
[13:48] <JEEB> I think the filter name was ass?
[13:49] <TwisteR> Does that mean that I need to recompile ffmpeg to add libass support?
[13:49] <JEEB> if neither is there, then yes
[13:49] <JEEB> also you could check the ffmpeg configuration line that IIRC comes out at every start of the binary
[13:49] <JEEB> if it has no --enable-libass or similar
[13:49] <TwisteR> I have libass installed on my system, can ffmpeg use it as external library (like mplayer)?
[13:50] <JEEB> yeah
[13:50] <TwisteR> yep, there is no libass in the configuration line
[13:50] <JEEB> yup, then you'd have to compile your own
[13:50] <JEEB> git HEAD is recommended in most cases
[13:51] <TwisteR> [14:50:06] <TwisteR> I have libass installed on my system, can ffmpeg use it as external library (like mplayer)?
[13:51] <TwisteR> [14:50:11] <JEEB> yeah
[13:51] <TwisteR> is that was the answer to my question? :-)
[13:51] <JEEB> yes
[13:52] <TwisteR> but nevertheless I need to recompile ffmpeg?
[13:52] <JEEB> naturally
[13:52] <TwisteR> ok, thank you!
[13:53] <TwisteR> what a pity that there is no my favorite Gentoo at the work... :)
[13:54] <TwisteR> USE="libass"...
[13:55] <raph12> Hi guys, I need a bit of help to make my flv seekable when encoding from ffmpeg, which variable should I look at?
[13:55] <TwisteR> and since there is no gentoo, I need to install tons of -dev packages, which I need to figure out by hand
[13:57] <JEEB> TwisteR, not much. What are you using?
[13:57] <JEEB> as pretty much all decoders are in libavcodec
[13:58] <JEEB> you mostly need separate libraries for screen capture/encoding
[13:58] <JEEB> and you should pretty surely know what you're going to encode :)
[13:58] <JEEB> (and even then it's just small parts of the encoders available)
[13:59] <JEEB> compiler + yasm + bash or something similar is already enough to get most of ffmpeg built
[14:38] <TwisteR> JEEB: can you tell, please, how to get the ffplay binary to be compiled? I have only ffserver, ffprobe and ffmpeg
[14:39] <JEEB> check after installing SDL -dev
[14:40] <TwisteR> thanks
[15:14] <raph12> Hi guys, I need a bit of help to make my flv seekable when encoding from ffmpeg, which variable should I look at?
[16:20] <jessy> hey there, i'm trying to capture my desktop with 5fps, "ffmpeg -f alsa -i pulse -f x11grab -r 5 -y -s 1920x1080 -i :0.0 -acodec libmp3lame -vcodec libx264 -threads 0 ~/Desktop/test.avi" with that command i have problem with audio input audio is ending middle of video , any idea ?
[16:20] <jessy> i guess i was using -isync parameter in windows with that parameter it was working well, but i couldn't figured out in linux
[16:26] <raph12> if I knew I would help :/
[16:27] <raph12> For me I'm stuck with flv that are not seekable, you know anything about this subject?
[17:32] <finga> i want to program a tool for mixing videos is there something going on with ffmpeg ?
[17:33] <Hydrant> hey all, for some reason while doing a screen capture the colors are wrong (e.g. green becomes pink)... anyone come across this before?  Here is the command used: ffmpeg -f x11grab -r 25 -s 1280x720 -i :0.0+0,24 -vcodec libx264 -vpre lossless_ultrafast -threads 0 video.mkv
[18:51] <hypnocat> how can i direct ffplay to output audio to jack?
[19:14] <Helgoland> Cheerio guys, my libmp3lame version >= 3.98.3  is not found when cross-compiling, but is found when i compile for linux... how's that possible?
[21:14] <TadekMocarz> HELLO
[21:14] <TadekMocarz> anybody there
[21:15] <TadekMocarz> the ffmpeg is not working. it dosent convert to any format i choose
[21:15] <TadekMocarz> but video is playing with ffplay
[21:15] <TadekMocarz> i tried all formats, none worked
[21:15] <TadekMocarz> garbage
[21:15] <TadekMocarz> for example i tried:

[21:19] <teratorn> TadekMocarz: dont use shitty windows software :(
[21:19] <TadekMocarz> windows great, just winff weak
[21:19] <TadekMocarz> in linux you propably dont even have gui..
[21:19] <TadekMocarz> you just enter some magic keywords and commands
[21:19] <TadekMocarz> i want to use mouse, not keyboard
[21:20] <microchip_> TadekMocarz: real men don't need no stinking GUI! :P
[21:21] <TadekMocarz> i will check those videos in sansa clip zip
[21:21] <TadekMocarz> what is the good  kb/s  for 96x72 pixels
[21:21] <TadekMocarz> ?
[21:22] <TadekMocarz> i want high quality
[21:26] <TadekMocarz> i did used windows gui software for wget
[21:26] <TadekMocarz> but its shitty too
[21:26] <TadekMocarz> but console's even shittier
[21:37] <llogan> TadekMocarz: i thought the sansa clip zip was only a music player
[21:46] <TadekMocarz> noo
[21:46] <TadekMocarz> llogan, if u put Rockbox software
[21:46] <TadekMocarz> u can watch videos, play gameboy color games
[21:46] <TadekMocarz> just everything
[21:46] <TadekMocarz> there is even Doom game
[21:47] <TadekMocarz> 3d game
[21:47] <TadekMocarz> www.rockbox.org u better check this
[21:50] <llogan> wow, packard bell made a player?
[21:50] <llogan> it should come as a 6-pack since they would probably be disposable
[22:04] <TadekMocarz> WHAT DOES -r paramater doing ?
[22:05] <TadekMocarz> i checked the video on sansa and  its too much cpu extensive
[22:05] <TadekMocarz> need to make it easier for cpu
[22:05] <sacarasc> Sets the frame rate.
[22:06] <TadekMocarz> thats good idea
[22:06] <llogan> TadekMocarz: what video formats can the device decode?
[22:30] <TadekMocarz> hi again i got disconnected
[22:30] <TadekMocarz> i need help with formatting video
[22:30] <TadekMocarz> i use -f mpegts -acodec libmp3lame -b:a 96k -ar 32000 -vcodec mpeg1video -vf scale=96:72 -b:v 104k -r 8 -strict -1
[22:31] <TadekMocarz> but the resulting video requires too much cpu
[22:31] <TadekMocarz> any tips ?
[22:31] <TadekMocarz> how can i make it uncompressed avi ?
[22:32] <sacarasc> TadekMocarz: Rockbox sucks for video.
[22:34] <TadekMocarz> sucks or not sucks.. its software decode on 25Mhz cpu
[22:34] <TadekMocarz> cant expect much
[22:34] <TadekMocarz> but i want to atleast smooth play on some format
[22:35] <sacarasc> I tried mpeg1 on my iPod 5.5, but it couldn't do it with rockbox.
[22:35] <TadekMocarz> maybe too big resolution and too big bitrate?
[22:37] <TadekMocarz> http://www.rockbox.org/wiki/PluginMpegplayer#Performance
[22:40] <TadekMocarz> is there an option to choose between size and peformance?
[22:40] <TadekMocarz> i dont care about big file size
[22:42] <TadekMocarz> is there a way to convert stereo audio to mono
[22:50] <TadekMocarz> help plax
[23:19] <llogan> TadekMocarz: "-ac 1" is one method
[23:19] <TadekMocarz> thanks
[23:20] <TadekMocarz> but now i am trying to convert them in Sony Vegas
[23:20] <TadekMocarz> i has GUI
[23:20] <TadekMocarz> and i can set advanced paramters like I-FRAMES
[23:20] <TadekMocarz> etc
[23:23] <llogan> we can't help you here with Vegas
[23:24] <TadekMocarz> nevermind.. vegas dont allow me to set fps lower than 23
[23:24] <TadekMocarz> so will try again in ffmpeg
[23:25] <TadekMocarz> can somebody explain me this:
[23:25] <TadekMocarz> frame=   53 fps=0.0 q=2.0 size=     155kB time=00:00:04.21 bitrate= 300.7kbits/s
[23:26] <TadekMocarz> im interested in q variable
[23:26] <TadekMocarz> higher = higher quality and more cpu-extensive ?
[23:26] <TadekMocarz> i want to set this parameter manually
[23:26] <TadekMocarz> how to
[23:27] <TadekMocarz> how to choose between mpeg2 levels and profiles
