[00:17:44 CET] <hanna> eh I was just interested for the purpose of using this in mpv's vo_gpu
[00:17:52 CET] <JEEB> yea
[00:18:10 CET] <JEEB> as far as I know there's no proper scenechange detection stuff in FFmpeg
[00:18:16 CET] <JEEB> well, as "proper" as such things are
[00:18:33 CET] <JEEB> in the subtitling world what I linked used to be the general level
[00:20:08 CET] <JEEB> hanna: basically you could have seen what sort of algo was used, and then seen during playback when a "scene change" was hit
[00:23:42 CET] <paule32> hello, need help
[00:23:43 CET] <paule32> https://pastebin.com/VhEFjUv8
[00:24:14 CET] <JEEB> paule32: you need to specify the output container
[00:24:38 CET] <JEEB> it can't guess it by the "ffn" extension
[00:28:53 CET] <paule32> JEEB: thx
[00:28:55 CET] <paule32> but
[00:28:57 CET] <paule32> sudo ./ffmpeg -f x11grab -r 5 -s 1024x720 -i :0.0 -preset ultrafast -f mp3  http://localhost:8181/feed1.ffn
[00:29:03 CET] <paule32> give me next errors
[00:29:24 CET] <JEEB> you're trying to put video into mpeg-1 layer 3? :)
[00:29:45 CET] <paule32> ehm, yes
[00:29:48 CET] <paule32> stupid
[00:29:51 CET] <paule32> ffserver
[00:29:59 CET] <paule32> directive?
[00:30:26 CET] <BtbN> ffserver is dead, don't use it
[00:42:44 CET] <paule32> JEEB: https://pastebin.com/c3L3krzC
[00:43:07 CET] <JEEB> still
[00:43:11 CET] <JEEB> you're taking in video, and outputting mp3
[00:43:20 CET] <JEEB> mp3 cannot have any video so it tells you there's no streams
[00:44:32 CET] <paule32> and why do i can watch over the half internet video.mp3 ?
[00:48:10 CET] <c_14> you're probably thinking of mp4
[00:57:01 CET] <paule32> https://pastebin.com/sK0CsnL9
[00:57:14 CET] <paule32> i get other error's, now
[00:57:47 CET] <JEEB> because non-fragmented mp4 doesn't work
[00:57:51 CET] <JEEB> for streaming
[00:58:19 CET] <JEEB> you probably wanto -movflags
[00:58:29 CET] <JEEB> -movflags frag_keyframe
[00:58:34 CET] <JEEB> for fragmented mp4
[00:58:48 CET] <JEEB> but really, if you want to do web streaming then just use nginx-rtmp
[00:59:02 CET] <JEEB> and then feed rtmp to it and you can get HLS/DASH
[01:03:02 CET] <kerio> you can get hls with just ffmpeg too, tho
[01:03:12 CET] <JEEB> sure
[01:03:38 CET] <JEEB> I guess you can even do the shared fragments thing with HLS and DASH now?
[01:03:43 CET] <JEEB> no idea how well it works, though ^^;
[01:04:36 CET] <kerio> lmao dash
[01:04:57 CET] <JEEB> also I should patch the HLS master playlist generator to also take maxrate into mention :P
[01:05:07 CET] <JEEB> currently it requires one to set bit_rate
[01:10:40 CET] <paule32> so, ther server+client run
[01:10:44 CET] <paule32> but
[01:10:46 CET] <paule32> av_interleaved_write_frame(): Broken pipe time=00:00:49.40 bitrate=   0.0kbits/s speed=0.992x
[01:10:46 CET] <paule32> Error writing trailer of http://localhost:8181/feed1.ffm: Broken pipe  0.0kbits/s speed=0.992x
[01:10:57 CET] <JEEB> your server gave up
[01:10:58 CET] <paule32> the error message above
[01:11:09 CET] <paule32> to low memory?
[01:11:29 CET] <paule32> of MaxFileSize=5M
[01:11:32 CET] <paule32> ?
[01:11:36 CET] <JEEB> I have no idea
[01:11:57 CET] <JEEB> if that's ffserver then you will unfortunately not get any support on it here
[01:12:06 CET] <JEEB> it was a long-discussed thing that nobody was maintaining
[01:12:10 CET] <JEEB> so it finally got removed some time ago
[01:12:25 CET] <paule32> ok
[01:12:37 CET] <kerio> put ffmpeg in cgi-bin and use mjpeg
[01:12:39 CET] <kerio> ez
[01:12:41 CET] <JEEB> as I said, if you just want to do streaming that you can point a browser to, nginx-rtmp is probably the way to go (or just plain nginx with file PUTs working with HLS)
[01:13:30 CET] <paule32> then i have to leave apache?
[01:13:42 CET] <kerio> well
[01:13:49 CET] <kerio> i mean
[01:13:51 CET] <JEEB> you can do the HLS post thing with apache too ,sure
[01:13:53 CET] <kerio> it is 2018
[01:14:09 CET] <JEEB> but I bet yhou will get less help with configuring that :)
[01:14:23 CET] <kerio> JEEB: nginx-rtmp doesn't even do hls by itself anyway
[01:14:28 CET] <kerio> it just puts fragments in a directoryt
[01:14:28 CET] <JEEB> it does
[01:14:40 CET] <JEEB> at least the README says it does
[01:14:41 CET] <kerio> and then it's your responsibility to host them
[01:14:46 CET] <kerio> yea sure but
[01:15:07 CET] <JEEB> basically looked at https://github.com/sergey-dryabzhinsky/nginx-rtmp-module/
[01:15:20 CET] <furq> if only nginx-rtmp had some kind of http server
[01:15:22 CET] <furq> but it doesn't
[01:15:31 CET] <kerio> furq: but paule32 wants to use apache
[01:15:33 CET] <kerio> :\
[01:15:41 CET] <kerio> no idea why
[01:15:44 CET] <furq> rip
[01:15:53 CET] <kerio> ikr
[01:16:15 CET] <JEEB> well effectively if it generates the files then just making a webroot for that I think is good enough?
[01:16:25 CET] <JEEB> I don't really see the issue here other than it doesn't have its own buffer format
[01:16:30 CET] <kerio> but anyway, there's nothing simpler in using nginx to host the hls files generated by nginx-rtmp rather than using apache
[01:16:33 CET] <JEEB> from which it generates those things on the fly
[01:16:40 CET] <kerio> other than the fact that nginx is better than apache, that is
[01:16:54 CET] <JEEB> sure
[01:17:14 CET] <kerio> nginx-rtmp is neato
[01:20:08 CET] <BtbN> kerio, nginx-rtmp is still an nginx, so hosting http is kind of what it does anyway.
[01:36:14 CET] <paule32> there is somewhere wrong
[01:36:17 CET] <paule32> https://pastebin.com/cQnAAps8
[01:41:24 CET] <JEEB> whatever you're feeding to broke the write
[01:41:42 CET] <JEEB> I have no idea what you have behind that HTTP end point
[01:42:20 CET] <paule32> desktop stream
[02:34:41 CET] <n0xlf> furq you still around?
[02:43:57 CET] <aphirst> tomorrow i need to fix the audio on some files
[02:44:07 CET] <aphirst> the L audio track is 0.02 s earlier than the R audio track
[02:44:10 CET] <aphirst> and it makes it sound awful
[06:00:38 CET] <stockstandard> Hey everyone, could someone please help me diagnose this issue? Unrecognized option 'max_muxing_queue_size'. Error splitting the argument list: Option not found
[06:01:12 CET] <stockstandard> I am trying to get this script running and getting that error: https://github.com/Collisionc/sickbeard_mp4_automator
[06:01:26 CET] <stockstandard> Not sure which parameter that is coming from though because i dont believe I am passing anything called max_muxing_queue_size
[11:39:31 CET] <gusto> hi
[11:40:03 CET] <gusto> someone an idea why vc2 is so slow? normally I have no problems, but I tried encoding x11grab fullhd 60fps with vc2 and it gives me like 30% of it
[11:41:20 CET] <gusto> libx264 performs much better giving me almost 60 at default settings and CPU utilisation is about 30%
[11:54:33 CET] <atomnuker> no simd
[13:27:49 CET] <paule32> hello, need help
[13:27:50 CET] <paule32> https://pastebin.com/dx4wGyWC
[13:28:20 CET] <paule32> the stream seem to be streamed, but i can't see picture/video in vlc
[13:28:50 CET] <paule32> when i open network stream:  rtp://127.0.0.1:8182/test1.mp4
[13:35:43 CET] <eenp^> notice the SDP output from ffmpeg?
[13:36:06 CET] <eenp^> i.e. for yours, this is it: https://pastebin.com/eFA7dhrU
[13:36:26 CET] <eenp^> paste that into a file, named say, f.sdp
[13:36:43 CET] <eenp^> now, open that .sdp file in vlc - appears to work well
[13:36:49 CET] <eenp^> @paule32
[13:38:43 CET] <eenp^> also, ffplay should be able to view it too: `ffplay -protocol_whitelist file,udp,rtp -i ./f.sdp`
[13:40:32 CET] <paule32> thank you
[13:42:05 CET] <paule32> but
[13:42:24 CET] <paule32> how is ffplay know about the stream?
[13:42:41 CET] <paule32> lets assume, when i have 2 streams/feeds ?
[13:42:45 CET] <eenp^> the .sdp file contains info about where its located, and some other protocol nonsense
[13:42:58 CET] <eenp^> have a gander inside the sdp output
[13:44:27 CET] <paule32> i can see o,c = ip4 127.0.0.1
[13:44:35 CET] <paule32> and port
[13:44:44 CET] <paule32> that's all?
[13:45:52 CET] <eenp^> line 7 specifies the port
[13:46:08 CET] <eenp^> other than that - don't know too much about the protocol
[13:50:28 CET] <paule32> cool
[13:50:32 CET] <paule32> very fast
[13:50:40 CET] <paule32> at 320x200
[13:52:34 CET] <eenp^> sweet
[13:58:02 CET] <eenp^> oh btw - not sure if anyone was here from when I was asking about why ffmpeg couldn't transcode some files (with an error msg of `[ogg @ 0x5564abcbb7e0] Codec not found`)
[13:58:40 CET] <eenp^> turns out the .ogg had a begin of stream and end of stream at the head of the file, which rogg_pagedump dutifully reported
[13:58:56 CET] <eenp^> just ignoring the first 147 bytes or whatever fixed it
[14:02:27 CET] <cableguy> hello team
[14:02:38 CET] <durandal_1707> hello
[14:02:43 CET] <cableguy> how do i loop video to the length of the audio
[14:02:59 CET] <cableguy> i found same question from 5 months ago https://video.stackexchange.com/questions/22301/loop-webm-video-for-the-whole-audio-length and nobody replied
[14:03:19 CET] <durandal_1707> stream-loop
[14:04:57 CET] <cableguy> you mean -stream_loop
[14:10:13 CET] <cableguy> im using this
[14:10:14 CET] <cableguy> ffmpeg -y -loop 1 -r 6 -i 1.jpg -i 1.mp3 -shortest -c:v libx264 -preset ultrafast -tune stillimage -pix_fmt yuv420p -c:a copy video.mp4
[14:10:22 CET] <cableguy> to loop an image to audio
[14:10:31 CET] <durandal_1707> yes
[14:10:40 CET] <cableguy> but it does not work for video instead of image
[14:10:41 CET] <durandal_1707> for images
[14:12:32 CET] <cableguy> which switch do i change
[14:20:50 CET] <paule32> hello
[14:20:58 CET] <paule32> when i start ffmpeg:
[14:21:01 CET] <paule32> sudo ./ffmpeg -f x11grab -r 5 -s 1000x600 -i :0.0 -preset ultrafast -f rtp  rtp://[2a00:c1a0:8502:2800:1000:1000:1000:10]:8182/test1.mp4
[14:21:05 CET] <paule32> i get:
[14:21:23 CET] <paule32> c=IN IP4 2a00:c1a0:8502:2800:1000:1000:1
[14:21:26 CET] <paule32> for sdp
[14:21:36 CET] <paule32> see: IP4
[14:21:46 CET] <JEEB> sounds like a bug in the code that writes out the SDP manifest
[14:21:54 CET] <JEEB> although you'd have to look at the specification for it
[14:21:58 CET] <JEEB> if there even is an IP6
[14:23:03 CET] <paule32> for http host, i have to write (in browser): http://[2a00:c1a0:8502:2800:1000:1000:1]/index.html
[14:35:14 CET] <BtbN> Why do you run ffmpeg as root?
[14:36:43 CET] <artha> hi can anyone tell me if I can change the filter arguments of ffmpeg in runtime?
[14:37:49 CET] <BtbN> some of them, usually very limited, probably not the ones you want to
[14:39:29 CET] <artha> @BtbN, I am trying to to use the equalizer filter with time varying arguments while playing the audio. is it possible/
[14:40:06 CET] <BtbN> which equalizer?
[14:40:27 CET] <BtbN> There seem to be 3
[14:40:39 CET] <artha> ffplay -af "equalizer=f=1000:width_type=h:width=200:g=-10" -i foo.wav
[14:40:50 CET] <artha> this is the command
[14:40:51 CET] <BtbN> no idea which of the 3 equalizers that maps to, hm
[14:41:51 CET] <furq> use mpv?
[14:41:58 CET] <furq> you can definitely change mpv's eq at runtime
[14:42:10 CET] <furq> and also it's an actual media player and not a proof of concept
[14:42:55 CET] <artha> ok I'll try that. thanks
[14:43:19 CET] <BtbN> http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavfilter/af_biquads.c;h=d5c3823e6446ccf52fd0045da5c207d4e6be997c;hb=HEAD#l454 it does support some runtime reconfig
[14:45:07 CET] <artha> @BtbN, great this is what I was actually looking for.
[14:45:35 CET] <BtbN> I'm not 100% sure how to send those commands when using ffmpeg.c. But I think there is some way?
[14:46:10 CET] <BtbN> Also, there are aparently 4 equalizer filters in ffmpeg.
[14:46:51 CET] <artha> maybe I need to create a callback function. check for changed arguments before the buffer is created
[14:47:04 CET] <BtbN> if you are using the API, it's not a problem at all
[14:47:19 CET] <BtbN> there is a function to send those commands
[14:47:39 CET] <furq> you can drop to an interactive prompt to send commands to sendcmd, but i've never been able to figure out how to operate it
[14:47:46 CET] <furq> and also it'll pause the output while you're at the prompt
[14:48:06 CET] <furq> you could also potentially use the zmq filter
[14:49:23 CET] <artha> Yeah. I dont want the audio to pause. And zmq filter?? I will check that out too
[14:49:41 CET] <BtbN> Are you using the ffmpeg cli, or the libav* libraries directly?
[14:51:09 CET] <artha> till now I have been using the cli. But I got nowhere with it. Now I want to try the libavfilter
[14:51:34 CET] <BtbN> yeah, if you're using the API there will be no extra pause
[14:52:00 CET] <BtbN> And if you're using the ffmpeg cli in some "embedded" way in some other application you can also send commands pretty much instantaneously.
[14:52:04 CET] <artha> I am using python. so now I have to bind the lib to be able to use it'
[14:52:12 CET] <BtbN> But to me it sounds like you're better off using the API
[14:53:32 CET] <artha> I guess however instantaneous i send them, there will be an observable pause in the stream wont it??
[14:53:44 CET] <artha> if I use cli
[14:54:15 CET] <BtbN> I doubt it. Will take a few ms at worst
[14:55:56 CET] <artha> can you recommend a good cli for it?
[14:56:34 CET] <BtbN> hm?
[14:56:43 CET] <BtbN> ffmpeg.c is the cli application
[14:57:15 CET] <artha> I meant for python
[14:58:43 CET] <BtbN> I'm not sure what you mean
[15:01:19 CET] <artha> no prob. I will check out the process_command() api and zmq filter furq suggested. thanks for helping out
[15:58:33 CET] <IsntFunny> Is there some quick way to strip out any audio track without encoding the full video?
[15:58:49 CET] <JEEB> yes, just map only video
[15:58:58 CET] <JEEB> -map v
[15:59:07 CET] <IsntFunny> and -c copy?
[15:59:09 CET] <JEEB> this will map all the video track(s) from all inputs
[15:59:15 CET] <JEEB> which usually is one, but yunno
[15:59:27 CET] <BtbN> -c:v copy -an -sn
[15:59:53 CET] <IsntFunny> welp, awesome. thanks :)
[16:00:05 CET] <JEEB> oh, right -an -sn is the other way
[16:04:00 CET] <IsntFunny> damn
[16:04:05 CET] <IsntFunny> now i messed up all of my footage
[16:04:32 CET] <IsntFunny> And i of course have no backup for those
[16:09:31 CET] <IsntFunny> ffmpeg doesn't have some kind of temp dir where i could try to rescue my files?
[16:09:57 CET] <JEEB> no
[16:10:06 CET] <DHE> did you set your input and output as the same file?
[16:10:08 CET] <JEEB> I mean, if you set your output as input then rip
[16:10:24 CET] <IsntFunny> DHE yep
[16:10:35 CET] <IsntFunny> All my drone footage gone :D
[16:10:55 CET] <DHE> nothing on other media, like the drone itself maybe?
[16:12:44 CET] <IsntFunny> nope, i always move instead of copy. A lot of data and just 64gb of sd card... Even for backups it'd be kind of big. Aw snap
[16:13:13 CET] <IsntFunny> Well, lesson learned
[17:01:46 CET] <Fyr> guys, is there a way to optimize matroska container besides -reserve_index_space?
[17:02:24 CET] <Fyr> mkclean produces smaller files than FFMPEG.
[17:03:21 CET] <Fyr> it means the authors know something.
[17:03:27 CET] <Fyr> (=
[17:03:38 CET] <durandal_1707> by how much?
[17:04:09 CET] <Fyr> not so much
[17:05:25 CET] <Fyr> but the thing about index space should be optimized, like in MP4 files. for now I have to mux it, then remux it, since I don't know how much space is required to write the index.
[17:05:46 CET] <Fyr> then muxing into MP4, FFMPEG mux it and remuxes it automagically.
[17:06:18 CET] <Fyr> ='(
[17:06:54 CET] <durandal_1707> open feature request?
[17:07:14 CET] <next1> close
[17:08:58 CET] <classssic> hi, somebody know  how to decoder h264 to MJPEG using vaapi hw accel?
[17:10:41 CET] <atomnuker> jkqxz has a patch but he's waiting on durandal_1707's patches
[17:11:51 CET] <durandal_1707> how so? look im volunter
[17:18:51 CET] <atomnuker> the yuvj removal
[17:19:03 CET] <atomnuker> cmon, you said its all fixed
[17:19:17 CET] <atomnuker> just resubmit
[17:33:06 CET] <stockstandard> Hey everyone, could someone please help me diagnose this issue? I'm Not sure which parameter that is coming from because i dont believe I am passing anything called max_muxing_queue_size
[17:33:10 CET] <stockstandard> Unrecognized option 'max_muxing_queue_size'. Error splitting the argument list: Option not found. I am trying to get this script running and getting that error: https://github.com/Collisionc/sickbeard_mp4_automator
[17:36:11 CET] <sfan5> https://github.com/Collisionc/sickbeard_mp4_automator/blob/master/mkvtomp4.py#L831
[17:36:22 CET] <sfan5> application devs fault
[17:42:08 CET] <stockstandard> SFAM5 what exactly is the issue?
[17:43:13 CET] <stockstandard> sfan5*
[17:43:40 CET] <sfan5> the application developer is making the assumption that the used ffmpeg version supports -max_muxing_queue_size
[17:43:57 CET] <sfan5> this assumption isn't holding, which is why you're getting that error
[17:44:35 CET] <stockstandard> is that a newer option or something that has been depricated?
[17:45:31 CET] <sfan5> former
[17:45:43 CET] <stockstandard> Right now I am just using 'apt-get ffmpeg' in my docker create, is there a version i should be passing?
[17:46:00 CET] <sfan5> debian-based distributions often ship outdated ffmpeg versions
[17:46:25 CET] <sfan5> if you read the README of that repo, the author suggests downloading ffmpeg from https://ffmpeg.zeranoe.com/builds/
[17:46:34 CET] <furq> that'll work well on linux
[17:46:49 CET] <furq> stockstandard: https://www.johnvansickle.com/ffmpeg/
[17:47:18 CET] <furq> with that said debian stable has 3.2.10 and testing has 3.4.1
[17:47:40 CET] <furq> which should be new enough
[17:48:20 CET] <stockstandard> yeah i just checked, apt-get is pulling version 2.8.11
[17:48:30 CET] <furq> is that ubuntu 16 or something
[17:48:31 CET] <stockstandard> ubuntu
[17:48:33 CET] <furq> right
[17:48:36 CET] <furq> get a newer distro
[17:48:45 CET] <furq> or just use those static builds
[17:50:32 CET] <stockstandard_> Is there a way to reference the newer version in the dockerfile?
[17:50:34 CET] <stockstandard_> https://pastebin.com/BC1waExt
[17:52:01 CET] <sfan5> extract it to /usr/local or something
[17:55:03 CET] <stockstandard_> apologies sfan5 - I am fairly new to all of this... any examples you could show on how to do that
[17:56:48 CET] <sfan5> tar -xf ffmpeg-release-64bit-static.tar.xz -C /usr/local/bin --strip-components=1 ffmpeg-3.4.1-64bit-static/ffmpeg
[17:58:31 CET] <stockstandard_> like this? https://pastebin.com/MZwgGShR
[17:59:59 CET] <sfan5> you'd need to download the file first, but yes
[18:02:34 CET] <stockstandard_> Is there a way to do that in the dockerfile? I have a separate cron job that re-flashes the docker image every week so ideally there would be no manual downloading involved
[18:03:22 CET] <sfan5> ...just invoke wget
[19:12:28 CET] <whytho> Hi! I'm trying to use the ffmpeg libs in a project but I am running into problems. Basically what I'm trying to do at this point is to be able to play both video and audio from the same file. So far I can play video, that is not a problem. Playing the audio of the file at the sime time though, I just can't get it to work.
[19:12:58 CET] <whytho> I've looked at drangers tutorial but it's outdated, I've looked at lei xiaohua's tutorials but all of them seem to be audio or video, not audio and video. I also found a github repo that claims to be working for ffmpeg >=3.2.4 but same there, no sound is playing
[19:13:49 CET] <paule32> hello
[19:14:12 CET] <paule32> my samsung smartphone can't open stream.sdp in chrome browser
[19:14:17 CET] <whytho> What I'm asking here is, can anyone point me in the direction of a guide that shows how to play video and audio from the same video file for ffmpeg 3.4? Preferably using SDL2, but hopefully I can manage that last bit by myself worst comes to worst
[19:14:20 CET] <paule32> what can i do?
[19:14:24 CET] <whytho> I'm using windows 10 BTW
[19:17:09 CET] <JEEB> whytho: the proof-of-concept ffplay thing uses SDL2
[19:17:18 CET] <JEEB> so you could say it's an "example"
[19:23:04 CET] <whytho> I will check that out, thank you!
[19:25:42 CET] <ans_ashkan> Hi all, I'm trying to overlay a sequence of images on top of a video and loop images. this is what I use (ffmpeg  -i hq26368874313361335.mp4 -i "Seq\seq_%5d.png" -filter_complex "[1:v]loop=-1:size=496[top];[0:v][top]overlay=shortest=1"  temp.ts)
[19:26:33 CET] <ans_ashkan> the problem is loop starts at about frame 400 at second loop
[19:27:27 CET] <ans_ashkan> any idea what is wrong with this?
[19:36:53 CET] <kepstin> ans_ashkan: probably a framerate mismatch, you should specify the "-framerate" input option on the png input to the same as the framerate of the video
[19:37:02 CET] <kepstin> if you don't specify, it's 25fps, iirc.
[19:39:15 CET] <paule32> hi JEEB
[19:39:21 CET] <paule32> have you a idea?
[19:42:58 CET] <ans_ashkan> kepstin: video's framerate is 25 too, so they match.
[23:13:05 CET] <paule32> hello, need help
[23:13:07 CET] <paule32> https://pastebin.com/5nPnG5ir
[23:13:27 CET] <paule32> i would like stream webm or mp3
[23:13:38 CET] <paule32> firefox does not support mp4
[23:13:43 CET] <paule32> that the problem
[23:13:53 CET] <paule32> but i think mp3 does support
[23:14:49 CET] <notashark> is it normal for ffmpeg to mangle variable values without assignment?
[23:15:17 CET] <paule32> me?
[23:15:52 CET] <notashark> anyone
[23:16:12 CET] <notashark> paule32: I can't help, sorry.
[23:16:16 CET] <paule32> "-video_size" is the same as "-s
[23:16:45 CET] <paule32> notashark: what do you stream?
[23:17:00 CET] <notashark> I don't stream anything?
[23:17:18 CET] <paule32> transcode?
[23:18:22 CET] <notashark> my use of ffmpeg is just basic conversion; like, wav to flac. I don't use any of the really complicated parts
[23:18:38 CET] <paule32> ok
[23:24:28 CET] <furq> notashark: i don't know what you're actually asking
[23:33:10 CET] <notashark> furq: i have a short (~30loc) script to batch process files. commenting out the ffmpeg line lots the file names get printed just fine. if I uncomment ffmpeg, they are mangled; this is before and after ffmpeg is called
[23:33:25 CET] <notashark> I can only think it's the way the shell is parsing it before even running it, but idk
[23:33:38 CET] <furq> probably some kind of quoting nightmare
[23:33:41 CET] <furq> but pastebin the script anyway
[23:38:46 CET] <notashark> https://transfer.sh/kg04F/ffmpeg.sh
[23:58:48 CET] <sfan5> doesn't ${TRACK/\.original/} make use of a bash-only feature?
[23:58:51 CET] <sfan5> since you're using /bin/sh
