[07:36] <highgod> Hi all.Does anyone familar with openvideo?I want to add it to ffmpeg.I reference dxva2 code to get the parameters of openvideo from ffmpeg,and use it as a input to openvideo.the I frames and P frames has been decoded correct.but B frames didn't.I don't know why.has anyone ever use it before?

[09:46] <ubitux> j-b: you still have the rtmpdump on windows?
[09:46] <ubitux> you confirm me that "./rtmpdump -v -r "rtmp://cp73422.live.edgefcs.net/live/eTF1-Flash-Live@8976/eTF1-Flash-Live@8976" -W "http://www.wat.tv/images/v40/PlayerWat.swf?revision=4.0.69" -o - | ./ffmpeg -i - -f null -" with latest rtmpdump & ffmpeg fails?
[09:47] <ubitux> (rtmpdump +bug)
[09:48] <j-b> this week-end
[09:49] <ubitux> http://estcequecestbientotleweekend.fr :(
[10:05] <ubitux> http://easyhtml5video.com  the video in presentation has the Lavf signature, if someone on windows could check... it looks like they might be violating the license
[10:08] <ubitux> (i don't have a windows or mac os at hand)
[10:11] <juanmabc> just curious, what part of the license, sell?
[10:11] <ubitux> i'm not a lawyer, but iirc they have to at least mention they use it
[10:12] <ubitux> i'm just pointing that out, since it looks suspicious to me
[10:12] <nevcairiel> does anyone even care anymore?
[10:12] <nevcairiel> even the hall of shame is gone
[10:13] <ubitux> setup is here http://easyhtml5video.com/download/winnwove09348
[10:15] <ubitux> ok they indeed distribute avcodec-53, avformat-53, eavutil-51 and swscale-2
[10:16] <nevcairiel> now figure out if its ffmpeg or libav =P
[10:16] <ubitux> :)
[10:20] <ubitux> lol ffmpeg.exe
[10:20] <highgod> Hi,all.Where can I download the newest develop code?not the release code ?thanks
[10:20] <ubitux> FFmpeg configured with --enable-gpl
[10:20] <nevcairiel> highgod: http://git.videolan.org/?p=ffmpeg.git
[10:21] <highgod> nevcairiel:oh,thanks
[10:22] <highgod> I want to merge our code to ffmpeg code and continue to do some work.we will submit our code later
[10:30] Action: juanmabc hopes it is an amv-codec-tools guy
[10:30] <juanmabc> :D
[10:41] <fj> Anyone have a book recommendation about video engineering for a noob
[10:45] <fj> I want to become a digital video engineer and help development on ffmpeg
[10:45] <juanmabc> read some code
[10:48] <fj> The code doesn't explain basic concepts about video
[10:51] <JEEB> http://www.xiph.org/video/vid1.shtml
[10:51] <JEEB> basic concepts? have fun
[10:54] <fj> thanks : )
[13:40] <japjap> Hello
[13:40] <japjap> Is it possible to receive RTP packets via UDP and have ffmpeg convert them into MP4 on the fly ?
[13:41] <japjap> Would piping UDP data to stdout and have ffmpeg process stdin work ?
[13:43] <ubitux> fj: i like http://lurkertech.com/lg/video-systems/ as well
[13:44] <ubitux> there are a few other related guides
[13:47] <Compn> japjap : as long as ffmpeg can understand rtp over udp it can mux it to mp4...
[14:07] <japjap> Compn, can it understand RTP over UDP ?
[14:10] <kierank> yes
[14:28] <japjap> +kierank, could you please tell me how should I run ffmpeg in order to listen to UDP and do the conversion of input to MP4 ?
[14:28] <kierank> read the docs
[14:28] <kierank> i have no idea
[14:29] <japjap> ffmpeg -i udp://localhost:8844 -map 0:0 -map 0:1 -s 640x360 -vcodec libx264 -g 60 -vb 500000 -strict experimental -vf yadif -acodec aac -ab 96000 -ac 2 -y -f segment -segment_time 60 "xxx-%03d.ts"
[14:29] <japjap> but that did not work
[14:48] <michaelni> japjap, if you have a sdp file you use this as input, if you have raw udp (NOT rtp over udp) you can use something like udp://127.0.0.1?localport=8844
[15:13] <burek> guys, does ffmpeg have any legal team or something (a person) that can chase ffmpeg's license abuse from some commercial apps?
[15:18] <Compn> burek : bbb has contacts with the sflc 
[15:18] <Compn> which has been handling ffmpeg stuff for a while
[15:20] <michaelni> burek, Compn -> saste is the official contact for ffmpeg and sflc/spi
[15:20] <Compn> oh ok :)
[15:20] <burek> would it be wise to offer people, on the website, to report projects that are not respecting the ffmpeg's license in exchange for some % of the court settlement or something
[15:20] <Compn> better ask sflc about that , but i think they use any settlement to protect gpl, not pay off whistleblowers
[15:21] <Compn> i like the idea , however :)
[15:21] <burek> I just thought it might bring some more "donations" to the project :)
[15:21] <burek> and help develop things and motivate people more
[15:22] <Compn> burek : last i heard ffmtech had $40k from settlements...
[15:22] <Compn> but i could be wrong
[15:22] <burek> it's really depressive when people work and develop something awesome just to see that some other projects are using it as a starting point to make $
[15:22] <Compn> michaelni knows more than me on most of this :)
[15:22] <burek> well, that's what I'm talking about :)
[15:22] Action: michaelni knows 0 about ffmtech post fork
[15:23] <burek> that might be the way to get the team like vlc has
[15:23] <iive> isn't ffmtech overtaken by libav fork?
[15:23] <Compn> i think reimar is on ffmtech board 
[15:23] <Compn> ;P
[15:23] <Compn> and stefano possibly
[15:24] <iive> yes, but the majority is libav people. so they decide.
[15:24] <iive> also, the election should be held each year, I must have missed the announcement.
[15:26] <michaelni> IIRC stefano resigned from the ffmtech board, iam not sure reimar still is on it
[15:30] <michaelni> iive, ffmtech election rules are made by ffmtech (and thats run by libav)
[15:33] <cbsrobot> "burek: and help develop things and motivate people more" ... see http://www.youtube.com/watch?v=u6XAPnuFjJc
[15:33] <Compn> burek : so, to clarify, ignore ffmtech, and focus on the ffmpeg spi account :)
[15:51] <burek> cbsrobot, cool video :) I agree with it :)
[15:51] <burek> but, if you have more money to buy more servers for example for fate testing
[15:52] <burek> it would help, right? :)

[18:26] <burek> do I understand the concept of ffmpeg/ffserver correctly? is it true that ffmpeg communicates with ffserver through a HTTP query and gets all the <streams> information, contained in ffserver's config file, and based on that info it creates new threads (using various -vcodec, -acodec, etc) for each <stream> item?
[18:27] <burek> I mean, if I have ffmpeg on one machine and ffserver on another machine, which machine will experience high cpu usage if I start ffmpeg with: ffmpeg -i bla.avi http://machine2:port/feed1.ffm
[18:28] <burek> shortly, does ffmpeg do the encoding thing, requested by user's <stream> items or is it an ffserver's job?
