[00:04:44 CEST] <c_14> from the first input, yes
[00:04:50 CEST] <c_14> you can limit what it takes
[00:07:21 CEST] <Prelude2004c> but the transort stream had 5 programs
[00:07:57 CEST] <Prelude2004c> i want to relay them all > another destination without altering them
[00:08:14 CEST] <c_14> yeeeeees?
[00:08:48 CEST] <Prelude2004c> i will try -map 0 .. crashed server though so can only try tomorrow
[08:40:47 CEST] <NxtLevel> Hello all, I have a problem with capturing from IP camera RTSP stream to a jpeg image
[08:41:28 CEST] <NxtLevel> http://pastebin.com/txLJBrCG
[10:02:32 CEST] <dharriso> Hi, I have a question conserning the use of the libav* libs in an appliaction.  Is this the correct IRC channel?
[10:03:08 CEST] <__jack__> sure
[10:11:43 CEST] <dharriso> So I have an MP4 file that has 5 tracks, 1 Audio, Video and 2 hints tracks. I create a variant of this file at a lower bitrate with only 2 trakcs and audio and video file, no hint tracks, this works fine, Problem is when I seek to a video keyframe, seeks request for each track, however the seek on the hint track is not what i expect
[10:12:51 CEST] <dharriso> its at a time of 3.xx seconds not at the 1.xx of the keyrame time
[10:14:16 CEST] <dharriso> not sure why this is, can you explain.
[10:14:44 CEST] <dharriso> Additionally is there a way of tell the API to ignore the hint tracks, just consume the data but dont call back to the application
[10:24:36 CEST] <jookiyaya> what is hints tracks?
[10:27:31 CEST] <dharriso> a hint track is used to include streaming information in the file for example RTP type formats
[10:27:45 CEST] <dharriso> its not needed by me but its a track in the original MP4 file
[10:49:43 CEST] <t4nkGuide> hello everyone...
[10:50:47 CEST] <t4nkGuide> im trying to make a vid from jpg files, but it give me an error [swscaler @ 0x2e87960] deprecated pixel format used, make sure you did set range correctly?? why that happening
[10:52:21 CEST] <t4nkGuide> i resize my various jpg with mogrify to same resolution.
[10:54:16 CEST] <t4nkGuide> oh yeah. ignore ratio resize.
[14:06:28 CEST] <xace> is ffmpeg able to capture the screen with libx264 using vdpau as pixel format?
[14:07:33 CEST] <iive> this doesn't make sense. ffmpeg is able to capture screen and encode it with libx264
[14:09:10 CEST] <xace> When i dont specify a -pix_fmt it prints: "No pixel format specified, yuv444p for H.264 encoding chosen. Use -pix_fmt yuv420p for compatibility with outdated media players."
[14:15:41 CEST] <retarder> hello anybody know how to use avconv to save streams to different output files simultaneously?
[14:16:40 CEST] <retarder> i need to split video and audio without discarding any, while capturing v4l2 input stream
[14:17:08 CEST] <retarder> i don't want to create a muxed container (avi, mpeg, ...)
[14:17:48 CEST] <retarder> i need to edit video and audio separately
[14:27:44 CEST] <BtbN> avconv is not ffmpeg
[14:27:46 CEST] <xace> Currently when I capture the screen, the capturing process with libx264 works fine, however later when I run the result in the mediaplayer, it complains about being unable to use hardware decoding, does anyone know of a method to capture the screen fast but which also produces a video file capable of hardwareacceleration?
[14:49:42 CEST] <retarder> ok i found out a way with -map directive
[14:50:39 CEST] <retarder> -map 0:v:0 -y /path/to/video.mpeg -map 1:a:0 -y /path/to/audio.pcm
[15:37:33 CEST] <synthecypher> How can I get ffmpeg to remove the ffmpeg2pass-0.log file after it's finished?
[16:02:55 CEST] <c_14> synthecypher: you have to remove it manually or by doing something like appending && rm ffmpeg2pass-0.log to the 2nd pass encode
[17:13:21 CEST] <Julius1241> hello all
[17:13:37 CEST] <Julius1241> any gurus with RTSP/ ipcams around
[18:10:37 CEST] <proctrap> hey there, could be an odd question, but is there an "--newline" param, so I'm not gettinga \r for the status updates ?
[18:11:06 CEST] <proctrap> (I could also use TR, but that's very cpu intense & I would like to avoid replacing \r with \n.. )
[18:18:22 CEST] <fling> What is the modern way of recoding my lossless and nearly lossless videos? I have a lot of spare cpu times and I want to get small sized files.
[18:18:40 CEST] <fling> I also need to shift audio for a bit
[18:38:13 CEST] <fling> How to create multiangle video?
[18:48:37 CEST] <fluffrabbit> what is up, my socially awkward friends?
[18:49:13 CEST] <fluffrabbit> Is this the right channel to complain?
[19:20:21 CEST] <Julius1241> guys i need some help with RSTP and ip cam
