[02:18:30 CEST] <ncouloute> Since I cant get the concat muxer to output a cfr for mp4. I'm looking into using the concat filter, but is there any way to find out where the files start and end after they have been concatenated?
[02:23:12 CEST] <TheAMM> ffprobe the files before doing the encode, add the durations
[02:23:43 CEST] <TheAMM> file 1 starts at 0, file 2 starts at file_1_duration
[02:24:10 CEST] <TheAMM> probably + one frame
[02:27:56 CEST] <ncouloute> problem is I'm changing the framerate of the files as well.
[02:30:08 CEST] <JEEB> I'd probably just stick the video/audio streams together separately and then apply the stream copy frame rate patch so -r XX would work
[03:28:32 CEST] <ncouloute> Not sure I understand what all that means.I think you mean combine the video stream together as one file and combine the audio together as one file and then custom build ffmpeg with a patch located somewhere.. Currently using zeranoe build. Where would I find this patch? Cant be too hard
[03:55:31 CEST] <friendofafriend> ls
[03:55:37 CEST] <friendofafriend> Excuse me.
[04:10:33 CEST] <obscure> can ffmpeg trim bits out of a 250 mb webm video
[07:43:21 CEST] <__raven__> processing images to video clips sometimes leads to an endless loop caused by "invalid data found..." due to negative duration. how to exit that?
[23:43:32 CEST] <FreeBDSM> hello
[23:44:57 CEST] <FreeBDSM> it looks like I'm having problems with ffmpeg being unable to play a file: `ffprobe -show_streams 'file:that_file.mp4'` results into `Unsupported codec with id 32797 for input stream 0`
[23:46:50 CEST] <TikityTik> can you reference subtitle streams? -filter_complex "[0:v]subtitles=[0:s]"
[23:51:53 CEST] <furq> TikityTik: -i foo.mkv -vf subtitles=foo.mkv
[23:52:08 CEST] <TikityTik> furq: sometimes the filenames are too long
[23:52:20 CEST] <TikityTik> which is why i was wondering if i could do it through those stream identifies
[23:52:51 CEST] <furq> yeah you can't use labels like that
[23:56:09 CEST] <FreeBDSM> tech is crap :(
[23:56:16 CEST] <FreeBDSM> nothing just works
[23:57:04 CEST] <TikityTik> lol
[23:58:35 CEST] <TikityTik> ah got it working
[23:58:48 CEST] <TikityTik> err nevermind
