[FFmpeg-user] How to create a multichannel wav file without a specific channel layout

Hi, I would like to know if it is possible to create a wave file that contains n channels of audio which do not have a channel layout like 5.1 or stereo, much like a file used in broadcast for just storing n signals in one wav file. Thanks for any hints on this, Robert

[FFmpeg-user] Find out supported pixel formats for a codec

Hi, is there a systematic way to find out supported pixel formats for a codec (or filter) on the command line? I only found ffmpeg -pix_fmts but that is the global list of all known pixel formats. Thanks, Robert ___ ffmpeg-user mailing list ffmpeg

Re: [FFmpeg-user] Enable all audio tracks for MOV container

using the patch myself (thanks for the patch, btw.), just asking the obvious question. Was this discussed as a patch and rejected? At least having it as a muxer or command line option seems to be a better solution than not having it at all in master as there are obviously use cases for it out there.

Re: [FFmpeg-user] Accurate Trimming Without Transcoding

I'm not suggesting to throw away the frames. Keep the frames but set an appropriate start time. That way the "trimmed" frames would be decoded but not displayed. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpe

[FFmpeg-user] Accurate Trimming Without Transcoding

Is it possible to achieve frame accurate trimming of clips without transcoding? e.g. if I have a 50 fps file with a fixed gop of 50 frames and I'd like to trim the first 24 frames without transcoding. Shouldn't ffmpeg simply generate a remuxed file with a startTime of 0.48s and a duration adjusted

Re: [FFmpeg-user] No duration with pipe:1 as output

[FFmpeg-user] No duration with pipe:1 as output

When I set "pipe:1" as the output the resulting file always ends up without a duration in it's metadata/header (ffprobe doesn't find it). I'm primarily interested in outputting webm, but I have the same issues with nut and mkv. Is there a way around this? _
