Fair enough. I would like to keep all the info such as size, pixel format, etc. (as its still useful information), so I'll use AV_CODEC_ID_NONE so it's ignored. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".

You could change the demuxer you submitted to simply skip the video track and demux only the audio, which afaik can be decoded by libavcodec. If this Argo video codec was supported by some other container then it would make sense adding a descriptor for it, as it would allow remuxing. But as is, it's probably better not to bother with it. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".

If I leave it at AV_CODEC_ID_NONE, then the ffmpeg CLI complains with "Could not find codec parameters". I don't want to set it to AVMEDIA_TYPE_UNKNOWN because then you lose all the codec parameters. I would like to add a decoder eventually, but I'd have to reverse engineer it. There's also not many samples to work with, so I'm not sure how viable it'd be. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".

If there is no actual video decoder source code ever
going to be added then no point in adding this.
