This should be what you need. The output AVStream doesn't have a discrete type like raw content does (e.g. where you have audio/video/data). The content of the packets is driven entirely by the codec ID. > But if it's defined like this, it will output a video with eia_608 > type.... which doesn't t allow ccaption_dec to be applied. The output is defined by the codec. If your encoder takes in video AVFrames, throws away the actual video content, and uses the side data to output packets with the codec AV_CODEC_ID_EIA_608, that should be perfectly fine. > If it's defined like: > > .type = AVMEDIA_TYPE_SUBTITLE, > > .id = AV_CODEC_ID_EIA_608, > > No video packets will be sent to it. Right, that definitely won't work, because the ffmpeg core won't deliver video AVFrames to it. Did you actually try what you specified in the first scheme? That should work fine, so if you tried it and it didn't I would be interested in seeing the errors you got. Devin -- Devin J.
