Quoting Anton Khirnov (2024-09-13 12:44:55)Note that -view_ids is a decoder option and does nothing with streamcopy. Also, that option is intended for API users, with ffmpeg CLI you should be using view specifiers instead.Thanks! Tried with "-map 0:v:view:all" and the result is the same. The resulting elementary stream cannot be decoded by ffmpeg as the stream is not conformant.
Are you talking about decoding the resulting raw bitstream created from doing stream copy from the source mov? If so, what's happening is probably that the parser is splitting AUs when the second SEI with layer_id == 0 shows up in those non-conformant samples. This doesn't happen if you try to decode directly from the mov as the parser does not attempt to do any packetization then.
Use view specifiers to split the views into their own streams. I do not want too much multiview-speficic logic into ffmpeg CLI, as it is a rather obscure feature.But the "-map 0:v:view:all" option is still available to output both views as a single stream with alternating views, no? Using "-map 0:v:vidx:0 -f rawvideo out0.yuv420p -map 0:v:vidx:1 -f rawvideo out1.yuv420p" to split the views into separate streams seems to work fine without the issues mentioned before. _______________________________________________ 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".
