If not the only the only way I can think of to test this is to hack ffmpeg to remap the planes in libopenjpegdec.c (e.g., remap them to yuva format). You can use that for initial validation but it'll have to be reverted when committing/pushing. Long-term I'm not sure how one would regression test this without having a different file with a sane pixel format. I'm not sure how feasible it is to hack p1_03.j2k to remove a plane while retaining the ppm marker or perhaps hacking opj_compress to add a ppm marker to a new test file. _______________________________________________ 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".
