jpeg2000: unsupported marker 0xFF5F at pos 0x73
See fdfcde74_excerpt_000000-000023 (on ftp://upload.ffmpeg.org/MPlayer/incoming/ as suggested by ffplay). The dir contains a MXF (DCI specs) with 24 4K frames and a 1/4-sized proxy video of that segment. The source MXF is real-world and currently in distribution. It was apparently generated with a Clipster system and asdcp-info says http://pastebin.com/raw.php?i=FFnHrW6K about it. ffplay (3e0c78b as of today) says http://pastebin.com/raw.php?i=df5sJDth when trying to play the excerpt MXF and fails to generate frames -- essentially the same as for the source MXF. Yes, the console output is that garbled. Wolfgang

Thank you for the sample, you can use -vcodec libopenjpeg if you need to decode it with FFmpeg. Carl Eugen

http://pastebin.com/raw.php?i=M9PpNFui It does produce frames, though.

Should I rather setup a ticket for this instead of spamming the list? Wolfgang

I suspect this is ticket #2586, should be tested again once that is fixed. Carl Eugen

Perfect, thanks. And sorry, I should have searched the tracker. Wolfgang
Hi Wolfgang, The native jpeg2000 decoder doe not support yet 4k frames. so until that problem is fixed, is better to use libopenjpeg. cheers Nicolas Le 28/09/2013 07:58, Wolfgang Woehl a écrit :

The 40kb mxf file decodes bit-exact now with current FFmpeg (compared to libopenjpeg), all 24 frames are entirely black.

The h264 file you also uploaded looks visually different though... Thank you for the sample! Carl Eugen
