Hi, The following patch adds support for detecting more dnxhr header prefixes.
After generating many random resolution dnxhr files via quicktime, I have deduced that second 4 bytes in prefix is the header size or data offset to the end of the scan table. On heights smaller then 1080 the header size is always 0x0280 here are some samples with prefixes that aren't currently supported. https://dl.dropboxusercontent.com/u/170952/ffmpeg_samples/new_header_prefixs/lb_2k_2048x1536.mxf https://dl.dropboxusercontent.com/u/170952/ffmpeg_samples/new_header_prefixs/lb_4k_Full_Aperture_4096x3112.mxf https://dl.dropboxusercontent.com/u/170952/ffmpeg_samples/new_header_prefixs/lb_custom_2766x3234.mov https://dl.dropboxusercontent.com/u/170952/ffmpeg_samples/new_header_prefixs/lb_custom_3462x2134.mov Mark Reid (1): libavcodec/dnxhd: add support more dnxhr header prefixes libavcodec/dnxhddata.h | 15 +++++++++++---- libavcodec/dnxhddec.c | 2 +- 2 files changed, 12 insertions(+), 5 deletions(-) -- 2.7.3 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
