hi, My last patch added read support, now this on adds write support for reel names in tcmd atoms, as documented here:
https://developer.apple.com/library/mac/documentation/quicktime/qtff/QTFFChap3/qtff3.html/apple_ref/doc/uid/TP40000939-CH205-57409#//apple_ref/doc/uid/TP40000939-CH205-69831 The docs refer to this as "Source reference" but I used the metadata key "reel_name" because thats what FFmbc calls it. This might also help address ticket#3753. I tried to keep the patch very minimal. Currently, the reel name is only written if both timecode and the metadata are added to a specific stream. example usage: ffmpeg -f lavfi -i testsrc -t 1 -timecode 01:00:00:00 -metadata:s:v:0 reel_name=ABCD123 OUTPUT.mov ffprobe OUTPUT.mov Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'out.mov': Metadata: major_brand : qt minor_version : 512 compatible_brands: qt encoder : Lavf55.52.100 Duration: 00:00:01.00, start: 0.000000, bitrate: 399 kb/s Stream #0:0(eng): Video: mpeg4 (Simple Profile) (mp4v / 0x7634706D), yuv420p, 320x240 [SAR 1:1 DAR 4:3], 387 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default) Metadata: handler_name : DataHandler encoder : Lavc55.73.101 mpeg4 timecode : 01:00:00:00 Stream #0:1(eng): Data: none (tmcd / 0x64636D74), 0 kb/s Metadata: handler_name : DataHandler reel_name : ABCD123 timecode : 01:00:00:00 Mark Reid (1): write reel_name metadata to tmcd atom libavformat/movenc.c | 25 +++++++++++++++++++++++-- 1 file changed, 23 insertions(+), 2 deletions(-) -- 2.0.0 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
