Comment (by peter_b): @Gyan: I'm surprised to hear that, because from a quick look at [https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/isom.c libavformat/isom.c], I thought that the static codes-table is deprecated and replaced by ISO639-2 stored in 3*5 bits ASCII (as written in [https://developer.apple.com/library/archive/documentation/QuickTime/QTFF/QTFFChap4/qtff4.html#//apple_ref/doc/uid/TP40000939-CH206-35103 MOV-specs]): /* map numeric codes from mdhd atom to ISO 639 */ /* cf. QTFileFormat.pdf p253, qtff.pdf p205 */ /* http://developer.apple.com/documentation/mac/Text/Text-368.html */ /* deprecated by putting the code as 3*5 bits ASCII */ -- Ticket URL: <https://trac.ffmpeg.org/ticket/6103#comment:6> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
