@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 */
