When extracting AC3 track and saving it to mp4, the wrong type of ac-3
packet is included in MOOV.
packet header in stsd in MOOV set to 'AC-3' instead of 'ac-3'
Section 5.6.1.1.2 of
http://uvcentral.com/sites/default/files/files/PublicSpecs/CFFMediaFormat-
2_1.pdf
ffmpeg -i test.mpg -map a -c copy ac3.mp4
ac4.mp4 HEX offset 1227D-12280: "AC-3"
ffmpeg -i test.mpg -map a -c copy ac3.ac3
ffmpeg -i ac3.ac3 -c copy 2step.mp4
2step.mp4 HEX offset 1227D-12280: "ac-3"
How can ac-3 be set properly in MP4's MOOV packets when extracting AC3
track from MPG to MP4 please?
