With this change, no default flags are used. It seems that when a sample
has to use the default flags, in Safari, it can cause problems with MSS.
With HLS this does not happen.
Fixes https://github.com/shaka-project/shaka-player/issues/7509
This change removes `concat` util function from mp4 generator iterations
and runs it later, as well as stops creating new Uint8 arrays, as
`concat` does this within itself.
This prevent errors when the codec specified is not the same that in the
stream, and also fixes the override when there are multiples codecs (eg:
muxed content)
- Allow to have multiple transmuxers, but choose only the one that is
valid depending on whether it supports the codecs or not
- Supported codecs: AAC, AC-3, EC-3, H.264, MPEG/MP3
- It is prepared to allow more codecs in the future (HEVC/H.265) (no
muxed)
