KongQun Yang 9a55d4033f Adjust timestamps in mp4 if there is an initial composition offset
In some ISO-BMFF files, there is an initial non-zero composition offset,
but there is no EditList present.

This is against ISO-BMFF spec recommentation [1] and we believe in most
cases it is just missing the EditList.

[1] 14496-12:2015 8.6.6.1
It is recommended that such an edit be used to establish a presentation
time of 0 for the first presented sample, when composition offsets are
used.

Issue: #112.
Fixes: b/110782437.

KongQun Yang 9ecee46658 Fix SAMPLE-AES EC3 encryption
The IV was incorrectly updated across samples.

Created a new cryptor SampleAesEc3Cryptor specially for SAMPLE-AES
EC3 encryption / decryption. The new cryptor uses constant-iv, and
makes sure the IV is reset to the initial value at the beginning
of each audio frame and chained across syncframes within the the
audio frame.

Also added E-AC3 end to end test.

Fixes #279

KongQun Yang 068e220ac7 Handle additional unused 'mdat' properly
The spec allows having more than one 'mdat' boxes even if it is not
used.

This is happening on some mp4 files in the wild:

Fixes #298.

Kongqun Yang e5b6096857 Generate tkhd and pasp boxes properly with non-square pixels
- Width/Height in tkhd box should be display resolution instead of
  coded resolution.
- pasp was not generated earlier.
- Assuming SAR as 1:1 if it failed to be extracted successfully.
- Also update test files for mp4_media_parser_unittest.

This fixes Issue #35.
