History
rohks ecb0024a0b Improve frame rate calculation by using media duration from mdhd box 
- Added logic to parse media duration from the `mdhd` box for accurate frame rate calculation.
- Fallbacks to track duration from `tkhd` when `mdhd` contains invalid or missing data.
- Avoids incorrect frame rate calculations in MP4 files with an edit list (`elst`) box.
- Adds frame rate calculations for partially fragmented MP4 files.
- Verified accuracy with tools like `mediainfo` and `ffprobe`.

Issue: androidx/media#1531

**Note**: The slight difference in frame rate values in dump files that aren’t MP4s with an edit list or fragmented MP4s isn’t due to differences in `tkhd` and `mdhd` duration values (which should be identical for non-edited or non-fragmented files). Rather, it’s because they are calculated using different timescales. The `mvhd` box defines a global movie timescale, which is used for the track's `tkhd` duration. Meanwhile, each track’s `mdhd` box defines its own timescale specific to its content type, which we now use for more accurate frame rate calculation.

Muxer dump files

To generate a new dump file or to update an existing one:

  1. Change DumpFileAsserts#DUMP_FILE_ACTION to WRITE_TO_LOCAL (for Robolectric tests) or WRITE_TO_DEVICE (for Instrumentation tests).
  2. Re-run the test.
  3. Change DumpFileAsserts#DUMP_FILE_ACTION back to COMPARE_WITH_EXISTING.
