Details

When running mochitest with rust MP4 preference on, sample count in dom/media/test/gizmo-short.mp4 is different comparing to stagefright.

Total sample count is 12 but only 11 samples in 'stsc' table; the last sample should be in the final chunk.

<SampleToChunkBox EntryCount="6">
<BoxInfo Size="88" Type="stsc"/>
<FullBoxInfo Version="0" Flags="0x0"/>
