I don't know if there are more significant issues, but the first errors are pretty serious:
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f0fb0000c80] STSC entry 4 is invalid (first=4 count=19 id=1)
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f0fb0000c80] STSC entry 3 is invalid (first=3 count=18 id=1)
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f0fb0000c80] STSC entry 2 is invalid (first=2 count=19 id=1)

A dump makes it clear the stsc is broken:
<SampleToChunkBox Size="2164" Type="stsc" Version="0" Flags="0" Specification="p12" Container="stbl" EntryCount="179">
<SampleToChunkEntry FirstChunk="1" SamplesPerChunk="27" SampleDescriptionIndex="1"/>
<SampleToChunkEntry FirstChunk="2" SamplesPerChunk="19" SampleDescriptionIndex="1"/>
<SampleToChunkEntry FirstChunk="2" SamplesPerChunk="19" SampleDescriptionIndex="1"/>
<SampleToChunkEntry FirstChunk="3" SamplesPerChunk="18" SampleDescriptionIndex="1"/>

The second entry is repeated twice.
Never seen that before, very specific... Here it seems clear that the entry is doubled and the second one can be ignored, of course, but really this is not a clean patch nor a safe hack to support that kind of corrupted files in a general manner.
BTW, be careful with corrupted files 'supported' by some systems one day; they may not be supported another day.
