Comment:

 After spending about 20 hours troubleshooting, there appears to be 2
 problems here:
 1, PTS errors: "Starting new cluster due to timestamp" when memory usage
 reaches 8 GB at approximately 1:12.
 2, Memory leak: "Error while filtering: Cannot allocate memory" when
 memory usage exceeds 120 GB at 18:46.32.
 Disclaimer: I don't know for sure, but PTS errors & memory leak are my
 best guesses.

 First things, first: Fix PTS errors.

 I would attach 00000.1.MKV (84,480,629 bytes) & 00000.1.LOG (76,586 bytes)
 but there's a 2.5 MB limit. Granted that 00000.1.MKV is not 00000.m2ts,
 but maybe it would help.
