Segmentation fault
I had first tried the same command with "-threads 6", and it
printed the following before crashing:
ffmpeg: malloc.c:4631: _int_malloc: Assertion `(unsigned long)(size) >=
(unsigned long)(nb)' failed.
Aborted
Then I tried the one above, in case it was a multi-threading issue,
but that doesn't appear to be the case.
The input .mkv file is 1.1GB; I can upload it somewhere upon request.
