Comment (by Gyan):

 As per the ffmpeg log, ffmpeg was killed abruptly, which prevented ffmpeg
 from flushing out the moov box to the output file. When ffmpeg directly
 receives a single SIGINT, it will print at the end `Exiting normally,
 received signal 2.`. I suspect the SIGINT is received by yt-dl which does
 not relay it to ffmpeg but kills it, in which case, ffmpeg won't wait for
 the output trailer to be written. But this is a guess.
