It does not matter the input: If FFmpeg crashes, there is a serious
issue, as said, it can (normally) be either fixed if it can be
reproduced (I cannot reproduce it but I may miss something since
I have not seen console output when it crashes without -vcodec
libx264) or if a backtrace is provided. Please understand that I
am not asking you to recompile FFmpeg, I am simply explaining why
the crash is unlikely to get fixed atm.

Why aren't you using -probesize?
Without, I also get a delay (actually, I suspect I get a delay,
I never waited long enough).

I believe it actually is not correct (= there is A/V desync when
you play the stream with ffplay), but because of the nature of the
streams, you don't (easily) see it.
