If ffmpeg
crashes (as the ticket title suggests), please provide backtrace, disassembly and register dump as explained on https://ffmpeg.org/bugreports.html
If ffmpeg
freezes, run the binary from gdb
, interrupt it with Ctrl-C and post the backtrace here.
In any case, you need (static) ffmpeg_g
, the debug binary.

By freezing I mean server is not working anymore, just help reset button.

Replying to sub.s7v7n:
By freezing I mean server is not working anymore, just help reset button.
This indicates an issue that is not related to FFmpeg.
gdb does not start:
#gdb: unrecognized option '-hwaccel'
That's not how gdb works and this is explained in the link I posted.
