I see in log that x264 file transforms from 720x406 to 720x416 (Reinit context to 720x416) while original ffv1 file for stays unchanged. Can this be the reason of SIGSEV and how to check it?

backtrace from unoptimized ffmpeg:

  • Keywords crash added
  • Priority changed from normal to important

Does valgrind show something useful?

  • Keywords SIGSEGV added
  • Reproduced by developer set
  • Status changed from new to open

Not a regression, also reproducible with shorter files (attached).
