Using the Jan 27, 2016 64-bit Windows build from Zeranoe, ffmpeg crashes after encoding with dirac. It runs through the entire thing and produces an unplayable output file with a correct looking file size, but crashes at the very end with a Windows crash dialog.

ffmpeg -i input.avi -vcodec dirac -f avi output.avi

Report and output of Windows crash dialog attached.

Note that the Windows crash dialog can't identify the module and may only be marginally useful.

  • Component changed from ffmpeg to undetermined
  • Resolution set to needs_more_info
  • Status changed from new to closed

Without a backtrace, I don't think there is anything a developer can do. Please report your issue in the Zeranoe forum. Note that the output file you attached plays fine here.

I will post it there. If and when I can get a stack trace from a debug build I will post it here.

I am actually able to play the file as well. VLC can't (that's all I had tried), but Windows Media Player w/ the K-Lite codecs can. So it does appear to generate the file correctly at least.
