I found out this only happens with a particular unusual file format so maybe just a bug in FFMPEG to do with that file format.

[michael-mueller-git]

thank you for the bug report. The problem is that ffmpeg was not able to extract the frame. As a result I had no data to process and the program crashed. As a first fix I added an error message so that the program should not crash anymore 0338e3ce68e4e. When I have time I will try to reproduce the problem. Maybe a ffmpeg parameter is missing to use the video format...

[geogan]

Great thanks. My workaround was to just re-encode the original video to a standard format which did not break FFMPEG.

Hello, I seem to be getting some other failure now... and no idea why... it was working earlier, then I changed a few options in first options window when MFTG runs and now it won't run at all, even when I changed options back to the way they were. Any ideas? EDIT: I restarted entire OpenFunScripter and error went away

[michael-mueller-git]

fix crash due to empty sequence is now available in newer versions and this error should not longer occur. I also fixed an error where the program crashes when it is unable to decode the video #24 .

Please reopen issue if error still exists.

[geogan]

Thanks, I am still having strange random crashing of entire program but not related to this problem. (load existing project/video - it appears, finishes loading, then entire program crashes a few seconds later maybe 50% of time.)

[michael-mueller-git]

Thanks for your feedback. Unfortunately, i don't get much feedback from others about what doesn't work or causes problems. In Addition i don't use my program that often and therefor may not aware of all problems that exists.

If you program crash generates an traceback output in the logfile (as with your previously posted log). It would be helpful if you could just post it here or in a new issue. Then I can perhaps find out what the problem might be...
