As you probably know, there can be quite a lot of work in producing such a test case.

Recent comments on this list suggest strongly to me that information about behavioural anomalies in ffmpeg are not particularly welcome. I appreciate the issue - it isn't nice to have one's work criticised - but that's part of being a software engineer.

Personally I would be concerned that I would simply be asked for more and more information until we got to something I couldn't provide (I still have only the haziest idea what a "gdb backtrace" is). I think this sort of thing is used as an excuse to ignore the problem. Not everyone is a software engineer (nor should they be) and the development team need to be willing to do some of the legwork themselves. It's part of the job.

Until this changes, you can see why people aren't willing to put the time in.
