Error with VCEEnc while encoding via FastFlix

[Seenthe]

Source and command line (aka arguments).
If source is too large, try to crop fragment that fails to encode, if possible.

You also can try debug mode to log whatever error AMF produced.

And mandatory question is:
"Had you tried to do it directly with VCEEnc?"
Because if you did and it still crashed, then it is VCEEnc issue and FastFlix has nothing to do with it, and vice versa.

Although it's unsure about the detailed of the situation with limited information here, VCEEnc 8.36 refines hw decode API call procedure, which might be able to fix this issue. (Actually this type of problem is basically difficult to fix without the actual input file to reproduce the issue)

If the problem not fixes, the exact command line and information and input file might help.
