I see, the problem are the CAVLC contexts that are derived from neighboring macroblocks. If the macroblock cannot be decoded, we will get wrong contexts.

I think your solution works for simple cases, but can be improved: mb_nr-1 is not always the left macroblock, e.g. at the left border. With FMO the left MB might be coded in a different slice - for which the DP is available. I think, I will try some more advanced error indication.

Let me know if you like to test my code before the next release.
