5729bbfdc7 avformat/nutenc: Do not pass NULL to memcmp() in get_needed_flags() 
This compared to the other suggestions is cleaner and easier to understand
keeping the condition in the if() simple.

This affects alot of fate tests.

214556b9d9 avcodec/g2meet: Check if adjusted pixel was on the stack 
This basically checks if a pixel that was coded with prediction
and residual could have been stored using a previous case.
This avoids basically a string of 0 symbols stored in less than
50 bytes to hit a O(n²) codepath.
