[Libva] Driver stuck on picture encode

[Lionel Landwerlin]

Hi,

Playing around with the h264 encoder on Haswell, I've noticed that I can 
get the encoder stuck in gen75_mfc_avc_encode_picture() essentially by 
setting a bitrate above with can be generated by the encoder for a given 
picture.

Should the driver just give up at some point?
Do you think an upper bound of what a frame size might be could be 
computed so that the driver doesn't manage to reach that size, it will 
fail rather than being stuck?

Thanks,
