3816642eab dsputil_mmx: Surround QPEL macros by "do { } while (0);" blocks. 
This makes them safe to use in non-fully braced if-blocks and similar.

68893afe1d movenc: Merge if statements 
This isn't exactly equivalent with the earlier code for codecs
other than H264 and VC1, but those are two only codecs supported
by this codepath anyway, and it simplifies it a bit.

147ee4cf06 pthread: Immediately release all frames in ff_thread_flush() 
Before this, they were only added to the delayed release queue and not
freed until later. This could lead to unnecessary memory use or buffer
exhaustion.

14ba7472dc vp8: fix update_lf_deltas in libavcodec/vp8.c 
lf_delta.ref[i] and lf_delta.mode[i] were incorrectly reset to 0 if
specific delta value was not updated. Fixed to keep the previous value
if flag indicates that element in question is not updated.

494bce6224 ralf: read Huffman code lengths without GetBitContext 
Those descriptions are stored in nibbles, so they are easy to extract.
And this way we don't need to pad tables for possible bit reader overreads.

73ad4471a4 rv34: Handle only complete frames in frame-mt. 
Correct handling of errors to prevent hags or crashes is very complex
otherwise.

The frame initializing is also moved from decode_slice() to
decode_frame() for clarity.
