27209bb108 h264: mark some MC functions with av_always_inline instead of inline. 
This actually causes them to be inlined, leading to a significant

14c21c1ff5 H264: Only wait before triggering ff_thread_setup_complete() until the next slice that contains a start-of-field/frame macroblock 
This allows concurrent decoding of the last field/frame, rather than
only the last slice, of data packets with multiple NAL units packed
together.

This will fix the slowdown reported in e.g. bug 52.

5cc2600964 dsputil: create 16/32-bit dctcoef versions of some functions 
High bitdepth H.264 needs 32-bit transform coefficients, whereas
dnxhd does not.  This creates a conflict with the templated
functions operating on DCTELEM data.  This patch adds a field
allowing the caller to choose the element size in dsputil_init()
and adds the required functions.

aa15e68721 Fix decoding of mpegts streams with h264 video that does *NOT* have b frames 
One of the causes of this bug is that the h264 parser defaults low_delay
to 1, but the h264 codec defaults low_delay to 0. Really Ugly.

After many hours of looking at this, I'm still not sure how has_b_frames
is *intended* to behave, but to me the implementation appears way more
complicated than it ought to be.

My patch relies on the encoder to set an optional field in the SPS. This
works for libx264 streams, but I'm not sure that all h264 encoders will
set it.

4e987f8282 h264: correct border check. 
When backing up the top-left border, check that the top-left
(rather than left) MB indeed does belong to our slice. If it
doesn't, backing up has no positive effect but may accidentally
interfere with other threads writing in the same space.
