b50767c31d vf_pad: keep a reference to the output buffer.
Once fixed, the end_frame function does exactly what
avfilter_default_end_frame does; therefore, end_frame
can be removed to let avfilter_default_end_frame work.

Fixes ticket #1038.

83f15a1228 avs: fix infinite loop on end-of-stream.
The codec would keep returning the last decoded frame if the stream
contains B-frames, since it wouldn't clear that frame from the list of
frames to be returned to the user.

8c7721e709 mxfdec: Fix Avid AirSpeed files being misinterpreted as OP1a
The "ECs != 1 -> OP1a" assumption was wrong. Luckily, the file that triggered
that behavior had two ECs, not zero. Hence distinguishing between them is
simple in this case.

6eda85e15b sbrdsp.asm: convert all instructions to float/SSE ones.
Since the values are floats, using the float operations
makes sense, improves performance on some CPUs and
makes the code SSE compatible instead of needing SSE2.

Based on suggestion by Jason.

There is only one caller, which does not need the shifting. Other use cases
are situations where different roundings would be needed.
