b8cac1e830 vaapi_h265: Fix buffering parameters 
A decoder may need this to be set correctly to output frames in the
right order.

fc30a90898 vaapi_h265: Fix slice header writing 
This was not observed earlier because the only syntax element which
it normally misses with the current setup is slice_qp_delta, but that
is always going to be zero (in IDR frames QP isn't varied on the
slice) which will always exp-golomb code as a single 1 bit.  The
immediately following part is the byte alignment, which is always a 1
bit followed by 0s which are ignored, so as long as the bitstream is
never aligned at that point we will never notice because the only
difference is that an ignored bit is a 1 instead of a 0.

314b421dd8 vaapi_encode: Decide on GOP setup before initialising sequence parameters 
This was always too late; several fields related to it have been incorrectly
zero since the encoder was added.

27085d1b47 avconv: only retry decoding on actual decoding errors 
Errors during decoding are currently considered non-fatal and do not
terminate transcoding, so even if parts of the data are corrupted, the
rest may be decodable.

However, that should apply only to the actual decoding calls, not to the
failures elsewhere (e.g. configuring filters).

f6772e9bf8 avconv: make sure the filtergraph is freed on init failure 
The filtergraph's existence is used in several places to mean that the
filtergraph is fully configured. This causes problems if it's allocated,
but the initialization fails (e.g. if a non-existent filter is
specified).

b57e38f52c ac3dsp: x86: Replace inline asm for in-decoder downmixing with standalone asm 
Adds a wrapper function for downmixing which detects channel count changes
and updates the selected downmix function accordingly.

83548fe894 lavf: fix usage of AVIOContext.seekable 
It is supposed to be a flag. The only currently defined value is
AVIO_SEEKABLE_NORMAL, but other ones may be added in the future.
However all the current lavf code treats this field as a bool (mainly
for historical reasons).
Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.

086e4b58b5 vaapi_encode: Sync to input surface rather than output 
While outwardly bizarre, this change makes the behaviour consistent
with other VAAPI encoders which sync to the encode /input/ picture in
order to wait for /output/ from the encoder.  It is not harmful on
i965 (because synchronisation already happens in vaRenderPicture(),
so it has no effect there), and it allows the encoder to work on
mesa/gallium which assumes this behaviour.
