Anton Khirnov 15ee419b7a pcx: properly pad the scanline 
It is passed to the get_bits API, which requires buffers to be padded.

Anton Khirnov bba9d8bdfb qpeg: fix an off by 1 error in the MV check 
height - me_y is the line from which we read, so it must be strictly
smaller than the frame height. Fixes possible invalid reads in corrupted
files.

Also, use a proper context for logging the error.

Anton Khirnov 796dca027b alac: do not return success if nothing was decoded 
If we encounter an END element before anything is decoded, we would
return success even though the output frame has not been allocated,
which is invalid.

Mark Thompson 5a667322f5 vaapi_vc1: Remove redundant version check

Mark Thompson 121f34d5f0 hwcontext_vaapi: Try the first render node as the default DRM device 
If no string argument is supplied when av_hwdevice_ctx_create() is
called to create a VAAPI device, we currently only try the default
X11 display (that is, $DISPLAY) to find a device, and will therefore
fail in the absence of an X server to connect to.  Change the logic
to also look for a device via the first DRM render node (that is,
"/dev/dri/renderD128"), which is probably the right thing to use in
most simple configurations which only have one DRM device.

Ronald S. Bultje bc6e0b64a9 vp9: split last/cur_frame from the reference buffers. 
We need more information from last/cur_frame than from reference
buffers, so we can use a simplified structure for reference buffers,
and then store mvs and segmentation map information in last/cur.

This prepares the decoder for frame threading support.

Anton Khirnov 04763c6f87 h264_direct: use the reference mask from the actual reference 
Not from the underlying frame. Fixes races with frame threading in
field-coded files, where decoding would wait for the wrong field (e.g.
random failures in mixed-nal-coding).

of av_buffer_pool_uninit(). Also, this function is to be called by the
caller, not the pool itself.

Anton Khirnov 24a362569b buffer: fix av_buffer_realloc() when the data is offset wrt buffer start 
In such a case behave as if the buffer was not reallocatable -- allocate a
new one and copy the data (preserving just the part described by the
reference passed to av_buffer_realloc).
