face578d56 Rewrite emu_edge functions to have separate src/dst_stride arguments.
This allows supporting files for which the image stride is smaller than
the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file
or a 16x16 VP8 file with -fflags +emu_edge.

c341f734e5 Convert multiplier for MV from int to ptrdiff_t.
This prevents emulated_edge_mc from not undoing mvy*stride-related
integer overflows.

5f24fe82e5 mpegvideo: Initialize chroma_*_shift and codec_tag even if the size is 0
This fixes breakage in a few fate tests on certain setups
(that for some reason didn't break on OS X) after the previous
commit (8812a8057). Currently, some video streams are initialized
in ff_MPV_common_init with width/height set at 0 and only changed
to a proper video size with ff_MPV_common_frame_size_change later.

The breakage was diagnosed by Anton Khirnov.

be reallocated after a frame size change. Since we have now reference
counted buffers we can unref the buffers immediately.

259af1b923 mpegvideo: allocate sufficiently large scratch buffer for interlaced vid
MPV_decode_mb_internal needs 3 * 16 * linesize bytes of scratch buffer

For interlaced content, linesize is multiplied by two after the allocation
of the scratch buffer, and the dest_cr pointer ends past the buffer.

This patch makes ff_mpv_frame_size_alloc allocate a total of
(aligned line_size) * 2 * 16 * 3 bytes, which suffices even for the
interlaced case.

c3ebfcd6e1 mpegvideo: allocate hwaccel privdata after the frame buffer
This ensures the hwaccel privdata does not leak when a frame buffer could
not be allocated (and toggle the assert when the frame is re-used).
Having no frame buffer available is quite common when using the DXVA2
hwaccel in situations where the DXVA2 renderer is being re-allocated, for
example when moving between displays.
