Denis Charmet	38f99017e6	vp9: Return the correct size when decoding a superframe According to avcodec.h, avcodec_decode_video2 should return the number of bytes used if a frame was decoded. The current implementation returns size - used size of all the subframes. This fixes the VLC's bug https://trac.videolan.org/vlc/ticket/16836. The superframe is always fully consumed.

Ronald S. Bultje	5307adadeb	vp9: only call ff_get_format on stream format changes. In practice, this means we don't call it N times for N-threaded decoding. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Ganesh Ajjanagadde	2cbaa078d1	avcodec: use HAVE_THREADS header guards to silence -Wunused-function When compiled with --disable-pthreads, e.g http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7, a bunch of -Wunused-functions are reported due to missing header guards around threading related functions. This patch should silence such warnings. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Ronald S. Bultje	a0d8a81075	vp9: switch min_tile_cols location so it shifts up instead of down. This fixes cases where the shifted number is 64, but we shifted non- zero numbers away in the shift. The change makes behaviour consistent with libvpx.	9 years ago

Ronald S. Bultje	fd8b90f5f6	vp9: fix overflow in 8x8 topleft 32x32 idct ssse3 version. Also disable the mmx/iwht optimization when the bitexact flag is set. With synthetically coded coefficients (i.e. these that lead to a residual well outside the [-255,255] range), our optimizations will overflow. It doesn't make sense to fix the overflows, since they can only occur on synthetic input, not on real fwht-generated input. Thus, add a bitexact flag that disables this optimization.	9 years ago

Ronald S. Bultje	9cdeb105a6	vp9: do unscaled MC in scaled path if size of this reference matches. This can happen if we do bidirectional MC, where one reference has the same size as the current frame, but the other one doesn't.	9 years ago

Andreas Cadhalpun	b18eac7ff2	vp9: change type of tile_size from unsigned to int64_t Otherwise the check 'tile_size < size' treats a negative size as unsigned, causing the check to pass.

Ronald S. Bultje	32b6d31ef3	vp9: don't allow compound references if error_resilience is enabled. libvpx (probably accidentally) clears the bits if error_res is set, along with keyframe/intraonly.
