| | | | | | | | | | | | | | | | Some clients incorrectly set 24 as bits_per_coded_sample, while the actual value is preserved in one of the codec headers. In order to work around this, delay the check until decode_frame(). Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* | libavcodec/x265: detect csps in libx265_encode_init_csp()Steve Borho2015-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this change, if you link with an 8bit libx265 and try to specify a 10bit input color space via: ffmpeg -i in.mov -c:v libx265 -pix_fmt yuv420p10le out.mp4 It will error with: Incompatible pixel format 'yuv420p10le' for codec 'libx265', auto-selecting format 'yuv420p' With this fix, it will learn if a 10bit libx265 is available at startup, and thus allow 10bit input color spaces.

| * | vp9: match another find_ref_mvs() bug in libvpx.Ronald S. Bultje2015-05-16
| | | | | | | | | | | | | | | | | | | | | If we find a second non-sub8x8 motion vector for a non-first sub8x8 block, and the clamped value is identical to the first non-sub8x8 motion vector, then the resulting nearmv motion vector is forced to zero.

| | | | | | | | | | | | To match the obscure clipping bug behaviour in libvpx.
| * | vp9: improve signbias check.Ronald S. Bultje2015-05-15
| | | | | | | | | | | | | | | Otherwise it will still scale motion vectors, which leads to corrupted prediction.
| * | vp9: don't allow compound references if error_resilience is enabled.Ronald S. Bultje2015-05-15
| | | | | | | | | | | | | | | | | | libvpx (probably accidentally) clears the bits if error_res is set, along with keyframe/intraonly. This probably wasn't the intention (since it's local data), but it's behaviour we have to copy...

| * | vp9: clip motion vectors in the same way as libvpx does.Ronald S. Bultje2015-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The practical effect of this is that the scaling will wrongly not be applied to the interpolation edge (the 3/4 constants in this patch). In other words, we clip to the pre-scaling interpolation, even though these should be clipped post-scaling. The resulting out-of-frame MVs are thus automatically clipped within the visible portion of the frame, which is probably not the intention, but is unfortunately what libvpx does, so we need to copy that behaviour.
| * | vp9: set skip flag if the block had no coded coefficients.Ronald S. Bultje2015-05-14
| | | | | | | | | | | | | | | | | | This reproduces libvpx behaviour. It seems like it originally only targeted loopfilter behaviour, but this unfortunately effects following block contexting and thus directs bitstream sync.

| | | | | | | | | | | | | | | For idct16, only when called from a adst16x16 variant, so impact is minor. For idct32, for all, so relatively major impact.
