Mark Thompson	5a5df90d9c	vaapi_h265: Add main 10 encode support	8 years ago
Mark Thompson	b8cac1e830	vaapi_h265: Fix buffering parameters A decoder may need this to be set correctly to output frames in the right order.	8 years ago
Mark Thompson	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.	8 years ago

Mark Thompson	17a0f9481c	vaapi_h264: Fix CFR mode with frame_rate set in AVCodecContext	8 years ago
Mark Thompson	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.	8 years ago

Justin Ruggles	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. Simplification and porting to current x86inc infrastructure by Diego Biurrun. Signed-off-by: Diego Biurrun <diego@biurrun.de>	8 years ago
Justin Ruggles	a9ba59591e	ac3dsp: Add some special-case handling for the C downmix function This is about 200% faster for in-decoder downmixing of 5.0 and 5.1 content. Signed-off-by: Diego Biurrun <diego@biurrun.de>	8 years ago
Justin Ruggles	43717469f9	ac3dsp: Reverse matrix in/out order in downmix() Also use (float *) instead of (float ()[2]). This matches the matrix layout in libavresample so we can reuse assembly code between the two. Signed-off-by: Diego Biurrun <diego@biurrun.de>	8 years ago

Diego Biurrun	3281d823cd	intrax8: Change type of array stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar. Also rename all such parameters to "stride" for consistency.	8 years ago

Mark Thompson	956a54129d	vaapi_h264: Set max_num_ref_frames to 1 when not using B frames	8 years ago
Mark Thompson	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.	8 years ago
Mark Thompson	892bbbcdc1	vaapi_encode: Check packed header capabilities This improves behaviour with drivers which do not support packed headers, such as AMD VCE on mesa/gallium.	8 years ago
Mark Thompson	80a5d05108	vaapi_encode: Refactor initialisation This allows better checking of capabilities and will make it easier to add more functionality later. It also commonises some duplicated code around rate control setup and adds more comments explaining the internals.	8 years ago
