Martin Storsjö	79d332ebbd	aarch64: vp9itxfm: Move the load_add_store macro out from the itxfm16 pass2 function This allows reusing the macro for a separate implementation of the pass2 function. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago

Martin Storsjö	115476018d	aarch64: vp9itxfm: Make the larger core transforms standalone functions This work is sponsored by, and copyright, Google. This reduces the code size of libavcodec/aarch64/vp9itxfm_neon.o from 19496 to 14740 bytes. This gives a small slowdown of a couple of tens of cycles, but makes it more feasible to add more optimized versions of these transforms.

Martin Storsjö	0331c3f5e8	arm: vp9itxfm: Make the larger core transforms standalone functions This work is sponsored by, and copyright, Google. This reduces the code size of libavcodec/arm/vp9itxfm_neon.o from 15324 to 12388 bytes. This gives a small slowdown of a couple tens of cycles, up to around 150 cycles for the full case of the largest transform, but makes it more feasible to add more optimized versions of these transforms.

Martin Storsjö	57ec83e424	omx: Use the EOS flag to handle flushing at the end This avoids having to count the number of frames sent to the codec and the number of output packets received; instead just wait until the encoder returns a buffer with the EOS flag set.

Martin Storsjö	58d87e0f49	aarch64: vp9itxfm: Restructure the idct32 store macros This avoids concatenation, which can't be used if the whole macro is wrapped within another macro. This is also arguably more readable. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago

wm4	577326d430	lavc: deprecate refcounted_frames field No deprecation guards, because the old decode API (for which this field is needed) doesn't have any either. This field should be removed together with the old decode calls. Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago

Mark Thompson	ca62236a89	vaapi_encode: Add VP8 support	8 years ago
Mark Thompson	ff35aa8ca4	vaapi_encode: Pass framerate parameters to driver Only do this when building for a recent VAAPI version - initial driver implementations were confused about the interpretation of the framerate field, but hopefully this will be consistent everywhere once 0.40.0 is released.	8 years ago
Mark Thompson	eddfb57210	vaapi_h264: Enable VBR mode Default to using VBR when a target bitrate is set, unless the max rate is also set and matches the target. Changes to the Intel driver mean that min_qp is also respected in this case, so set a codec default to unset the value rather than using the current default inherited from the MPEG-4 part 2 encoder.	8 years ago
Mark Thompson	f033ba470f	vaapi_encode: Support VBR mode This includes a backward-compatibility hack to choose CBR anyway on old drivers which have no CBR support, so that existing programs will continue to work their options now map to VBR.	8 years ago

Anton Khirnov	c3e84820d6	h264dec: export cropping information instead of handling it internally	8 years ago
Anton Khirnov	4fded0480f	h264dec: be more explicit in handling container cropping The current condition can trigger in cases where it shouldn't, with unexpected results. Make sure that: - container cropping is really based on the original dimensions from the caller - those dimenions are discarded on size change The code is still quite hacky and eventually should be deprecated and removed, with the decision about which cropping is used delegated to the caller.	8 years ago
Anton Khirnov	a02ae1c683	hevcdec: export cropping information instead of handling it internally	8 years ago
Anton Khirnov	019ab88a95	lavc: add an option for exporting cropping information to the caller Also, add generic code for handling cropping, so the decoders can export just the cropping size and not bother with the rest.	8 years ago
Anton Khirnov	b68e353136	qsvdec: do not sync PIX_FMT_QSV surfaces Introducing enforced sync points in arbitrary places is bad for performance. Since the vast majority of receiving code (QSV VPP or encoders, retrieving frames through hwcontext) will do the syncing, this change should not be visible to most callers. But bumping micro just in case. This is also consistent with what VAAPI hwaccel does.	8 years ago
