* dxva2_hevc: re-write reference frame handlingHendrik Leppkes2015-05-29
| | | | | | | The old logic required and explicit clearing of the lists first and was prone to overflow the DXVA2 struct in some circumstances. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* | avcodec/mips: Split uni mc optimizations to new fileShivraj Patil2015-05-28
| | | | | | | | | | | | | | | | | | This patch moves HEVC code of uni mc cases to new file hevc_mc_uni_msa.c. (There are total 5 sub-modules of HEVC mc functions, if we add all these modules in one single file, its size would be huge (~750k) & difficult to maintain, so splitting it in multiple files) This patch also adds new HEVC header file libavcodec/mips/hevc_macros_msa.h Signed-off-by: Shivraj Patil <shivraj.patil@imgtec.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | | | | | | | Otherwise it will never be reset, and remain "stuck" in this state forever. Can happen when seeking: the decoder will receive fragments from different file positions, which triggers the condition easily. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* | avcodec/vdpau: Re-factor pre-hwaccel helper functions into separate headerPhilip Langdale2015-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | h264.h and hevc.h are mutually exclusive due to defining some of the same names. As such, we need to avoid forcing h264.h to be included if we want hevc decode acceleration to be possible. However, some of the pre-hwaccel helper functions need h264.h. To avoid messy collisions, let's move the declaration of all those helpers to a separate header which we will exclude for the hevc support (which will be hwaccel-only).

* | libshine: fix support for shine 3.0Andreas Cadhalpun2015-05-25
| | | | | | | | | | | | | | | | | | | | | | | | shine_encode_buffer expects written to be an int pointer, while the previous shine_encode_frame expected it to be a long pointer. Thus encoding with libshine currently always fails with "internal buffer too small", because a negative return value of shine_encode_buffer is interpreted as a very large long value.
