* mpegvideo: Fix undefined negative shifts in ff_init_block_indexLuca Barbato2016-03-05

* idct8x8: Fix undefined negative shiftsKaterina Barone-Adesi2016-03-05
| | | | | | | | | | | The original code left-shifts negative values, which is undefined in the C99 specification (the one used during normal Libav compilation). This change multiplies by (1 << shift), which is functionally equivalent, but has defined behavior. With this change, fate-idct8x8 compiled with --fsanitize=undefined works. Bug-Id: 686

* qsv: Move down the implementation queryLuca Barbato2016-02-26
| | | | | The plugin loaded may not match the general implementation capability wise.
* avpacket: properly reset data/size in av_packet_move_ref()Anton Khirnov2016-02-26
| | | | | It currently just calls av_init_packet(), which does not touch those fields.

* vc1dec: Check group allocations separatedlyVittorio Giovara2016-02-25
| | | | This avoids accessing NULL pointers in case of error.

| | | | | The deinit function in the 'error' section will correctly free everything.

| | | | The reasoning is the same as for the corresponding qsvenc patch.
* qsvenc: store the sync point in heap memoryMaxym Dmytrychenko2016-02-24
| | | | | | | | The QSV runtime expects the sync point address passed to MFXVideoENCODE_EncodeFrameAsync() to be valid until MFXVideoCORE_SyncOperation(). Signed-off-by: Anton Khirnov <anton@khirnov.net>

* lavc: add codec parameters APIAnton Khirnov2016-02-23
| | | | | | This API is intended to allow passing around codec parameters without using full AVCodecContext (which also contains codec options and encoder/decoder state).
* x86: hevc: Fix linking with both yasm and optimizations disabledDiego Biurrun2016-02-23
| | | | | Some optimized functions reference optimized symbols, so the functions must be explicitly disabled when those symbols are unavailable.

| | | | | The WTV demuxer depends on large parts of the MPEG-TS demuxer internals anyway and fails to build without it.

* hevc: Track long and short term RPS size for VDPAUPhilip Langdale2016-02-13
| | | | | | | | | | | | | | | | Today, we track the short term RPS size for DXVA, but only if the SliceHeader RPS is being used. Otherwise it's left uninitialized. NVIDIA's VDPAU implementation requires that the size be accurately tracked even if an SPS RPS is being used. In this case, it's really counting the size of the RPS idx information, but you end up with mangled output if the value is not accurate. VDPAU also needs the size of the long term RPS.

* dxva2_hevc: properly signal the num_delta_pocs from the SPS RPSHendrik Leppkes2016-02-13
| | | | | | | | | ucNumDeltaPocsOfRefRpsIdx needs to contain the flat value from the SPS RPS, and not the final computed value from the slice header RPS, as this calculation is done internally by the driver again.

* nvenc: rename a misnamed functionAnton Khirnov2016-02-12
| | | | | This function copies the encoded bistream into the caller's packet, calling it 'get_frame' is misleading.
* nvenc: merge input and output surface structsAnton Khirnov2016-02-12
| | | | | An input frame always corresponds to exactly one output packet, so there is no point in complicating the situation by managing them separately.
