* lavc/qsvdec: Add GPU-accelerated memory copy supportLinjie Fu2019-10-09
| | | | | | | | | | | | | | | | GPU copy enables or disables GPU accelerated copying between video and system memory. This may lead to a notable performance improvement. Memory must be sequent and aligned with 128x64.

* lavc/qsvdec: Replace current parser with MFXVideoDECODE_DecodeHeader()Zhong Li2019-08-20
| | | | | | | | | | | | | | | | | Using MSDK parser can improve qsv decoder pass rate in some cases (E.g: sps declares a wrong level_idc, smaller than it should be). And it is necessary for adding new qsv decoders such as MJPEG and VP9 since current parser can't provide enough information. Actually using MFXVideoDECODE_DecodeHeader() was disscussed at https://ffmpeg.org/pipermail/ffmpeg-devel/2015-July/175734.html and merged as commit 1acb19d, but was overwritten when merged libav patches (commit: 1f26a23) without any explain. Split decode header from decode_init, and call it for everyframe to detect format/resoultion change. It can fix some regression issues such as hevc 10bits decoding.

* lavc/qsv_hevc: correct QSV HEVC default plugin on WindowsZhong Li2018-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | 1. Old logic meaned: everywhere, except Windows, ffmpeg has to use HW acceleration, but on Windows ffmpeg has to use (unavailable) software HEVC by default 2. Software HEVC is available only if you provide corresponding software MediaSDK library, which isn't provided with ffmpeg. More information could be found in https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/samples/readme-encode_linux.pdf 3. HW HEVC decoding/encoding are available on Windows in the driver by default Note: Default case should be the most common case but this change still has potential risk on windows if HW path is not supported(or doesn't work as expection). (See the historical disscution: https://lists.libav.org/pipermail/libav-devel/2016-November/080419.html). In such case, two options suggested: 1. Use the option "-load_plugin hevc_sw" to switch SW path manually. 2. Or report bug to Intel windows driver if your GPU can support HEVC HW codec. (HEVC decoding is supported since Braswell, and encoding supported since Skylake) Patch started by Landgraph. Add similar change for hevc decoder and bump a new version.

* lavc/qsvdec: flush buffered data before reinitLinjie Fu2018-11-06
| | | | | | | | | | | | | | | | | Flush the buffered data in libmfx before video param reinit in case the frames drop. Cache the first frame causing the reinit and decode zero-size pkt to flush the buffered pkt before reinit. After all the buffered pkts being flushed, resume to reinit and decode. Fix the issue in ticket #7399. [V2]: Move the definition of zero_pkt to where it is exactly used. Signed-off-by: Linjie Fu <linjie.fu@intel.com> Signed-off-by: Zhong Li <zhong.li@intel.com>

| * lavc: Add hardware config metadata for decoders supporting hardware outputMark Thompson2017-12-19
| | | | | | | | | | | | | | | | | | This includes a pointer to the associated hwaccel for decoders using hwaccels - these will be used later to implement the hwaccel setup without needing a global list. Also added is a new file listing all hwaccels as external declarations - this will be used later to generate the hwaccel list at configure time.
| * avcodec: add metadata to identify wrappers and hardware decoderswm42017-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>.
