* avcodec/vdpau: Support for VDPAU accelerated HEVC decodingPhilip Langdale2015-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces basic support for HEVC decoding through vdpau. Right now, there are problems with the nvidia driver/library implementation that mean that frames are incorrectly laid out in memory when they are returned from the decoder, and it is normally impossible to recover the complete decoded frame due to loss of data from alignment inconsistencies. I obviously hope that nvidia will be fixing it in due course - I've verified the problems exist with their example application. As such, this support is not useful for any real world application, but I believe that it is correct (with the caveat that the mangled frames may hide problems) and will work properly once the nvidia problem is fixed. Right now it appears that any file encoded by x265 or nvenc is decoded correctly, but that's because these files don't use a bunch of HEVC features. Quick summary: Features that seem to work: 1) Short Term References 2) Scaling Lists 3) Tiling Features with known problems: 1) Long Term References It's hard to tell what's going on here. After I read the nvidia example app that does not set the IsLongTerm flag on LTRs, and changed my code, a bunch of frames using LTR started to display correctly, but there are still samples with glitches that are related to LTRs. In terms of real world files, both x265 and nvenc only use short term refs from this list. The divx encoder seems similar. Signed-off-by: Philip Langdale <philipl@overt.org>
* 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).

| * vdpau: add AV_HWACCEL_FLAG_IGNORE_LEVEL to skip the codec level checkRémi Denis-Courmont2014-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | Decoding acceleration may work even if the codec level is higher than the stated limit of the VDPAU driver. Or the problem may be considered acceptable by the user. This flag allows skipping the codec level capability checks and proceed with decoding. Applications should obviously not set this flag by default, but only if the user explicitly requested this behavior (and presumably knows how to turn it back off if it fails).

| | | | | | | | | | | | | | | | | | | | | | | | This function provides an explicit VDPAU device and VDPAU driver to libavcodec, so that the application is relieved from codec specifics and VdpDevice life cycle management. A stub flags parameter is added for future extension. For instance, it could be used to ignore codec level capabilities (if someone feels dangerous). Signed-off-by: Anton Khirnov <anton@khirnov.net>

| | | | | | | | | | | | | | | | | | | | | | | | Using the not so new init and uninit callbacks, avcodec can now take care of creating and destroying the VDPAU decoder instance.

But the application will no longer needs to care about any codec-specific aspects. Signed-off-by: Anton Khirnov <anton@khirnov.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the changes are just trivial are just trivial replacements of fields from MpegEncContext with equivalent fields in H264Context. Everything in h264* other than h264.c are those trivial changes. The nontrivial parts are: 1) extracting a simplified version of the frame management code from mpegvideo.c. We don't need last/next_picture anymore, since h264 uses its own more complex system already and those were set only to appease the mpegvideo parts. 2) some tables that need to be allocated/freed in appropriate places. 3) hwaccels -- mostly trivial replacements. for dxva, the draw_horiz_band() call is moved from ff_dxva2_common_end_frame() to per-codec end_frame() callbacks, because it's now different for h264 and MpegEncContext-based decoders. 4) svq3 -- it does not use h264 complex reference system, so I just added some very simplistic frame management instead and dropped the use of ff_h264_frame_start(). Because of this I also had to move some initialization code to svq3.
