* lavc: Rename hwaccel.h to hwconfig.hMark Thompson2020-04-26
| | | | | This already applied to decoders as well as hwaccels, and adding encoder support was going to make the name even more inaccurate.

* avcodec/vc1: support multi-slice field interlaced pictures with hwaccelJerome Borsboom2018-06-17
| | | | | | | | | When using hardware accelerated decoding for multi-slice field interlaced pictures, only the first slice was decoded. This patch adds the neccesary looping over the remaining slices that may exist in field interlaced pictures. Additionally, we align the calculation of mby_start for the second field with the method given in VC-1 spec. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>

* lavc: Add hardware config metadata for decoders supporting hardware outputMark Thompson2017-11-26
| | | | | | | | | 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: Implement vc1 nvdec hwaccelPhilip Langdale2017-11-14
| | | | | This hwaccel is interesting because it also works for wmv3/9 content, which is not supported by the nvidia parser used by cuviddec.

* | dxva: add support for new dxva2 and d3d11 hwaccel APIswm42017-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This also adds support to avconv (which is trivial due to the new hwaccel API being generic enough). The new decoder setup code in dxva2.c is significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Merges Libav commit f9e7a2f95a7194a8736cc1416a03a1a0155a3e9f. Also adds untested VP9 support. The check for DXVA2 COBJs is removed. Just update your MinGW to something newer than a 5 year old release. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* | avcodec/vc1dec: Re-order init to avoid initting hwaccel too earlyPhilip Langdale2015-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least for vdpau, the hwaccel init code tries to check the video profile and ensure that there is a matching vdpau profile available. If it can't find a match, it will fail to initialise. In the case of wmv3/vc1, I observed initialisation to fail all the time. It turns out that this is due to the hwaccel being initialised very early in the codec init, before the profile has been extracted and set. Conceptually, it's a simple fix to reorder the init code, but it gets messy really fast because ff_get_format(), which is what implicitly trigger hwaccel init, is called multiple times through various shared init calls from h263, etc. It's incredibly hard to prove to my own satisfaction that it's safe to move the vc1 specific init code ahead of this generic code, but all the vc1 fate tests pass, and I've visually inspected a couple of samples and things seem correct.
