Hendrik Leppkes	42ff56e362	lavc: fix profile declarations for vdpau decoders	9 years ago
Anton Khirnov	2c6811397b	lavc: add profiles to AVCodecDescriptor The profiles are a property of the codec, so it makes sense to export them through AVCodecDescriptors, not just the codec implementations.	9 years ago
Philip Langdale	91f1115a0e	avcodec/vc1dec: Re-order init to avoid initting hwaccel too early 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.

Gwenole Beauchesne	9f8e57efe4	vaapi: define a unique pixel format for VA-API (AV_PIX_FMT_VAAPI). Deprecate older VA pixel formats (MOCO, IDCT) as it is now very unlikely to ever be useful in the future. Only keep plain AV_PIX_FMT_VAAPI format that is aliased to the older VLD variant. This is an API change. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>	9 years ago

Vittorio Giovara	31a117a0e6	mpegvideo: msmpeg4: Move function declarations	10 years ago
Philip Langdale	9ae766d1c6	avcodec/vdpau: Re-factor pre-hwaccel helper functions into separate header 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).
