vdpau: have av_vdpau_bind_context() fail on unsupported flag
Merged-by: Michael Niedermayer <michaelni@gmx.at>
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).

vdpau: common support for managing the VdpDecoder in avcodec
Conflicts:
libavcodec/vdpau.c
Merged-by: Michael Niedermayer <michaelni@gmx.at>
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).

This is necessary to recreate the decoder with the correct parameters,
as not all codecs invoke get_format() in this case.
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.
The application is still responsible for creating the VDPAU device
and allocating video surfaces - this is necessary to keep video
surfaces on the GPU all the way to the output. But the application
will no longer needs to care about any codec-specific aspects.

The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().
ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.
NULL pointer checks are added to ff_thread_release_buffer() stub function.

This gets rid of aliasing completely unrelated structs to Picture.
Fixes the remaining compilation warnings in the vdpau code.
Signed-off-by: Anton Khirnov <anton@khirnov.net>
The code passed H264Picture* and Picture*, and assumed the
hwaccel_picture_private field was in the same place in both
structs. Somehow this happened to work in Libav, but broke in
FFmpeg (and probably subtly breaks in Libav too).

Keeping support for the old VDPAU API has been requested by our VDPAU maintainer
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
Using VDPAU correctly means checking for preemption
and possibly regenerating the context all the time.
With the current API there is no context or other
user-defined pointer and thus this in not possible
during decoding unless using some hack like global
variables.
The need to reinitialize both surfaces and even function
pointers makes handling preemption even more difficult.
This patch introduces a new render2 function that gets
both the AVCodecContext and AVFrame in addition,
in both the user can store additional opaque data.
This allows even advanced approaches like keeping a
"generation counter" for the surfaces so they can be
regenerated on the fly and efficiently.
In addition, the function has a return value that will
be passed through all the way instead of being silently
ignored as for the current render function.
Unfortunately the HWAccel API has no way of providing
API/ABI compatibility, so a currently disallowed
state (render pointer being NULL) is used to extend it.
