This is not merged as it breaks a good part of the error concealment/resilience for H.263 Also, messenger.h263 plays fine in ffmpeg. If anyone has any other h263 files that do not work, please open an issue on trak or mail me! See: d225b0f7aaa65eafccc87165130e1c4bab71708b Merged-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | | | | | | | | | | | | | The register function now specifies that the user callback should leave things in the same state that it found them on failure but that failure to destroy is ignored by the library. The register function is now explicit about its behavior on failure (it unregisters the previous callback and destroys all mutex).

| | | | | | | | | | | | | | | | | | | | | | | | 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>

| * vdpau: common support for managing the VdpDecoder in avcodecRémi Denis-Courmont2014-10-05
| | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Anton Khirnov <anton@khirnov.net>
