7f47ac3bea Drop FFmpeg-based decoders. 
GStreamer codecparsers-based decoders are the only supported decoders now.
Though, FFmpeg decoders are still available in gstreamer-vaapi 0.3.x series.

5975def8ab mpeg2: allocate dummy picture for first field based I-frame. 
In P-pictures, prediction shall be made from the two most recently
decoded reference fields. However, when the first I-frame is a field,
the next field of the current picture could be a P-picture but only a
single field was decoded so far. In this case, create a dummy picture
with POC = -1 that will be used as reference.

Some VA drivers would error out if P-pictures don't have a forward
reference picture. This is true in general but not in this very specific
initial case.

75538bbc9b decoder: use POC to maintain the DPB. 
Introduce a POC field in GstVaapiPicture so that to store simpler sequential
numbers. A signed 32-bit integer should be enough for 1 year of continuous
video streaming at 60 Hz.

Use this new POC value to maintain the DPB, instead of 64-bit timestamps.
This also aligns with H.264 that will be migrated to GstVaapiDpb infrastructure.

d51bb87482 mpeg2: rework generation of presentation timestamps. 
Always prefer PTS from the demuxer layer for GOP times. If this is invalid,
i.e. demuxer could not determine the PTS or the generated PTS is lower than
max PTS from past pictures, then try to fix it up based on the duration of
a frame.

For picture PTS, simply use the GOP PTS formerly computed then use TSN to
reconstruct a current time. Also now handle wrapped TSN correctly.

ab94048ea0 decoder: fix double buffer free with some VA drivers. 
vaRenderPicture() implicitly disposes VA buffers. Some VA drivers would
push the VA buffer object into a list of free buffers to be re-used. However,
reference pictures (and data) that was kept would explicitly release the VA
buffer object later on, thus possibly destroying a valid (re-used) object.

Besides, some other VA drivers don't support correctly the vaRenderPicture()
semantics for VA buffers disposal and would leak memory if there is no explicit
vaDestroyBuffer(). The temporary workaround is to explcitily destroy VA buffers
right after vaRenderPicture(). All VA drivers need to be aligned.

4a46b5d6c4 decoder: retain proxy surface until the GstVaapiPicture is destroyed. 
Keep a valid reference to the proxy in GstVaapiPicture so that frames
marked as "used for reference" could be kept during the lifetime of the
picture. i.e. don't release them too soon as they could be re-used right
away.

da3948bdeb Use a recursive mutex so that a single thread can lock 
several times. This fixes decoding of MPEG-2 and H.264
because those created a GstVaapiContext later through
avcodec_decode_video() that was a protected call.
