1632b40982 mpeg4: fix timestamp issues on too fast playback.
Improve generation of presentation timestamps to be less sensitive
to input stream errors. In practise, GOP is also a synchronization
point for PTS calculation.

60b5c2da97 mpeg4: fix handling of temporal reference distances.
TRD and TRB fields are not large enough to hold the difference of PTS
expressed with nanosecond resolution. So, compute them from the original
VOP info.

9c8b85b3c7 mpeg2: fix decoding of high profile streams.
Allow MPEG-2 High profile streams only if the HW supports that profile
or no High profile specific bits are used, and thus Main profile could
be used instead. i.e. chroma_format is 4:2:0, intra_dc_precision is not
set to 11 and no sequence_scalable_extension() was parsed.

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.

b33dd69300 mpeg4: improve error checking while decoding packets.
decode_picture() could return an error when an MPEG-4 profile is not
supported for example. In this case, the underlying VA context is not
allocated and no other proper action can be taken. Likewise on exit
from decode_slice().

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.

b56ac16224 decoder: add first-field flag to picture.
Add first-field (FF) flag to GstVaapiPicture, thus not requiring is_first_field
member in each decoder. Rather, when a GstVaapiPicture is created, it is considered
as the first field. Any subsequent allocated field will become the second field.

a7ec623279 decoder: fix semantics of SKIPPED pictures.
If GstVaapiPicture has flag SKIPPED set, this means gst_vaapi_picture_output()
will not push the underlying surface for rendering. Besides, VC-1 skipped P-frame
has nothing to do with rendering. This only means that the currently decoded
picture is just a copy of its reference picture.

not be alternating between top/bottom fields.

d43f3dc50a decode: delay NEWSEGMENT event if vaapidecode element was not linked.
Rationale: playbin2 links all elements at run-time. Once vaapidecode
is created and a NEWSEGMENT event arrives, downstream element may not
be ready yet. So, delay this event until next element is chained in,
otherwise basesink could output "Received buffer without a new-segment.
Assuming timestamps start from 0".
