ec15caff93 codecs: mpeg2decoder: rename variables 
Since prev_picture and next_picture are plain pointers, not pointer to pointers,
it's misleading to name them with _ptr suffix.

41d2edc964 codecs: mpeg2decoder: Creating the field based on its arriving time. 
Spec says:
In a frame picture top_field_first being set to ‘1’ indicates that the
top field of the reconstructed frame is the first field output by the
decoding process. top_field_first being set to ‘0’ indicates that the
bottom field of the reconstructed frame is the first field output by
decoding process.

Here, the "output" should be interpreted just as the output order, not
including the decoding order. The field should be decoded as the order
they comes in the stream. Namely, no matter top_field_first is 0 or 1,
the first coming field is the first one to be decoded.

459abad096 codecs: Add buffer_flags for mpeg2 picture. 
We need to store the buffer flags such as GST_VIDEO_BUFFER_FLAG_INTERLACED
and GST_VIDEO_BUFFER_FLAG_TFF for interlaced video. Without these flags,
the VPP and display elements can not apply filter correctly.

c4aaeb0509 codecparsers: av1: Add an API to reset the annex_b state only. 
In practice, we encounter streams that have one or more temporal units
error. When that kind of error temporal units is in annex b format, the
whole temporal unit should be discarded.
But the temporal units before it are correct and can be used. More
important, because of the error temporal unit, the parser is in a wrong
state and all later temporal unit are also parsed uncorrectly.
We need to add this API to reset the annex_b state only when we meet
some temporal unit error.

113867766e codecs: vp9decoder: Add segmentation to picture. 
VA-API needs AC and DC quant scales for both luma and chroma, and the loop
filter level for current frame, but these values are not available outside
the private GstVp9Parser structure. And these values may change from frame
to frame, so they are picture specific.

This patch add GstVp9Segmentation structure array to GstVp9Picture to expose
it to derived classes. This approach is safer than passing the parser at
picture handling flow.

Also, this patch, in order to solve Documentation CI, mark as private the
GstVp9Picture structure.

5e3c7f2092 codecs: vp9decoder: Pass parser as new_sequence() parameter. 
In order to know the chroma format, besides profile, subsampling_x and
subsampling_y are needed (Spec 7.2.2 Color config semantics). These values are
in GstVp9Parser but not in  GstVp9Framehdr.

Also, bit_depth is available in parser but not frame header. Evenmore, those
values are copied to picture structure later.

In case of VA-API, to configure the pipeline, it is require to know the chroma
format and depth.

It is possible to know chroma and depth through caps coming from vp9parser, but
it requires string parsing. It would be less error prone to get these values
through the parser structure at new_sequence() virtual method.

Move the show_frame check from sub class to vp8 decoder's base class.
Calling the sub class' output_picture() function only when the frame
is displayed and marking the other automatically as decode only.
