a926511df4 codecs: mpeg2decoder: decode only if B and not closed gop 
Mark as decode only if picture type is B, without previous picture in DBP and
closed_gop is 0 as might be understood in "6.3.8 Group of pictures header".

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.

Instead of implementing exactly the same thing ourself but making

Since we are *sure* that the bus can't have been access at the point
where we add the watch we are guaranteed that the current thread
maincontext is going to be used.

Context creation and retrieval is required, the symbols are exported
with the header missing. Users most likely define GST_USE_UNSTABLE_API
so they're aware of the implications of using a header that might change

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.
