He Junyan 7e33863b10 codecparsers: av1: all ref idx should be gint8. 
All the ref index need to compare with 0 in reference index decision
algorithm. We also need to init them to -1.

Seungha Yang 88ebe8031a codecs: h264decoder: Add more option arguments for reference picture getter 
In case that "pic_order_cnt_type" is equal to zero, ref picture
list for B slice should not include non-existing picture
as per spec 8.2.4.2.3. And, the second field is not needed
for the process of frame picture reference list construction
since it needs to be frame unit, not field picture in that case.

Seungha Yang 11509fded1 codecs: h264decoder: Don't try to construct RefPicList0 and RefPicList1 if not required 
We were trying to construct reference picture list even for
I slice before this commit. Reference list is required only for
P, SP and B slices. Also, if all existing reference pictures
are gap pictures, we don't need to construct lists.

Seungha Yang f9af93d841 codecs: h264decoder: Don't give up to decode due to missing reference picture 
Missing reference picture is very common thing for broken/malformed stream.

Seungha Yang 0b9f975b36 codecs: h264decoder: Add support for interlaced stream 
Initial support for interlaced stream. Subclass should implement
new_field_picture() vfunc. Otherwise, baseclass will assume that
subclass doesn't support interlaced stream.

Restrictions:
* Reference picture modification process for interlaced stream
  is not implemented yet
* PAFF (Picture Adaptive Frame Field) is not properly implemented.
* Field display ordering (e.g., top-field-first) decision should
  be enhanced via picture timing SEI parsing
* Gap in field picture should be handled

Seungha Yang 7a53d7a4aa codecs: h264decoder: Store reference picture type using enum value 
Managing reference picture type by using two variables
(ref and long_term) seems to be redundant and that can be
represented by using a single enum value.

This is to sync this implementation with gstreamer-vaapi so that
make comparison between this and gstreamer-vaapi easier and also
in order to minimize the change required for subclass to be able
to support interlaced.

Edward Hervey dd425fe0fd adaptivedemux: Store QoS values on the element 
Storing it per-stream requires taking the manifest lock which can apparenly be
hold for aeons. And since the QoS event comes from the video rendering thread
we *really* do not want to do that.

Storing it as-is in the element is fine, the important part is knowing the
earliest time downstream.
