b93315fa6c codecparsers: Exclude the size of obu_size when identify OBU. 
obu->obu_size does not contain the bytes of obu_size itself, we need
to exclude it when doing the saint check.

d16b5b7f7f d3d11: Allow building UWP features with Desktop features if possible 
WINAPI_PARTITION_DESKTOP and WINAPI_PARTITION_APP can coexist.
Although UWP only binaries should be used for production stage,
this change will be useful for development stage

86c009e7aa webrtc: expose transport property on sender and receiver 
As advised by !1366#note_629558 , the nice transport should be
accessed through:

> transceiver->sender/receiver->transport/rtcp_transport->icetransport

All the objects on the path can be accessed through properties
except sender/receiver->transport. This patch addresses that.

0f7af4b143 d3d11: Move core methods to gst-libs 
Move d3d11 device, memory, buffer pool and minimal method
to gst-libs so that other plugins can access d3d11 resource.
Since Direct3D is primary graphics API on Windows, we need
this infrastructure for various plugins can share GPU resource
without downloading GPU memory.
Note that this implementation is public only for -bad scope
for now.

ec15caff93 codecs: mpeg2decoder: rename variables 
Since prev_picture and next_picture are plain pointers, not pointer to pointers,

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.

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

with the header missing. Users most likely define GST_USE_UNSTABLE_API

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.
