BGRx format can be supported with Msdk's RGB4

prpose_allocation:
-- always instantiate a pool for for upstream
-- use async_depth + 1 as min buffer count

decide_allocation:
-- always create a new bufferpool for source pad.
Each of the msdk element has to create it's own mfxsurfacepool
which is an msdk contraint. For eg: Each Msdk component (vpp, dec and
enc)
will invoke the external Frame allocator for video-memory usage
So sharing the pool between gst-msdk elements might not be a good idea.

We were assuming that NULL pool meant that downstream didn't reply.
Update the pool index 0 instead of adding at the end. Otherwise we ended
up letting basesrc decide, which would pick the blocksize as a size
(4096) instead of the image size.

This server uses an unknown 003.889 protocol version. This patch fixes
the version validation in order to simply fallback to 3.3 as suggested
by the spec.

Just like the autotools build.

Those profiles have been added in the version 2012-01
and 2011-06 of the AVC spec.

If the "output-cc" property is set to TRUE and there is CC present
in the VBI Ancillary Data, they will be extracted and set on the
outgoing buffer as GstVideoCaptionMeta.

Only CDP packets are supported.

Well, just look for same version as we require for -base
which should be good enough. Also use plugins base req
for -base libs.

We would mark all streams with FLAG_UNSELECT as we would check
the pointer for non-NULLness not the dereferenced stream number
(and the pointer is always non-NULL). The intention here was
presumably to mark the first stream of each type as SELECT and
the others as UNSELECT by default.

CID 1434970.

CID 1434971

If that threshold is reached, `iqa` will emit an ERROR message on the
bus, stopping any processing.

This way we can do a simpler comparison with gst-validate and the
process will error out if the specified threshold is reached.

This is a simple Bin that will expose audiotestsrc or videotestsrc
based on what is asked by the user either through the GstURIHandler
API or through the "stream-types" property.

This element also provides GstStream and GstStreamCollection
so it is nicely usable from playbin3.

The clock seems to have a lot of drift (or we're using it incorrectly)
which causes buffers to be late on the sink and get dropped.

Disable till someone can investigate whether our usage of the API is
incorrect (it looked correct to me) or if something is wrong.

Since cuda-tools 9.0, nvcuvid.h is replaced by dynlink_nvcuvid.h.
This patch changes nvdec to use run-time dynamic linking if
cuda-tools version >= 9.
nvenc does not require any change since its necessary headers are
still available.

Using the default value (InterleavedDec == MFX_SCANTYPE_UNKNOWN)
causing issues with non-interleaved sample decode. Ideally the usage
of MFXVideoDECODE_DecodeHeader should fix these type of issue, but
it seems to be not. But hardcoding the InterleaveDec to
MFX_SCANTYPE_NONINTERLEAVED
is fixing the problem and fortunately msdk seems to be taking care of
Interleaved samples
too .So let's hardcode it for now.

pcapparse cannot parse fragmented IP packets correctly, in particular it
will get confused when trying to parsing fragments as standalone frames
in two ways:

  1. the first fragment will have the packet length greater than the
     frame size and will always be discarded;

  2. fragments with non-zero offsets will be interpreted as full packets
     and the first part of their raw payload data will be parsed as the
     transport protocol header, resulting in bogus values for addresses
     and ports, thus evading the properties filtering on those values.

This can make it difficult for users to see why the data does not get
downstream.

So be more explicit and just bail out when fragmented packets are
encountered.
