cd3a3534c4 msdk: use a new method to create mfx session when using oneVPL dispatcher
In oneVPL, MFXLoad() and MFXCreateSession() are required to create a
workable mfx session[1]

fbd1d0cecb msdk: add a helper function to get codename of the platform
The features supported in MSDK vary from platform to platform. We may
support some features based on the codename of the platform in future.

b18be3562c msdk: ignore MFX_ERR_UNDEFINED_BEHAVIOR when loading a plugin
An issue can be seen when using msdkh265enc with bitrate change in
playing state. The root cause is the corresponding plugin is loaded
again.

Returning MFX_ERR_UNDEFINED_BEHAVIOR from MSDK just means the plugin has
been loaded, so we may ignore this error when doing configuation again
in the sub class, otherwise the pipeline will be interrupted

54c5ebbd53 msdk: Remove all DMABuf caps features on Windows
Add new macro for sink/src pad template to ensure no DMABuf caps
features are exposed on Windows. Some DMABuf caps features
were not handled by the commit 9ec62418c3

d5fd9bc22b msdkvpp: support video-direction property
video-direction property is common property in gstreamer. In addition,
both mirroring & rotation properties are marked as deprecated,
video-direction will override mirroring & rotation properties when they
are set explicitly

ef81c9d6c4 msdkdec: Update frame info from video parameters
A 10bit stream may have different depth values for Luma and Chroma, and
MSDK requires the frame info must match the corresponding video
parameters

20f61db2e5 msdkdec: make sure mfx frame width/height meets MSDK's requirement
It is possible that the output region size (e.g. 192x144) is different
from the coded picture size (e.g. 192x256). We may adjust the alignment
parameters so that the padding is respected in GstVideoInfo and use
GstVideoInfo to calculate mfx frame width and height

This fixes the error below when decoding a stream which has different
output region size and coded picture size

fda4918cc8 msdk: don't use hard-coded video format
Some codecs may support varied formats, e.g. HEVC may support NV12
and P010_10LE etc

dec0953517 msdk: allow building against open sourced msdk
Building against mfx_dispatcher is used to search for
headers in PREFIX/include/mfx/ only (commit: 62f04e801b),
but it is just PREFIX/include with open source msdk version.

275d754156 msdk: fix plugin load on implementations with only HW support
We can't assume that MSDK always supports SW implementation
on all platforms.  Thus, msdk_is_available should check for
ANY implementation.

580a52ec49 msdkenc: use bufferpool
1\ Proposes msdk bufferpool to upstream.
  - If upstream has accepted the proposed msdk bufferpool,
    encoder can get msdk surface from the buffer directly.
  - If not, encoder get msdk surface its own msdk bufferpool
    and copy from upstream's frame to the surface.

2\ Replace arrays of surfaces with msdk bufferpool.

3\ In case of using VPP, there should be another msdk bufferpool
   with NV12 info so that it could convert first and encode.

Calls gst_msdk_set_frame_allocator and uses video memory only on linux.
and uses system memory on Windows until d3d allocator is implemented.

6ce9a66b80 msdk: implements GstMsdkContext.
Makes GstMsdkContext to be a descendant of GstObject so that
we could track the life-cycle of the session of the driver.

Also replaces MsdkContext with this one.
Keeps msdk_d3d.c alive for the future.
