Some streams have error data introducing unknown NAL type. There are
also kinds of NAL types we do not want to handle. The old manner will
set a decoder error when encounter this, which cause a latent crash bug.
The decoder may successfully decode the picture and insert it into DPB.
But there are error NAL units after the AU which cause the post unit error
and make that frame dropped. The later output of the picture still want
to ref that frame and crash.
No need to set decoder error when can not recognize or handle the NAL
unit, just skip it and continue.
Fix: #191
This patch makes use of GST_PARAM_USER_SHIFT to define the internal
param in encoders to decide which parameters to expose. Thus
gstreamer-vaapi will not interfere with any change in GStreamer in the
future.
Also, the internal symbol was change to
GST_VAAPI_PARAM_ENCODER_EXPOSURE to keep the namespacing.
The command line:
gst-launch-1.0 filesrc location=some_name.mjpeg ! jpegparse !
vaapijpegdec ! videoconvert ! video/x-raw,format=I420 ! vaapisink
will crash on i965 driver because of no pointer check.
We now generate the video format map between GST format and VA format
dynamically based on the image format returned by vaQueryImageFormats.
i965 driver does to report image format of 444P and Y800 forcc, while
the jpeg decoder context VASurfaceAttribPixelFormat use them. We can
not recognize these format and pass a NULL pointer to
gst_vaapi_surface_new_from_formats.
We need to add a pointer check here and let the fallback logic handle
this case correctly.
Other drivers work well.
Improve the mapping between va format and gst format. The new map
will be generated dynamically, based on the query result of image
format in VA driver. Also consider the ambiguity of RGB color
format in LSB mode.
We no longer need this obsolete set_property function now after
switch to standard gobject's property manner.
Also delete the old encoder's property enum in the header file.
G_PARAM_CONSTRUCT make all properties init correctly, we do not
need to init the properties manually.
G_PARAM_FLAG_VAAPI_ENCODER_EXPOSURE is a vaapi encoder specific
flag, means need to expose the property to according encode class.
Install properties for h264 encoder fei class. Also set the new get/set
property functions for gobject class. Still use the old properties
way now and this new feature will be enabled later.

Replace all gstvaapiobject in vaapi encoders with standard gstobject.
Let the gstobject common logic to handle all the init and finalize
works. But the property install/set/get still use the old way, need
to be improved later.
The context overlay was an optimization to apply a video composition
to all the surfaces bound to a context.
But since commit 18031dc6 this optimization was disabled, so it is
better just get rid of it.
In commit 18031dc6 surface's parent context is not assigned because of
circular references. Since then (2013), there's has no issue with
subpictures attached to a context, the current only users of this API.
This patch cleans up all of related code with the unused surface's
parent context.
This code doesn't define the profile used by the internal encoder, but
it used to "predict" which is going to be used and to get the caps
restrictions.
Before the profile was predicted by checking the donwstream caps, but
sometimes they are not defined, setting an unknown profile. In order
to enhances this situation, the encoder asks to internal encoder if it
has one. If so, it is used.
To ask the internal encoder's profile a new accessor function was
added: gst_vaapi_encoder_get_profile()
The return value of vaGetConfigAttributes() of VAConfigAttribRTFormat
is a bitwise flag with *all* the supported chroma types.
Previously it was assumed that the return value was a single value,
thus when returning the GST_VAAPI_CHROMA_TYPE_XXX the code was a
simple case. But it is wrong.
This patch changes the case block with a sequence of ifs testing the
bitwise. For now we assume a "priority" list in the testing sequence.
