3398c64036 libs: encoder: set entrypoint based on tune automatically
Some profile, such as H265_MAIN_444 on new Intel platform, may only
support ENTRYPOINT_SLICE_ENCODE_LP entrypoint. This leads two
problems:

1. We need to specify the tune mode like `vaapih265enc tune=low-power`
   every time when we need to use this kind of profile. Or we can not
   create the encoder context successfully.

2. More seriously, we set the entrypoint to a fixed value in
   init_context_info() and so the create_test_context_config() can not
   create the test context for these profile and can not get the
   supported video formats, either.

We now change the entrypoint setting based on the tune option of the
encoder. If no tune property provided, we just choose the first
available entrypoint.

b50f06309a libs: encoder: set context info profile by encoder
Instead of init_context_info() setting the passed profile, it is
assumed that it has to be set by each encoder.

f0d6263318 libs: encoders: use GST_PARAM_USER_SHIFT to define internal params
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.

1c73dc969c libs: profile: add gst_vaapi_profile_get_va_name()
gst_vaapi_profile_get_name() returns a proper name for
GstCaps. Nonetheless, there are many profiles which don't have a name
representation for that realm.

gst_vaapi_profile_get_va_name() returns the name of the profile
according to its VAProfile name.

This new funtion is used in the encoder error message.

5b1fe9c68a libs: encoder: h264,h265: Set max_qp if min_qp is non-zero.
media-driver currently fails to set a correct value of max_qp when

This patch sets max_qp to an arbitrary value to avoid this output
temporary.

220016aa6c libs: encoder: h264/h265: flush pending ordered pictures
In order to flush the pending pictures, a new internal encoder vmethod
is used: get_pending_reordered()

This method follows an iterator pattern which will return the next
picture to encode and push.

The base encoder will call this function in a loop when flush() is called.

For now, only H.264 and H.265 encoders implement this flushing mechanism.

aa6aa996d6 libs: encoder: h265: add multi reference support
This is doing the same as h264 encoder as the following:

Using num_ref_frames provided and the result of the Query
VAConfigAttribEncMaxRefFrames, it determines the size of reference list
and perform encoding with multi reference frames as the following:

1\ The num_ref_frames is being considered as the number of
reference picture list0
2\ Encoder adds 1 reference frame more to the reference picture list1
internally if b-frame encoding.
3\ If num_ref_frames is bigger than the number of refrence frames
supported in the driver, it will be lowered.

Also this patch includes:
- Set num_negative_pics and num_positive_pics according to the number of
refs.
- Set delta_poc according to the number of refs.
- Increase max_dec_pic_buffering according to the number of refs
- Change max_num_reorder_pics according to num of bframes

If the value provided is bigger than the number of refrence frames
