ed3360bf3b libs: encoder: check for maximum number of slices
Right now, H264 and HEVC can set as a property the number of slices to
process. But each driver can set a maximum number of slices, depending
on the supported profile & entry point.

This patch verifies the current num_slices to process against the maximum
permitted by the driver and the media size.

4f343f82e3 encoders: add quality level tuning
This patch adds the handling of VAEncMiscParameterTypeQualityLevel,
in gstreamer-vaapi encoders:

  The encoding quality could be set through this structure, if the
  implementation supports multiple quality levels. The quality level set
  through this structure is persistent over the entire coded sequence, or
  until a new structure is being sent. The quality level range can be queried
  through the VAConfigAttribEncQualityRange attribute. A lower value means
  higher quality, and a value of 1 represents the highest quality. The quality
  level setting is used as a trade-off between quality and speed/power
  consumption, with higher quality corresponds to lower speed and higher power
  consumption.

The quality level is set by the element's parameter "quality-level" with a
hard-coded range of 1 to 8.

Later, when the encoder is configured in run time, just before start
processing, the quality level is scaled to the codec range. If
VAConfigAttribEncQualityRange is not available in the used VA backend, then
the quality level is set to zero, which means "disabled".

All the available codecs now process this parameter if it is available.

3532dca16a libs: encoder: h265: chroma and luma with format
If the profile is main-10 the bit_depth_luma_minus8, in the sequence
parameter buffer, shall be the color format bit depth minus 8, 10-8
which is 2. Also for bit_depth_chroma_minus8.

This patch gets the negotiated sink caps format and queries its
luma's depth and uses that value to fill the mentioned parameters.

48e21d6ba8 libs: encoder: h265: ensures profile given format
Set the VA profile as GST_VAAPI_PROFILE_H265_MAIN10 if the

Otherwise, keep GST_VAAPI_PROFILE_H265_MAIN

7f8b325450 libs: encoder: h265: remove unused macro definition
Since the h265 encoder doesn't use GValueArray, there is no need to
disable the Glib deprecation warnings, thus removing the macro
definition.

9ed6ac1f76 libs: h26x: adds gst_vaapi_utils_h26x_write_nal_unit()
Implements gst_vaapi_utils_h26x_write_nal_unit(), which writes NAL
unit length and data to a bitwriter.

Note that this helper function applies EPB (Emulation Prevention
Bytes), since otherwise produced codec_data might be broken when
decoder/parser considering EPB, starts parsing.

See sections 7.3 and 7.4 of the H264 and H264 specifications, which
describes the emulation_prevention_three_byte.
