Bug ID: 778733
Summary: [gst-vaapi][encoder]Support more encoder quality level
for AVC/HEVC/VP8/VP9 in GStreamer-VAAPI
Classification: Platform
Product: GStreamer
Version: unspecified
OS: other
Status: NEW
Severity: major
Priority: Normal
Component: gstreamer-vaapi
Assignee: gstreamer-***@lists.freedesktop.org
Reporter: ***@intel.com
QA Contact: gstreamer-***@lists.freedesktop.org
CC: ***@gmail.com, ***@igalia.com
GNOME version: ---

The request is about to encoder quality level.As the encoder in VAAPI driver is
improved and more encoder quality level is added for AVC/VP8/HEVC. Now
upstreaming is on-going. here VP9 is ready in driver. The middleware should
support this.

Legacy Encoder at most support two quality level. And new encoder support level
at most 1-7.

Add Encoding Quality tuning [hackish]:

This is a patch to test the encoder quality/speed tuning. It includes few hacks
which we need to remove before pushing.

I am adding the patch here for testing purpose which is basically implemented
for a customer to test the new driver capabilities.

sample pipeline: ... ! vaapih264enc quality-level=7 ! fpsdisplaysink sync=false
video-sink=fakesink textoveralay=false

AVC encoder seems to have progressive quality/speed difference for each quality
level value, but HEVC encoder behaving indifferently :)

Note: Don't push the patch as it is
