            Bug ID: 774991
           Summary: RFC: entatransform plugin
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---

Vivante 2D GPUs feature a video rasterizer that is able to scale frames or to
transform frames between certain pixel formats using a filter kernel.

The created the etnatransform plugin, which allows to use the video rasterizer
via the etnaviv driver in Gstreamer pipelines.

The current plugin basically consists of code that was copied together from the
xf86-video-armada driver (filter kernel) and the etnaviv tests in libdrm and
repackaged to be usable as a Gstreamer plugin. It is not really well tested,
would benefit a lot from some refactoring and modularization, and contains some
crude workarounds.

It is not ready for inclusion in Gstreamer, but maybe someone finds use for it.
