            Bug ID: 764201
           Summary: Provide fast path for I420 to BGRA (and/or RGBA)
                    conversion and back
    Classification: Platform
           Product: GStreamer
           Version: 1.8.0
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-base
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: alex.s.pevzner at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Need a way to have a faster conversion from I420 to BGRA/RGBA and back --
ideally, to match the performance of ffmpeg's swscale.

Opening per conversation in

It seems like there's a related issue opened already (734003), but opening this
request anyway, since it's potentially a superset (or there could be a non-Orc
based solution).
