            Bug ID: 768264
           Summary: amcvideodec: Expose non-GL formats on Lollipop+
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: minor
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: olivier.crete at ocrete.ca
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Before Lollipop, the only way to know which format a decoder would decode into
was to start decoding, and then just before getting the first frame, we could
get the format. Since Lollipop, you can get the output format by just doing a
configure(), this only requires the mime type of the codec and the resolution.
I've tried just using 640x480 as I assume all machines should do that. The
second assumption is that the output format is the same irrelevant of the
resolution. This also means that although a decoder can in theory output many
formats, we can know exactly which one it will output for each input format.

Just as I'm attaching the patches, I'm thinking that maybe we should also move
the gl_output_only flag to be per input format.
