Do I need to use gstreamer's h264parse to parse the data first and then feed it to gst-openmax or openmax IL layer should be able to handle whatever is being put into the input port of openmax layer by h264 plugin the way it is implemented  now?

>From my experience you usually don't need a parser when you have a
demuxer, but in this case, since the data is raw, you need that. I'm
not sure if decodebin is adding h264parse, but I would try manually
adding it and see if it works.
