           Summary: androidmedia: Zerocopy decoding potentially slower
                    than before due to missing queueing

To solve this we should implement handling of OES textures in libgstgl instead
of converting inside the decoder. That way we can have multiple textures queued
up to allow smooth playback.

For example with my phone currently, decoding is fast enough on average but
very bursty. Some frames take twice the time they should, some frames come out
of the decoder together at the same time as other frames.
