Work around slow decoder/converter issues
Since our VPU can't decode to a format anything MDP can understand
decoding a frame consists of 2 steps, decode and convert. Performing
both operations in the same thread context serializes operations,
nothing is decoded while something is converted and vice versa.
Add a queue to decouple thread context and allow both steps to
execute concurrently.
Fixes some errors of the kind
"There may be a timestamping problem, or this computer is too slow."
