Using a ordered ring buffer and a thread pool, the color space conversion is not multi-threaded based on frames. I tried to implement slice based threading, but libswscale did produced highly distorted pictures without obvious reason. This approach introduces some more "lag" when decoding and skipping, but shouldn't be affect the user negatively, since movie watching is not lag sensitive, as long as the A/V is synchronized. Change default to software decoding. SW decoding is the most robust and fasted method of decoding right now. Users should enable hw based decoding if their system requires it and it's actually beneficial for them. Fix deadlocks when seeking and decrease RAM usage. Decrease memory allocation by reusing AVFrames.
