    recorder: Port to new gstreamer vp8enc api
    
    The speed and quality properties have been removed in favor of properties
    closer to the upstream library.
    
    Removing the properies from the pipeline would result into a huge
    slowdown so we have to map the old values to the new ones.
    
    According to the source code of the old vp8enc element quality maps to
    (int)(63 - quality * 6.2) for min_quantizer and max_quantizer, while
    speed maps to cpu-used = speed == 0 ? 0 : (speed - 1).
    
    So set min_quantizer and min_quantizer to 13, and cpu-used to 5 based on
    the above formulas.

         for a guess at the optimal thread count on the system.
