Changes (by jkqxz):

 * status:  new => closed
 * resolution:   => invalid


 This is an expected consequence of the single-threaded nature of the
 ffmpeg utility combined with synchronous behaviour in the Intel VAAPI
 driver (it doesn't use the CPU while encoding, but it still blocks the
 calling thread waiting for it to finish).
