Encoder loopfilter running in its own thread In multithreaded mode the loopfilter is running in its own thread (filter level calculation and frame filtering). Filtering is mostly done in parallel with the bitstream packing. Before starting the packing the loopfilter level has to be calculated. Also any needed reference frame copying is done in the filter thread. Currently the encoder will create n+1 threads, where n > 1 is the number of threads specified by application and 1 is the extra filter thread. With n = 1 the encoder runs in single thread mode. There will never be more than n threads running concurrently. Change-Id: I4fb29b559a40275d6d3babb8727245c40fba931b
