As some libav encoders (such as MPEG2) use a thread_count parameter to control how many threads to use, and since it was always being set to 0 (which uses the default), suboptimal threading can sometimes be chosen. This extends the libav encoders to allow for a max-threads parameter which is passed into the internal structure to control this knob if applicable to the encoder. https://bugzilla.gnome.org/show_bug.cgi?id=726612
