    Bring back slice-based threading support · 6f221210

    Enabled with --sliced-threads
    Unlike normal threading, adds no encoding latency.
    Less efficient than normal threading, both performance and compression-wise.
    Useful for low-latency encoding environments where performance is still important, such as HD videoconferencing.
    Add --tune zerolatency, which eliminates all x264 encoder-side latency (no delayed frames at all).
    Some tweaks to VBV ratecontrol and lookahead (in addition to those required by sliced threading).
