-// TODO: We use x264's “speedcontrol” patch if available, so that quality is

 // The encoding threads are niced down because mixing is more important than
 // encoding; if we lose frames in mixing, we'll lose frames to disk _and_
 // to the stream, as where if we lose frames in encoding, we'll lose frames
 // to the stream only, so the latter is strictly better. More importantly,
-// this allows speedcontrol (when implemented) to do its thing without
