I have a problem running out of CPU power with mplayer. We are pulling MPEG Transport Streams from a V4l frontend, decoding them, and applying the video scale, crop, and expand filters to fit (and normalize) the output to the "TV Screen" portion of our display. All of these operations are running on one core of a Cure Duo, and dropping frames/complaining about "too slow"/..., while the other core is 90+% idle. It takes about 8% of one core to fetch a sample TS from the frontend, about 40% to do the MPEG decode, and 60+% (not sure how much more) to do the scale/crop/expand filtering. If I could move the video filtering to the unused core, I might be able to handle the streams, or, at least, determine that I don't have enough aggregate CPU power. I have looked through the manual, and only a few things explicitly support threads. I tried the lavdopts threads, but that gave me a garbage screen with what looked like multiple processes writing to the display simultaneously. Does mplayer currently support separating the MPEG decoding and video filtering to different CPUs/cores? If so, what options, either on the command line or in "config" do I need to activate them?
