I had a request for a newer version of mplayer with multithread support (using more than one CPU-core). This allows to play HDTV videos on multicore computers, where other players fail (too slow). I was not able to compile the latest svn version with the ffmpeg-mt libs, but found working sources here: http://nikita.melnichenko.name/download.php?q=mplayer-mt-20091127.tar.bz2 This topic explains it: http://nikita.melnichenko.name/blog.php?id=5&topic=gentoo-ebuild-mplayer-mt&lang=en I finally compiled it with support for 8 cores:
So we get this result:
I compiled with support for Nvidias vdpau accelleration (includefiles from driver 180.44). However I could not test vdpau, as I actually use a Ati-card. I have read that you cannot use vdpau AND mt, just vdpau OR mt. You can run the player from the multimedia menu, also a second one, that uses the unaccellerated "x11" extension, but scaled up to fullscreen (this required some special commandlineoptions, as x11 itself is not able to scale). The required libraries I placed in /usr/lib/mplayer-mt-libs/ to avoid conflics with your existing libraries. Mplayer is launched by customized scripts, to use those libs, and to play files using two cores. If you would use 4 cores, you had to modify the gmplayer-mt or mplayer* scripts in /usr/local/bin/. The value to set the cores is:
If the vdpau video does not work, try:
You can activate vdpau or other video-output drivers with a right-click on the player -> Preferences - video x11: no accelleration xv: accelleration supported by many cards (default) vdpau: supported by newer nvidias (using the commercial driver 180 or newer) gl, gl2, XvMC: best results on some cards If you get no sound, try to change the preferences in "audio", usually alsa or oss will work. Download (6.5 MB, 15 MB extracted): http://dotpups.de/puppy4/dotpups/Multimedia/Mplayer-MultiThread/mplayer-mt-vdpau-theora-2009-11-27.pet Some skins are included. I tested it in Newyearspup02, Puppy 4.3, and Fluppy005. It was compiled in Newyearspup02 (extended 4.1). If you have a infrared device for your computer, it should work, but I think you will need the lirc pets from tempestous in this thread: http://www.murga-linux.com/puppy/viewtopic.php?t=26511 To verify, that really 2 cores are used, you can run in a consolewindow "htop" from: http://www.murga-linux.com/puppy/viewtopic.php?p=234430 Hint: if you play low-res videos on a 52'' HDTV-TV, invoke the player by such a script:
This will scale and sharpen the video, but you need a fast processor. Mark

I re-uploaded the pet, added the option "-really-quiet" to gmplayer-mt to avoid messages if a video throws warnings, and enabled postprocessing in the options. Some *.mpg videos refused to play before, now they seem to work. This seems to be an issue of gmplayer only, not mplayer? Mark _________________ my recommended links |

Thank you very much. I am afraid it can't play WebM and some "MOV". The audio is not played in these videos "Hedgehog3gp" and "Macimp4". Streaming Video Codec Test Clips zip WebM Test video: http://lachy.id.au/lib/media/elephantsdream/Elephants_Dream-360p-Stereo.webm from: Custom controls WebM video. _________________ adobe flash is rubbish!
