Linux Applications / Mplayer Development And Optimization For Arm
« on: November 13, 2007, 05:38:08 pm »
Just a quick update from me, mostly of interest to the angstrom people...
You may remember I hacked mplayer/ffmpeg to actually use iwmmxt rather than just compiling them.
I got VC times of apx 43 seconds for the doom clip running on angstrom.
Now I am using *the same binary* and get VC times of 37 seconds on the latest Angstrom test images, so something has changed, maybe cache support or iwmmxt support in the kernel. Anyhow, my results are now about the same as my tests on cacko with attys mplayer.
If I use the default mplayer included in the angstrom iwmmxt feeds, I see VC of 52 seconds. I'm going to take a look, and try the svn version.
Cheers,
Tim
