We want to collect some money for Altivec Mplayer optimization.

We have a programmer for it. We need 805 Euro for the programmer

- it is risk for all Altivec owners,no guarantee of a speed advantage
- goal is that Prometheus h 264 1920x1080 works on a X1000
- goal is speed advantage on PAT6
- goal is speed advantage on every Altivec Amiga like G4
- goal is speed advantage on G5 (MorphOs)
- OpenSource

Planning to donate some...
(I do not have Altivec on AOS4HW, but I do on Morph HW)

Perhaps, AFTER Altivec version is DONE, the author could look at DSP instructions of PPC440&460 to see if they are usefull for speeding up video.

btw: "Prometheus h 264 1920x1080 works on a X1000 "

So, the latest RadeonHD drivers do not give enough acceleration?
Or is mplayer lacking the support to use RadeonHD drivers fully?
Or is this JUST meant to be a more generic solution.


Does dvplayer have nowdays RadeonHD + Altivec accelerations?

what does the "no gurantee" Thing mean?
If it Fails the Money is gone anyway?

Just look at this:

The radeonHD drivers give an enormous speed up to displaying videos, codecs such as mpeg2 where the main bottleneck is display run much much faster, over 40fps at full 1080p HD.
However the H264 codec achieves very high compression rates, (which is great for low bandwidth streaming) and so decompressing takes lot of CPU power, so some H264 encoding schemes don't quite make it on even on an X1000 with Radeon 2.4 drivers and a fast card.
