Re: 720p video on G4?
Hello all:
Sorry for delay; I'm away for my e-mail last days.

This video could play in AMD Athlon 1500+ with 4+ years old, I think my
G4 is powerfull that it.
I'm afraid that while in theory the performance of these CPUs may be
about the same, in practise the Athlon machine still has several
advantages:
* Due to x86 being more popular, its code is probably better
optimized, in particular but possibly not only for the SIMD
extensions.
* It probably has significantly more memory bandwidth, not only
because it's a desktop vs. a laptop.
* ...
Ok, I'm afraid that a future better optimized code for PowerPC isn't
posible due minor desktop-laptop user since Apple is out; Do you think
about? (I supposed that it's needed a high skill in program and PowerPC)
Also, the X driver version / configuration may also matter. Make sure
you're using xserver-xorg-video-radeon from sid and that the DRI is
enabled.
I'm using:
ii xserver-xorg-video-radeon 1:6.12.2-3
X.Org X server -- ATI Radeon display driver
ii xserver-xorg-video-radeonhd 1.2.5-1
X.Org X server -- AMD/ATI r5xx, r6xx display driver
Did I need only "xserver-xorg-video-radeon"?

Something to adjust better?
I'm using "xv" output in mplayer (in answer to José Jorge).
Anyone can play 720p videos on Powerbook G4 or similar?
Some 'simpler' 720p videos play mostly fine on my PowerBook5,8 (very
similar to your PowerBook5,7), but not a chance for 'more complex' ones.
I assume 'simpler' vs. 'more complex' is a lot due to the bitrate of the
video, but there may be other factors.
Do you have a link to some "simpler" video, I want to try in my machine.
Do you think that compiling mplayer is a good option? Need a specific
library?
I doubt there's a lot to gain compared to mplayer-g4. IME sometimes a
video will play better in one player or the other, but it sounds like
you've already tried that.
Yes, I'd tried with Kaffeine, Mplayer, VLC and Dragon Player; Totem
isn't in the list, perhaps I should try with it too...
Thanks for your time and responses.
Salud y Revolución.
Lobo.
