Re: H.264 playback

[drfredc]

While poking around the tableteer info, I ran into a chart of supported media 
player video file formats.  There are significant limits to frame size of 
various video formats.  Native video on higher end camera video is out of range.

The quality of HW scaling on N800 is excellent (bicubic according to S1D13745
TV-Out Mobile Graphics Engine product brief), so I don't think you would lose
many video details. Also scaling is performed by hardware and does not consume
any extra cpu resources, so there is no reason not to use it.

While H.264 has a good potential for ARM11 optimizations, mplayer does not
have any of them yet and I don't have any plans for adding such optimizations
for my own reasons. And AAC audio decoder is not properly optimized for ARM
in mplayer either. So using mplayer to watch H.264+AAC videos is not a very
good choice right now.

By the way, ARM has released some H.264 and AAC optimized libraries 
recently: http://arm.com/news/18441.html
Who knows, maybe Nokia can use them in one of the next N800 firmware updates
to provide H.264 video support in the built-in media player.

Re: Canola never finds any media

[drfredc]

Good for you!  You probably had all the other stuff it needed loaded.  On my 
fresh unit it installed but I couldn't get it to read anything I'd on my unit 
and there weren't any instructions on how to access this most basic of data.   
JUNK!

Junk?

Canola is one of the best apps around for pdas...let alone the N800.

I had no problems when I installed and it works perfectly.
