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. > When my 512x288 at 29fps mp4 video is scaled to full wide screen, > the video details are lost as well as is overall viewability. 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. > It chops the audio into short blips while individual video frames take 5 or > more seconds to load.

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.
