I read the following statement from another message board...is the statement true? I am very interested to know. Is it possible for the N810 to improve (30 fps 800x480) on the video decoding function?

"At the risk of being wrong, I'll sum-up what I think I've heard here over the years and hope others will correct/clarify: The OMAP in-built video support doesn't go up to the 800x480 resolution of the Internet Tablets. Therefore, Nokia used external graphics chips from Epson. The 770's chip works up to it's design bandwidth for video. The N8xx chip has a bug causing tearing at design bandwidth, so its video resolution and/or frame rate must be artificially limited."

Like you, I've read that the N8X0 uses a external LCD controller, since the onchip one is limited to 640x480 (I think). And the connection to the external controller is too slow for full framerate, full size video (800x480 @ 30fps).

That said, it's never been a problem for me because the video decompression step is usually the bottleneck in video playback.

In the future, better optimized video decoders may move the bottleneck to the LCD controller. But I wouldn't hold my breath.

as I understand it in my own limited way, the bandwidth problem with video on the 8x0 is at least partly a bug/design fault, and it would have been too expensive to resolve it since it's in a custom chip.

the bandwidth is sufficient to play a lesser resolution video which can be scaled to full screen. I find that if I transcode a PAL DVD (720x576) to 320x240 or 400x240 (widescreen) at 960kb/s 15fps it looks fine when the video doubler scales it up - more than sufficient to watch a movie on the go. FYI, the script I use is here:

Note that the scaler does its business on the LCD controller chip, so only the smaller resolution video needs to be passed through the bottleneck.

This is feeling like a Zaurus meeting.
I have also recently found that 320x240 works well streamed over WiFi from my Samba share too.

Or maybe like one of the many video threads at OESF...

On the rare occasion that I want to watch video on one of my mobile devices, I encode it to 320x240, which looks decent and plays well on just about everything.

I use the tablet-encode.sh script at best + 2-pass encoding for my stuff, which encodes at 400x224. Quite good. Wish I had that when I was still using my Z .

I can get 640*360 to run smoothly in the tablet
