Thanks, but all those post... end in nothing specific....

Is there any developer making this possible? Like many people i think, the nokia n900 is capable to record&play HD content ( 1280x720 )

And the camera is a bit bad to be a Carl Zeiss lens

I doubt this (720p hw accelerated decode) is possible without support from Nokia or TI.

It is capable, at least the hardware is.

Here are some specs from the OMAP3430 product page :

You do not need support from Nokia or Ti to get 720p working, overclock and install VLC player and you will have 720p simple as that.

It's not the video resolution that matters; it's bitrate. I bet you can play 1920x1080 videos smoothly on N900, provided its bitrate is only <=400kbps :P

Or overclock ( I'm running at 1150MHz ) and install mplayer.

It works for me.

And watch a movie at 720p with 1.15Ghz clock speed then the N900 died after 40minutes of the movie duration. That is awesome! lol

I am thinking that you could do pretty much the same thing on any phone. Batteries are

a) small capacity
b) have not kept pace with the tech

Why do you need to oc so much. I oc to 850 ulv and generally 720 runs just fine.

Ok, ok, I know you're going to hate me for saying this, but yes -- I do "waste" time converting videos. Ever since I found Handbrake, I love having the ability to let my desktop computer spend time and effort optimizing videos for playback on my handheld devices, customized to their exact resolution, rather than forcing them to muck around with real-time conversion of data. You can get a better quality of video and much smaller file sizes; what's not to like?

I sometimes do store 720p or 1080p videos on my N900, but that's for when I plug it into the USB port of a device with sufficient screen real-estate.

You will get worse quality by re-encoding, not better.

If I download a video from internet or load it directly from my camera with HEN for example, I don't have even option to re-encode it with my computer..

And the size of video doesn't matter that much with device which has 32-64 GB internal storage and support 3 TB external storages

I tried to run ~0.43 MB/s x264/AAC/MKV 720p video from eMMC with VLC 1.1.5 and I only got the first frame :/ My CPU is running at 900 Mhz.
