720P playback! Samsung H1/ Omnia HD can, why N900 Can't??? i can't find anything relevant... ( i searched )

My 3 last phones OmniaHD > Samsung H1 > Motorola DROID > Nokia N900.

All this phones have the same CPU

OmniaHD = Omap 3430
Samsung H1 = Omap 3430
Motorola Droid = Omap 3430

and obbiously, nokia N900.

All these devices can play successfull a 720P files, ( samsung H1 the best of all )

But why nokia N900 at the same speed, can't?? maybe the codecs, or maemo??

PLEASE DON'T SAY, why you whant to play a 720P if the resolution is 800x480!! i don't care..

YES I KNOW IT, but:
1- I don't wastle time converting a video.
2- sometimes, the movies come in 720P.
3- I prefer to play 720P i can "feel" more detail than standart 480p.

So.... what is the problem? drivers, for sure right? or hardware?

thanks everyone to make this excelent forum.

I don't know about you, but my N900 can play a 720p video smoothly. Even 1080p videos, but not so smooth and only if Keanu Reeves is not acting in them...

Install VLC player and you will get 720p.

The N900 xvideo output driver won't play files with a resolution greater than 854x480. This is not a hardware limitation, but a missing feature, specifically either the N900 firmware doesn't implement the videoscale GStreamer plugin, video scaling is not implemented in the OpenMax IL layer in the DSP video codec or this functionality is implemented and is just not exposed in the xvideo driver.

You can always use mplayer to downscale your video but since it's not hardware accelerated it's going to be slow. Example :

mplayer -sws 0 -vf scale=800:-2 video.file

why the developers doesn't try to implement it???

I think the same with the 720P recording ( not 100% sure than 720P playback )

Here in this forum, the developers are doing anything? or maybe on another N900 forum??

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

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

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. :)

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.

If you mean that a video with a native resolution of 800 by 480 pixels is inferior to a video with a native resolution 1280 x 720, then yes, I agree with you, but only when you display them at their native resolution. If you're trying to say that squashing a 720p video down into an 800x480 screen in real-time is more effective than taking your time and re-encoding it using a system that gives you fine control over the bitrate (such as handbrake), I can't see how that could possibly be true.

Perhaps you don't have the right software? Much (maybe most) of what I re-encode is video off the internet.

Lugging around external hard drives kind of negates the whole purpose of having a portable media player, doesn't it? I'd much prefer to squeeze more data onto my micro SD cards than be forced to juggle little hard drives around.

Re: 720P playback! Samsung H1/ Omnia HD can, why N900 Can't??? i can't find anything relevant... ( i searched )

The problem is that the N900 uses the OpenMax IL standard to interface with the OMAP3430's DSP. The OpenMax IL standard only allows one to control and connect "components" ( eg. video codecs ) in the manner that Gstreamer does that run on top of the DSP hardware -- it does not allow the user to interface with the DSP directly. If you want CPU agnostic portable access to DSP functions then the DSP vendor needs to implement the OpenMax DL or "Development Layer." Unfortunately, TI, in the interest of maintaining a stranglehold on companies that are paying big bucks for TI's DSP development tools and NDA licenses for access to said software and hardware, has locked down direct access to their DSPs. The only full Implementation of the OpenMax DL standard that I know for ARM is software based.

See : http://www.arm.com/community/multime...dards-apis.php

You have to register to download the Cortex A8 NEON optimised libraries.

There would be no speed advantage; in fact there would be a major hit to performance as these these libraries are software based. Also, one would have to rewrite all the codecs that used to run on the DSP, but there are already implementations of software based A/V codecs that are optimised for ARM's SIMD media instruction set, namely NEON. The main open source implementation is the ARM port of FFmpeg ( now known as Libav ) .

The libraries I mentioned just make implementing such software codecs easier.

Here is betaversion of PanPlayer, player for Pandora console, which has similiar hw like N900 and running Linux.
http://dl.openhandhelds.org/cgi-bin/...,0,0,0,114,329
This player uses partly DSP, whis is the same like at N900. It is able play videos with higher resolutions then 840x480 (yes, Pandora has the same).
So.. can this be answer? Is it possible port to N900?

Binary version. Extract to directory, cd to directory, then ./mplayer.sh "filename".

Untested because watching films on a screen so small just doesn't cut it for me.

I take no credit for this, it's all JDGBOLT's work.

EDIT: Attempted to test but only getting permission denied repeatedly. Don't have the energy to even attempt this today.

couldn't find library libbz2.so.1. Now same but libmad.so.0. *Sigh* libgsm.so.1.

I have a feeling this won't work, regardless of what I do.

I have compiled libgsm.so.1 for Maemo. Now have another library file to acquire.

I'm gonna need panplayer source.

Do you have mplayer installed? If so, just running "mplayer filename" may use the mplayer and not this new "panplayer" which is also named "mplayer" for the executable. The fact that you cannot play files larger than 864x648 seems to suggest that you are running the "usual" mplayer that we always had on the N900 and not the new one Reffyyyy posted.

I've tried running this panplayer using the mplayer.sh script file it comes with and it always complains about the missing packages that Reffyyyy mentions.
