HD Video Codecs for Nokia N900?
 

Hey guys,
Does anyone know if the N900 will ever support 720i HD video? The screen is well better than Samsung Omnia HD resolution by far. And yet the same hardware in term of graphic and CPU.

This should be possible to play without a problem, If the Omnia can why can't N900?

I really hope the Video recording has better functionality just like the Omnia HD. Time laps, slow mo and as for the photo camera, smile detection and all this candy bonus would be very blessing.

Don't you guy ever think this would be the great idea for N900?:D

Re: HD Video Codecs for Nokia N900?
 

Why you need a higher res-video, when the Screen outputs a max. of 800x480...

Re: HD Video Codecs for Nokia N900?
 

I suppose there is nothing stopping the community from doing this.
It just needs someone to take ownership of something and start coding.

Have you tried using mplayer?
(It's available in the repositories but mplayer is a command-line app. You have to be comfortable using the terminal)

I don't use the included media player for watching video anymore! go straight to mplayer instead.

Samsung Omnia HD = 360 x 640 px

Re: HD Video Codecs for Nokia N900?
 

uncle.sam, I know that, but N900=800x480

Re: HD Video Codecs for Nokia N900?
 

It would be 720p, not 720i if any. (wiki) and as said it would be inefficient. You can just use a high bitrate with 800x480. That would be the maximum.

We need a way to be able to play HD content, scaling down their resolution on the fly, with video acceleration.

The only way to do it right now is by using mplayer with the software scaling.. of course that is very slow.

If I try mplayer with -vo xv, it can't scale down video that is larger than a certain resolution, ie it can't scale down 720p

Re: HD Video Codecs for Nokia N900?
 

True true true.. I'll just wait for it to come

Re: HD Video Codecs for Nokia N900?
 

there will never be HD on this device. period.

Re: HD Video Codecs for Nokia N900?
 

I can't honestly figure out why people would want HD support on the N900..

The ONLY time you'd be able to take advantage of it would be in some sort of streaming situation where you were streaming HD content from the device to a display that could support it.. but wait.. you can - in effect - already do that, so honestly, what's the deal?

As has been said many times over, the display on the N900 can't show you HD content, nor can the TV-out cable, so WHY would you want to bother with having the CPU/GPU work overtime downscaling it on the fly? I think you'd probably get better picture quality using a dedicated app like Handbrake to do your downscaling than having it done on the fly. You'd certainly get longer battery life.

Is it just for the convenience of not having to re-encode your HD content before you can watch it on the N900? I just don't see any other reason..

Re: HD Video Codecs for Nokia N900?
 

That's a big reason for me, plus I'd like to see what they would like on my N900.

Re: HD Video Codecs for Nokia N900?
 

720p video works flawlessly on the pandora (same hardware) so I don't see why the N900 wouldn't be able to playback 720p files...

I'll look into that next week.

Re: HD Video Codecs for Nokia N900?
 

to be honest... video performance (right now) sucks very hard.
i don't need HD-playback because the screen resolution isn't even HD (800 * 480) as mentioned few times before.

but what's driving me crazy is the fact that i have got many .avi and .x264/.h264 videos created as a compromise between resolution, bitrate and of course filesize.
so mostly they have around 700 * 350 px and between 1200 and 2000 kbps on video-side and around 300 kpbs 5.1 ac3 on audio-side.

i tested to remove the audio completely to see if afterwards the performance isn't that bad anymore. but audio doesn't seem to be this important for bad/good playback.

i have to say that most of the .avis are playing just fine but it's horrible to see the .x264 lagging around with the audio playing normal speed and the video getting more and more way behind in every second of "watching" this.

in my opinion my video-encodings with the settings mentioned above should play smooth on a device like the n900. there is some work to do - especially for the built-in player on nokia's side.

Re: HD Video Codecs for Nokia N900?
 

That's one reason, HD being a marketing word being the other.

Re: HD Video Codecs for Nokia N900?
 

to anyone not wanting to reencode HD content - Knots 2 is no solution for you?

and regarding the Omnia HD - it's just about the buzzword.
it doesn't do HD on the screen, it can push 720p content via DLNA to a suitable player, but even that doesn't work as advertised:

Re: HD Video Codecs for Nokia N900?
 

mhm... not really, sorry...

i want to have my videos (and they aren't hd but playback doesn't work smoothly as it should be anyway...) on my phone. i want to have them with me everywhere i go. therefore streaming is fine at home but no solution for the weak video playback of the n900...

Re: HD Video Codecs for Nokia N900?
 

actually, i don't consider the video capabilities of the N900 weak at all. i've thrown files >1 GB at it, and didn't notice any lag whatsoever.

the occasional video won't work or start to stutter, but those are usually files in a strange encoding format.
i see it as a kind of screening process - files that don't play on the N900 are usually encoded so badly that it does make sense to reencode them :)
but maybe i'm just lucky that most of my vids are encoded well ;)

Re: HD Video Codecs for Nokia N900?
 

file size doesn't matter. the file could be 10GB large and played without any problems. ^^

mhm... i would say that my videos are encoded very well. they even look good on a 42" full-hd with that (actually) low resolution.

that's the point ;)

avis play very well on the n900, but the specs state that the n900 should play h264 videos as well. and yeah... equal resolution, bitrate.... all the same... but avis play smooth and h264 doesn't...

ok... the codec does more compressing etc... and therefore the playback needs more power... but i can't understand why my files are lagging... :/

Re: HD Video Codecs for Nokia N900?
 

maybe that's the problem. some codecs use a lot of post-processing to eliminate artifacts for upscaling. i imagine such a codec isn't suited for this device.

Re: HD Video Codecs for Nokia N900?
 

Personally, I'd be very interested in such codec, especially if I could play with them with gstreamer. I'd also be very interested if I could send HD out the video port. With that, I would be interested in exploring if an n900 could function nicely as a Roku like device.

Re: HD Video Codecs for Nokia N900?
 

i like to say it again (and again... and again...):
the display resolution is only 800 * 480 pixels.
so higher resolutions won't bring any advantages - on the contrary: it will only suck your battery even faster. ^^

video port is only PAL / NTSC. with the specific resolutions.

Re: HD Video Codecs for Nokia N900?
 

Seriously we want HD recording. I don't care about the screen resolution. I care about the output video resolution. We need this.

Re: HD Video Codecs for Nokia N900?
 

pls help me.......

Re: HD Video Codecs for Nokia N900?
 

yes you can play high quality HD MKV VIDEOS.....after a some efford i found the maximum quality that u can play in your n900(quality was amazing to me)....here are the steps


1) install the extra codecs for the media player ...u will find this in file manager ...install it first


2)download the converter called "Any DVD Converter Professional" or if u have this then fine you can start


3)if you have any 720p or 1080p MKV high quality videos ...then use one the video to start to convert ...


4)in Any DVD Converter Professional first click on the "Add video" icon and add your highest quality MKV video...then in right side under the output profile ....there is a dropdown button sellect "video files" and also there is an another drop down button beside of that from there you have to sellect "Matroska Movie(*.mkv)"

then look right side down....there are some options to set
in video options sellect video options as"mpeg4" frame size as"800*480"(if its not available type it manually)...video bitrate as(4000)if u increase more than 4000 picture quality will get increased more and more....video frame rate as 30


in audio options select audio codec as "Mp3"(pls dont select any other it wont wok)....audio bitrate as 320....and sample rate as 48000

finally inorder to make your video full screen there is one more setting....go to edit->options->video under "Video Resize" make sure to tick Fit to height and Expand to Frame size boxes...


thats all u need to do just convert and enjoy the Tru HD in your n900.....remember here you r playing the mkv format not the mp4 bcos n900 is capable of playing MKV by doing thsese conversion..


i hope this will help the guys whoever have N900 and desire to play eye catching HD vido playback

Re: HD Video Codecs for Nokia N900?
 

Hey is that using the baseline profile? The N900 can only handle the baseline "low-level" profiles...and most of the encoding gurus who deliver our hd content via a certain swedish portal use high-level profiles. Which, honestly, is the whole point of .264: lower bitrate, higher quality, screw the battery...

i find it easier to just re-encode my hd stuff in 800x4xx / mp4 / QF=2. Works out quite well, at pretty much the same bitrates you've mentioned up there, no complexity involved...

Re: HD Video Codecs for Nokia N900?
 

It does? any links? What are they using, mplayer? VLC?

I was under the impression they were on the same level as we are.

That said, I've never had any problems with watching movies, I've got mostly high compressed h264 or 640x480 avi's. For my more difficult codecs (some anime and odd re-encodes) I can overclock to 950MHz and never see studder.

I can appreciate the convenience of not having to re-encode from HD formats, but its worth it to avoid even the occassional studder and battery issues of more demanding videos.

Has everyone here tried kmplayer or SiB for their videos? Fantastic GUI frontends for mplayer.

Re: HD Video Codecs for Nokia N900?
 

After all the downsampling, resizing and transcoding it would be a stretch to call the result "HD" video.

Re: HD Video Codecs for Nokia N900?

And use HandBrake with the provided preset-file to transcode videos to N900.

Someone suggested using mplayer. mplayer does not have hardware accelerated decodecs, so it is not as optimizied as the default media player which has DSP-optimized gstreamer-plugins for some codecs and for some (baseline) settings.
