Use MPEG4 video codec instead of h264 (avoid h264 until PR 1.2, then N9 might has better decoder) ... I have converted some Youtube files, even with very high resolution and they works well when I have chosen MPEG4 video codec ....

I have used mainly "Freemake Video Converter" and "Any Video Converter", but I think "Mediacoder" is just OK too ...

I have many movies too (unconverted ones) on my N9. All movies works great when MPEG4 video codec is used (it does not matter what file type (folder); mp4, avi, mkv ... and these movies look really great on N9 display ...

What's changed.....

Yes, due to higher DPI, the difference wasn't that great. However, I may also have been blinded by the initial excitement of finally owning the N9. :p

But objectively speaking, SGS2 does have a visibly more crisp non-pentile matrix AMOLED and it's also quite a bit larger. It may not be as bright as the N9 display but after using N9 for a while, I would rather the non-pentile SGS2 screen at that size/resolution/dpi as N9 display just doesn't look as crisp on white texts etc. Maybe I'm just more sensitive/picky but it is visible. Heck, I see the negatives of pentile matrix even on the Galaxy Note with its higher DPI 1280x800 AMOLED display. (although, it is at a higher dpi/resolution which makes it much closer to being it a non-issue)

Thanks to jalyst and jakiman. I prefer Mediacoder more since it has support for embedded subtitles with many subtitle formats , it's quite fast with cuda enandcoding.

Any idea how pr1.2 will improve codec support?

No idea really. I was told they may fix/improve H264 main profile support but nothing beyond that. Only way to know is to sift through the commits in PR1.2 from link below. Might take a while. =P

I don't see why it should be that hard to do, I thought DLNA is just a layer on top of a conventional file transfer protocol. Maybe I'm wrong?
I would think that any DLNA-capable TV is already quite able to do the rendering on its side, no need for the phone to process the data before sending it...
I never said processing was to be done before sending.

Oh yeah of course it's not quite as good in that usage scenario.
But I was speaking from the perspective of videos & most images.
It should be a non-issue there....

Maybe submit a enhancement request in the tracker?
They'll eventually resolve it if there's a solution coming in 1.2 or 1.3.
Otherwise they'll slap a big fat WONTFIX on it...

Can you play any video file which hasn't gone through iTunes in an iPhone? So yes, A4 is more powerfull than N9's SOC but N9 still plays more formats right?

Oh, well, yeah! The closed nature of the iPhone (and, for that matter, most of the "smartphones" out there) is why I ditched my iPhone years ago and have no interest in ever going back. (I would love to see iPhone-like hardware running an open operating system. Heck, I would love to see an iPhone just running OS X for that matter, at least you'd be able to use it to do something useful.)

I registered minutes ago just to post about the codec potential.

I happened to visit http://www.ittiam.com/en/Embedded/Pl...0p-Bundle.aspx (via google search) which states the following:

Quote:

Ittiam's multicore implementation of 720p video codecs on OMAP3 includes a highly optimized IVA only component. The IVA only components are capable of:
  • MPEG-4 SP decode at 720p
  • H.264 BP decode at 720p

Supported by an additional NEON assisted ARM Cortex A8 component, the resultant multicore codecs allow for enhanced video decode and encode performance beyond what can be achieved on the IVA subsystem alone. Examples of codec performance enabled by the multicore architecture include:
  • H.264 Main Profile (MP) and High Profile (HP) decoding at 720p, up to 30fps
  • H.264 Base Profile (BP) encoding at 720p, up to 30fps
  • MPEG-4 Simple Profile (SP) encoding at 720p, up to 30fps

So, this is a software issue anyway and can be resolved given enough dev resource.

So did 1.2 bring improved codec support as was hoped?

We need to look into OC'ing the DSP, heck even the CPU/GPU.
Need to squeeze more out of this baby! :)

Not based on my experience with the PR1.2 'beta' on the N950. In fact, some downloaded 480p YouTube videos that played perfectly in the stock player in PR1.1 now fail in PR1.2 'beta'. I don't know if the final release is any different.

It it still pretty amazing that a Raspberry Pi for 25$ can play 1080p video, and our beloved n9 for 500$+ can't even play base profile 720p smoothly...

DeeGee 2012-02-29 21:26

Re: Video playback epic fail: My N8 plays 1080p My N9 couldn't even play 720p
 
Yeah, that's the unfortunate side of the old OMAP3 chip on N9. Rasperry Pi's cpu is abysmally slow, but it has separate GPU/decode chip that supports 1080p.
And yeah, some videos that worked (badly) on PR1.1, just error on PR1.2.

So much for freaking improved codecs... :(
Hopefully the community will eventually salvage something that we can swap-in.
OC'ing can't come soon enough too....

cm6 2012-03-05 01:27

Re: Video playback epic fail: My N8 plays 1080p My N9 couldn't even play 720p
 
Previously on PR1.1, the video player will try to play any video, even if it lagged or stuttered terribly. Some videos were still watchable.

Now though, on PR1.2, if any video uses > X% of CPU/GPU, it goes...

You can't play these type of files on this device.

It's not a bug, it's a feature.

Use Mplayer & Kmplayer. You can play lots of different videotypes with mplayer and videoperformance is better with mplayer. Of course not "Superbetter" :D

Which reminds me of an N8 -- how difficult can it be to get it all right in one device...
Add a few cm's of silicon FTW :confused:

At least the N9 is available for purchase, the Raspberry hardly ;)

p.s send it from my N900

I found this thread cause i discovered all the videos I transferred from my N8, taken from my N8 are not playing on my N9. I knew it was somewhat laggy on Pr1.1, but PR1.2 changed it to show that stupid message. Like it plays part way and then suddenly the message appears.

Man Nokia, make it so I can play N8 videos at least!

:) nobody knows the actual hardware until it's released it seems anyways :D

Didn't expect a regression in this part... I think the N8 HD videos are not that crazy high anyhow compared to some others. N9 should handle it.

Re: Video playback epic fail: My N8 plays 1080p My N9 couldn't even play 720p
 
Kmplayer+mplayer is a good choice , it still doesn't play properly 720p even at 1350mhz , it plays the video but the framerate is lower , somewhere around 20fps , still better than getting an error like default mediaplayer does .

by the way ... Sometimes the default mediaplayer gives that cannot play error even at 480p videos , something is wrong ...

Maybe a s*** codec , as long as the MKplayer can play 720p videos very smooth just a bit slower . Even with 480p videos the default media player lags .

Video playback a tiny bit jerky after PR 1.2 update!!!!
I have a black version of the N9 16GB (Made in Finland) and all the videos downloaded from YouTube or N8 and snatchy video play!
Playing and downloading video program "CuteTube" and the video is smooth. This video replay on your phone and is choppy. Where is the mistake?
It is necessary to solve this problem Nokia as soon as possible.

Hi,

Does any ffmpeg or mencoder expert know correct parameters to encode this kind of video? I guess 2 Mbps would be enough.

I have been using settings proposed by rasteroid here, but I am not quite happy with the video quality. There are too much all kinds of artefacts visible on encoded videos.

Thanks

That page atleast had wrong resolution 864 vs 854, I just fixed the wiki to 854, if you have encoded with 864, then try to reencode first.

I only read the 1st seven pages, sorry. But if that's what I wanted, what would be THE BEST SETTINGS?

I know h264.mp4 @basic profile (3.1) + AAC.
What settings are advised for
- video bitrate, CBR and period max. (as in VBR)?
- are these settings the same for 854x480 and 1280x720?
- encoder (mainconcept, ffmpeg, ...)?
- is framerate kinda fixed @ 30 fps or might 25 fps improve playback as of less frames?

Talking about playback with the default player on N9 here.
What would be second and third best choice for codec?
