Re: Nokia N9 video codecs required to play 1080p
 

what dsp you get in the soc depends on what gpu is in the soc, so by nokia choosing a shitty gpu for 2011. you also get a shitty dsp
vias dsp is better as it obviously has a better architecture as it plays any 720p video withouth a problem on a much lower freq and probably with needing much less juice
and consider that vias soc is low end and cheap

Re: Nokia N9 video codecs required to play 1080p
 

Can we using extra decoders from n900? Noob question , sorry

Re: Nokia N9 video codecs required to play 1080p
 

what would you gain with that? n9 and n900 mostly play the same videos, a sad fact since n9 is 3 years newer device

alternatively, someone could port tcpmp since it is open source and i think that **** plays any video smoothly on any hardware

Re: Nokia N9 video codecs required to play 1080p
 

It's software issue , nothing to do with hardware.

Re: Nokia N9 video codecs required to play 1080p
 

in case it helps...

Re: Nokia N9 video codecs required to play 1080p
 

There's always a software part. A poorly written piece of software can bring the most powerful hardware to its knees.

Not that N9 is the most powerful hardware ;)

Re: Nokia N9 video codecs required to play 1080p
 

nokia n9 dsp cant handle 1080p and that is that, pure hardware issue
you can play it over cpu but that will be either really slow, or the player needs heavy optimisations(read:image degradations and frame dropping) like tcpmp does on symbian and windows mobile devices

i really dont know why are some people making this kind of claims when it is clear that they dont really know what they are talking about

Re: Nokia N9 video codecs required to play 1080p
 

yes, naturally there is a software part, but no software can make hardware limitations disapear

Re: Nokia N9 video codecs required to play 1080p
 

Extra decoders support make stok video player on n900 can play almost anything, flv file for ex , n9 stock video player cant handle that, cmiiw

Re: Nokia N9 video codecs required to play 1080p
 

2 years younger (and slightly less even).
But yeah... sad still

Re: Nokia N9 video codecs required to play 1080p
 

Oh god.
No.
The truth is as GrimyHR said.
Decoding of a video stream can be done:
- By hardware, ie by the GSP chip. In such case, the chip can decode smoothly anything it has been crafted for, almost independently from the CPU/GPU power. To add new formats, you need to change the chip (ie you can't). The N9's DSP can do h264 decoding up to 720p base profile, and nothing more, it is written in its specs.
- By software, ie using a codec. In such case, you are limited by CPU power. A dual core 1.5GHz Atom CPU cannot even handle 720p, so there's no way you will get the N9 CPU to do it (nor any other embeded ARM soc probably). With the good codecs, the N9 could display HD videos, but certainly not above 5 fps, which would make it completely useless.

Conclusion: no 1080p video on the N9, end of discussion.

Re: Nokia N9 video codecs required to play 1080p
 

Yeah...

my 808 could play some 1080p WMA that my PC (AMD A-6 + ATI 6750) struggled with in VLC (Media player did fine here), and some core i5 didn't have the horse power to run on any player.

Re: Nokia N9 video codecs required to play 1080p
 

A 1.3 ghz cpu , a pretty capable gpu & a dedicated camera cpu along with the optimised S/W (Symbian) do the trick.

Re: Nokia N9 video codecs required to play 1080p
 

I dont give a s**t bout 1080p, can we dream bout 720pall profile?

Re: Nokia N9 video codecs required to play 1080p
 

nitdroid plays hd vids much better then harmattan. In harmattsn they dont even start but in nitdroid it does play hd but with some stutter. So better support in harmattan seems to be possible.

I will try more in Nitdroid to see what vids work and does not.

Re: Nokia N9 video codecs required to play 1080p
 

Possibly, if you're very good at writting SoC drivers, or have enough money to convince them to port these ones. (N9 has OMAP3630 Processor with IVA 2+ video chip)

99.999% a dream though.

Re: Nokia N9 video codecs required to play 1080p
 

So it is possible, by combining CPU + DSP power. They even have a GStreamer plug-in, so it says. But I wonder what this will do with energy consumption, as not only the optimized DSP is used but CPU as well...

Re: Nokia N9 video codecs required to play 1080p
 

Yeah also realized nitdroid plays most vids. I have to play them in the mob player app though using software decoding.
