I think 3gp would be possible. I'm not familiar witht the format but the old arm7 40mhz power razrs could run it and we know the DS has more power than that.

 

[spinal_cord]

I always thought phones used dedicated hardware for video rendering...

 

[Sarvesh50]

arm7

and arm 9 youtube ?
hmmm posibile jes no?
jes
Difficult?
HARDEST.

 

[cas2007]

i think most mobile phones run on a faster processor than the ds now a days

 

[spinal_cord]

I'll try again...

1. Downloading anything of any reasonable size (like a video) takes forever on a DS.

2. ALL videos would need to be converted to a DS friendly format BEFORE downloading to the DS, the DS is not fast enough to convert a video in any reasonable time. Remember home PC's in the early 90's? no? well full motion video was barely possible and at best, really poor, never mind converting a video clip in less than a couple of hours.

I understand point one, but what we are saying is can't we use the 3GP can't someone make a reader for it like DPG etc.

 

[scrawl]

Essentially an FLV file comprises an MP3 audio stream and a video stream encoded with On2's VP6 codec.

VP6 is optimized for low data rates and low power requirements for decoding - pretty much originally designed for mobile apps and devices.

This is why On2 also has embedded software VP6 decoders for various processor cores, including the ARM 9 and the ARM 7.

From a hardware standpoint, I believe the DS has enough CPU speed and RAM to decode VP6 video in realtime (as to what degree, that I can't say). I suspect the rea barrier would be software optimisation. Hombrew is based on reverse-engineered knowledge by some very talented people - In it's current state, it would be difficult to really optimise the software for the hardware. What could be interesting is reprogramming the Flashcart's CPU (most contain a ProASIC 3) and run everything in hardware, though I don't think the homebrew scene (or even the electronics design industry in general) is quite at this level of sophistication yet.

One final curve ball is more modern FLV's can contain AAC audio and H.264 video components. These do require greater processing power to decode which might be beyond the ARM 9 processor.

 

[Mohammad]

*sigh* scrawl, not the FLV but the mobile 3GP on mobile youtube, then yeah maybe someday we will have FLV support, but just to get it up and working can't we use the 3GP?

 

[OrcMonkey©]

maybe you can make a flv player

 

[Mohammad]

right but a 3GP player would be quicker and a proof of concept... :/ and FLV can be done but the question is how long will it take to develop then how long will it take to download :?

 

[pasc]

nope.

Youtube videos are far too huge and complex for the ds to cope with. If you look at all the ds video players that exists, the videos need to be converted first, it just cant cope with a normal format.

then how about a flv player ?

I give up.

lol that was a joke

 

[matrix121391]

It might be possible. Don't they have a DS TV that's available only in Japan?

Remember home PC's in the early 90's? no? well full motion video was barely possible and at best, really poor, never mind converting a video clip in less than a couple of hours.

why would it be required for videos to be converted to DPG or any other ds format? it is possible to code a player which can handle other formats too. for this specific purpose, one could create a video player specifically for playing 3gp.

TV is a completely separate over-the-air technology. It's not wifi, and I'd be surprised if the DS itself handled all the processing rather than letting the TV addon handle most of it.

Because the DS doesn't have the power to play back regular, unmodified movie files. I think it was Chuckstudios that once worked on a generic MPEG player for the DS. It ran at 5 fps.

Also, "3gp" is not a single standard video type. Like AVI, it's a container format, meaning it can contain multiple types of video and audio within it. Some 3gp files may contain video that's possible for the DS to decode while other 3gp files have a different internal video codec that the DS can't handle. Wikipedia tells me that 3gp files use variants of MPEG4 for video. The only implementation of MPEG4 I've seen on the DS ran at less than full speed and without sound, and that was with pre-converted video files.

 

[psycoblaster]

I'm pretty sure its possible, as the DS isn't as weak as most people make it out to be. Its just that currently DS developers don't have the required software to utilize the full potential of the DS's hardware.

You have to remember that with hombrew everything is compiled by the community for the community. So libraries and development software, go only as far as the leading heads of the DS homebrew scene want it to.

What I'm hoping is that the HomeBrew bounty will attract more amateur and experienced developers onto the DS Homebrew scene. Such as myself, and hopefully you. =]

wrong, wrong, and errrrrm... wrong

So your basically saying the developers that work for Nintendo officially are stuck using DEVkit...Yeah GG. =]

A homebrew that let you browse on youtube and watch youtube videos.
Is it possible?
browsing on youtube might be possible but videos are... no.
well it's possible with win2ds (you can browse, and probably watch) . But it doesn't work the way you are thinking about.





Oh i just remembered!!! You can view them like a charm!!!
Go to google, type in "psycoblaster's youtube4DS"
currently it's version 0.04 so only videos 4 minutes or less.
remember - you need a fake R4 and a bricked DS, or else it doesn't work.

but when did I ever mentioned the developers working for nintendo? i didn't even use the words "developer" or "nintendo".
have you ever played a game that has lagged on your DS? well what does that mean? have you figured out now?
full potential of the DS's hardware
well yeah I might be wrong on that but if a commercial games made for the DS lags, if it did use the full potential, just think how unplayable it will be.

Just go to google and look at the specs of an NDS, and you'll see that it IS weak as people think.
DS isn't as weak as most people make it out to be
well, wikipedia says it too!
One 67 MHz[1] (ARM) and one 33 MHz ARM7TDMI
that is something that you can't change, unless some type of hardmod changes the processing unit of the DS o.O

as far as the leading heads of the DS homebrew scene want it to
hmmm
that statement would be true if you reworded it. but "want it to?"
and "leading heads???"
there is no "top creator" of homebrew; there might be somebody that's good at programming, but that does not make them a leading head.

i'll reword it for you:
So libraries and development software, go only as far as the knowledge of the "leading heads".

For all of you who are saying that videos need to be converted to dpg first, ur wrong. Don't forget homebrews such as tuna ds, tuna-vids,etc.(i think thats what it was), which allows you to watch .avi files :3. yes they were converted to 256x192 on the spot, but still, it worked :3, why not do the same for flvs. Also wifi speed on the ds isn't so very slow as you guys say it is, I can browse quite quickly through DSO and bunjaloo, and i can dl zips etc, not as fast as pc but close enough.
Ken

well you still have to convert them... don't you?
why not do the same for flv's? you still have to convert them to some type of video file, don't you?
And wifi speed on the ds isn't so very slow??? then try using DS2DS to send a file to somebody else's ds using wifi.
and you'll see how slow it is.

 

[spinal_cord]

The only way to do this, is to set up a NEW youtube, with ds-formated video on it. Even then i would really hate to wait ALL DAY to download a clip.

but unluckily that won't be a youtube

buffering!.....
plays for few seconds...

buffering!

You meana phone is even more powerful than a DS?(talking video-wise)

 

[psycoblaster]

yes.

I think even the ipod nano has a better CPU. I know it has like 32 mb of RAM.
