overclocked kernel is here

[BrunoNRG]

For some reason, replacing the fans by an heatsink got me a better score on the latest antutu

NEOTV CR 1.0 Neomode Custom Rom 4.2.2 - Sam's 720p 1.9ghz ram 1500mhz "old" oc kernel

[bigiuly]

I have a question: if I use 720 kernel and on settings/display/screen size is 1920x1080 this mean the image is upscaled? so is better to use 1080 kernel on FullHD display?

THX

So i was right ?

i dont know what you mean but if the kernel is 720p and the stick settings are set to 1920x1080 then everything is just upscaled, even if you play a full hd video it wont play in true full hd. If you have a 1080p kernel, then you can say that the resolution is true full hd and the playback will be true hd. Cheers

You just keep referring to upscale this upscale that.

Look this is native 1920x1080 resolution, the video is true 1080p resolution(if you play 1080p video). BUT this rom just performs best with 720p videos and not 1080p ..it's simpler than you thing

No mojo's here to "make" this seem bigger. If you play a 1080p it won't be as smooth as if you play a 720p video

Get it? ..I don't understand what troubles you, I really don't.

To make things a bit more clear. You've got a tv or monitor and you plug in the stick, when you have 1080p monitor and that's the max of your tv/monitor then you have native resolution no upscale of any type. When you play a 1080p video it's a 1080p video playback but it's not as smooth as if you put a 720p video in your 1080p tv/monitor, of course it won't upscale any resolution, the 720p video playback would be 720p playback ..that's it!

The rom is optimised for 720p playback and not for 1080p ..but that doesn't mean you can't see a 1080p video, again it won't be as buttery as 720p but it will work.

Body the kernel which states 720p is not optimized for 720p it is 720p, it outputs 720p whatever you throw at it. Which means that if you can play any kind of video resolution but not at the original resolution. Every video that is bigger or smaller than 720p will be upscaled to 720p. And if you set the settings to 1920x1080 on android setings you still dont have a real full hd resolution. It is just upscaled. Google a little bit around or search the threads around here. Cheers

So if I throw a 4k video it should play it just the same? ..I highly doubt so but I will upscale a 1080p video and putting it into the stick (I'll get results by the night(here it's 9:37am currently)).

P.S. 720p vs 1080p doesn't seem the same to my eyes, I mean the smoothness. With 720p video it rolls better but on the other hand it might be just me, l8r with this test ..according to you it should be played just fine it will downscale to 720p so no big deal.

4k video has a very high bitrate and the resolution is very high, too. It depends on the power of the cpu and gpu and the speed of the nand memory. Its like trying to run a full hd video on a pentium 3 with few mb ram. Anyway you can test a 4k video and see how it works and post the results on a new thread about video playback on the rk3188 devices

I didn't say that the source would be 4k, just upscaled re-encoded video. So based on your theory before your story can't be verified

..that was my point, happy you confirm me (if you didn't get it, I mean that downscaling a video realtime requires extra power and can't be avoided if you just play the video as it is no matter what, so I don't believe we have the power to downscale a video realtime ..make it look like it's the original source with no performance penantly)

P.S. I'm confident that the "4k video" would suck, it will go very slow.. but what the heck I'll do it(after a few hours of cs, I wanna remember old days with my pals heh cy l8r)

Does the 720p kernel have the "framerate fix" for video playback ?

Do you know if this kernel can be applied to the new stock rom of Rikomagic ? Maybe by extracting the img file and replacing the stock kernel ?

[stadros83]

Nobody knows ?

[sam321]

yes the 720p kernel has the Video fix

[stadros83]

Ok, but question about that fix :

Is there a way to apply it directly on the new kernel from the Stock Rom ? By adding some code ?

[sam321]

yes look here http://www.freaktab.com/showthread.p...-rk3188-kernel!

Need Help - MK802IV CPU Frequency Problem

Hello Sam

I buy new Mk802iv 8G SN 21308**** last weekend, and have a problem with cpu frequency:
Antutu details show cpu frequency max at 1416 MHZ for my original stick , but is not the frequency 1608 MHZ that shown on product specification and on print screen of antutu of the product in the official web page.
I use always the power supply that came with the product.

I upgrade the FW to the last official ROM but still remain de the same frequency (1416MHZ max)
Then Install your Kernel moderate OC "1080p 1.7ghz ram 1000mhz", on this ROM but still at 1416Mhz Max.

Is a hardware problem with my new stick? What I can do?

Please help me with the problem.

Best Regards

[sam321]

For my kernels to work you must have a rom that does not have the kernel in the boot partition
