Finally we got some patches from RK for the micro-stutter and HDMI Audio problem,but we want more videos to verify

[digger]

I use OHC kernel and resource from 4PDA.ru and get the best playback but not perfect.

What do i have to do to adjust to DDR792/1,35V on KK as I'd like to try it?

What are your current dvfs settings?
It'll be much easier for me if you upload your resource.img file and I'll patch it for you.
It's not my secret, I prefer to use a tool which was created by Jabader from 4PDA and you can find it here

O.K.
My settings for CPU and GPU are the same as yours, and your top DDR frequency is 800 too, but your voltage corresponds to 0x12b128(1,225V). I have 0x149970(1,35V) at the same point.
Try to replace your DDR part of dts file to
clk_ddr {
operating-points = <0x493e0 0x100590 0x60ae0 0x10c8e0 0x78d98 0x118c30 0x80e80 0x118c30 0x91050 0x118c30 0x99138 0x124f80 0x9e340 0x124f80 0xa4100 0x124f80 0xc3500 0x149970>;

auto-freq-table = <0x493e0 0x60ae0 0x78d98 0x80e80 0x91050 0x99138 0x9e340 0xa4100 0xc3500>;
auto-freq = <0x0>;
};
};

Thank you...

Do you know where is the problem?

[Gormar]

What do i have to do to adjust to DDR792/1,35V on KK as I'd like to try it?

You can use my overclockmatic_RK3288 tool.

IMO Setting 1.35V is a little risky. One shouldn't go higher for DDR voltage than 1.3V.
Beside I realy do not see any difference between 700MHz and 800MHz DDR RAM settings but default 456MHz is rather too low.
You can see more improvement from unlocking real 1.8GHz frequency for CPU in kernel than 800MHz for DDR RAM in comparision to 700MHz.

You can see bigger performance improvement from unlocking real 1.8GHz frequency for CPU in kernel than 800MHz for DDR RAM in comparison to 700MHz.
It is quite a ruse to sell devices advertised as 1.8GHz SoC and then limit CPU speed to 1.6GHz but still display in kernel CPU governor settings 1.8GHz as available .

That post is now gone, freaktab moderators please investigate.

I tested http://jell.yfish.us/ 80mbps video and got 12-15fps but no dropped frames or high CPU usage in SPMC.
Is that normal or should file's frames per second be 23.97/24/25 or 30.
If so, then it is another problem with high bitrate videos on RK3288 devices.

Is 1.8Ghz CPU and 600Mhz for DDR & GPU dangerous for normal medium stock heatsink on HPH devices or no need for extra cooling?

[AndreyZ1980]

We must first finish 23.97fps 5-15Mbit, (mostly as common format) And then 4k, 100Mbit

[RISCy Dude]

I'd be curious to know what the temp on the HPH is after a benchmark run, or during HD vids. Even like to know for stock speeds. Got any data?

Here gather my thoughts together:

1. Where is the video clips playing from? NAS/USB Drives/Internet Streaming/Local eMMC?

2. What VideoPlayer used? Kodi/RKvideoPlayer/SPMC/MXplayer?

3. What's the HDMI output mode? 1080P24 or 1080P60?

4. What's kind of videos? 23.976fps MKV H264?It's better to use 'mediainfo.exe(https://mediaarea.net/en/MediaInfo )' to check.

5.What's the frequency the stutters occur ? on time per 1min? or start to stutter after 1 hour playing(Because of thermal hot)?

[AndreyZ1980]

1. Where is the video clips playing from? NAS/USB Drives/Internet Streaming/Local eMMC?

local network, nas, internet streaming

2. What VideoPlayer used? Kodi/RKvideoPlayer/SPMC/MXplayer?

SPMC, MXplayer

3. What's the HDMI output mode? 1080P24 or 1080P60?

1080P60, in other mode very big stutter

4. What's kind of videos? 23.976fps MKV H264?It's better to use 'mediainfo.exe(https://mediaarea.net/en/MediaInfo )' to check.

23.976fps MKV H264

5.What's the frequency the stutters occur ? on time per 1min? or start to stutter after 1 hour playing(Because of thermal hot)?

on time per 1min

Would be handy if we all try the same file/file type as I get the impression its a hardware issue which some of us suffer more so than others which is why some say things are fine.

[bluesmanuk]

Thanks digger and gormar for the tips and tools

[bluesmanuk]

Would be handy if we all try the same file/file type as I get the impression its a hardware issue which some of us suffer more so than others which is why some say things are fine.

I'm wondering whether an online spreadsheet may be a good idea, where a list of files and respective download locations can be listed, with each user putting their results in of all the files that we ourselves test.

This could then be used further on down the line to test for other ROM revisions and new boxes.

Perhaps something along the lines of this?

https://www.dropbox.com/s/wtqkv12cgm3sevu/Video%20Testing.xlsx?dl=0

It could be put online for global editing.

Firstly everybody comes up with a list of files so that one list can be compiled and then, when we are happy that the list is complete enough to gain meaningful results, each user can than have their own spreadsheet tab to fill in, giving their own individual results and feedback.

Sounds good but maybe a spreadsheet per sample file as there are so many of them. I doubt most people will download more than a few of the test files. If we can make sure we ask all the relevant questions to cover all the bases, dropped frames, rom base etc.
