Hello !

I try to find a way to set hdmi hotplug on my rock64 AND to force a specific resolution to the rock64 also.

I want to install my rock64 in my camping car, when I plug the power on my camping car, tv power on and the rock64 power on also but it finish to boot before the television. Each time I have to turn off the rock64 and restart it. What I want is that the rock64 boot at a specific resolution even if the HDMI is not plugged.

On a Raspberry pi it's easy to do, there is a way to do that on a rock64 ?

Thank you !

I am connected to a 4k avr and the avr is connected to a 4k télévisions.

Just to be sure, I reinstall from scratch my Lite 2 with beta 2 (9.95.2) image and I confirm that the image works well.

You probably know but I talk about this image : LibreELEC-H6.arm-9.95.2-orangepi-lite2.img.gz

minnix I have an Orange pi lite 2 and the beta 2 image works well.

I always use Auto refresh rate switching = on. I agree with offbeat it's a must.

jernej can you remind me the "echo" command to set to performance ?

I try this :

echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

But it doesn't work

-sh: can't create /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: nonexistent directory

offbeat , thank you for the trick "set algorithmdirtyregions to 0" it works well.

Hi jernej !

I played with my Orange pc2 and I can confirm that my PC2 work as well as my Orange pi PC.

I found a way to help my Orange pi PC2 and my Orange pi PC to stop freezing because of low memory, I enable the swap file, I set the swap file to 512MB and that help. No more freeze at all, some slowing down when the device access the swap file but overall that help a lot.

It's sad that we can't enable Zswap, it's a lot better dans the swapfile. I use Zswap that on other devices at home and that work really great. For device with 1 GB memory Zswap can do a huge difference.

Zswap is a battle that I can't win, other people tried before witout success. Anyway, in my case I play with these devices only for fun of testing.

I have a problem with my Orange pi 3 and Pine H64. All my 1080P contents (movies and episodes) are jerky (not smooth). The only workaround I found is to put devices to 2160p and whitelist only 2160p resolution. That way all my contents play well.

Do you have this problem on your side ? This problem doesn't exist on my raspberry pi 4, orange pi PC and Orange pi PC2.

Hi !

I did tests with my Oprange pi PC, I have a AVR Denon AVR-S730 and passthrough work not too bad at all

Dolby Digital : OK

Dolby Digital Plus : OK

DTS : OK

DTS-Hd : OK but a lot of clipping (cracking/popping, I don't know the good word in english, this append also with H6)

TRUE-HD : not tested

A really weird bug : If a disable AC3 transcoding, I set the number of channel to 7.1 and I watch an episode or a movie in AAC 5.1, I hear only the background music, no dialog... But if I set number of channel to 2.0 and I enable AC3 transcoding everything is fine.

Another thing, with the "not passthrough release" I have a lot of sound cut, it's totally random it's really disturbating but with the passthrough relesase I have no sound cut.

So personnally, passthrough edition is my favorite release, I disable DTS-HD and TRUE-HD passthrough, I enable AC3 transcoding and everything work pretty well.

jernej Just for your information : I received my Orange pi 3 today, I installed last nightly image on it (LibreELEC-H6.arm-10.0-nightly-20210427-59c8aa4-orangepi-3.img), but it seems that this image is little buggy. I am unable to play movies with it, I got a black screen on all movie I try to play.

I falled back on beta 2 image, that one work correclty.

jernej No problem for me ! Thank you !

jernej Is it possible to have a new release of your "librelec passthrough edition" with all modifications you did since febuary ?

levitsky86

Did you try that ? I don't know if that work for IPTV....

HOW-TO:Modify the video cache - Official Kodi Wiki

kxe2 You can try with the official image : LibreELEC-H6.arm-9.95.1-orangepi-lite2.img.gz

I use this image on my lite2 successfully. Normally, nightly image should work also but I don't use it now.

jernej With my Orange pi PC, I got an out of memory during browsing my Recently added movies : http://ix.io/2TkX

jernej I confirm that wifi doesn't work on Pine H64... For Bluetooth I don't know.

jernej I tried my orange pi PC (not the PC plus) and first problem : No Network. I going to do a test with my Orange pi PC plus to check if I have the same problem. My Ethernet cable work well with my Orange pi Lite2 and my Pine H64. Forget that !

Hi knaerzche

Do you know if the bug explain in the link below is a bug that can be correted ? Personnaly I think that Rockchip devices run very well but that bug is really disturbing for 4k movie.

That bug exist with my Rock64 AND my Rockpro64

4k Quality on Rock64

I know that rockchip release of Librelec is only a beta, I'm just curious to know if that bug should be fixed in a future release.

Thank you !
