I'm thinking more the Rock64 issues are hardware related since the stuttering can't be reproduced on other devices.

I have been able to successfully play videos (with no stuttering) from a hdd directly connected to the Rock64. But if I attempted to do multiple large skips then the stuttering would start.

Also Pine seems to have abandoned the device and making empty promises to users.

This is very interesting and disappointing to read as when I bought my Rock64 (and even now) the website clearly indicates that it is a LTS product and Pine64 commit to producing it beyond 2022.

But I hope I'm wrong and with the Linux v5 kernel that LibreELEC developers are working on, it would improve things.

I sincerely hope this too!

I am also having issues with stuttering on my Rock64 playing videos from my NAS over SMB. I'm not being terribly helpful, but I don't think it's your specific Rock64 as I am also experiencing something similar

I'm having issues playing videos on my Rock64 using Samba. The videos are mp4, have AAC audio and are 720p. The symptoms are stuttering when playing the video. Audio is fine, but the video is not smooth at all. I'm pretty familiar with symptoms of buffering issues (video and audio getting stuck and then resolving once buffering has completed) and I'm pretty sure this is not the same issue.

I have a Raspberry Pi2B (running OSMC) connected to the same Samba share and the same videos play fine with no stuttering.

I have changed the scaling_governor to "ondemand" and it doesn't appear to have made a difference.

Has anybody experienced this and/or know how to resolve it? Apologies if this is a known issue.The image I am running is the nightly-20190309-e738c7b (RK3328)

Thanks

Further to what I reported above. I have noticed that when I initially play my first video from the SMB share, it plays fine with no stuttering. If I stop that video and then select another one from the SMB share, then there is immediate stuttering.

I recorded debug logs for the first and second video attempting to capture the issue and for the second video there are errors in the log, but they don't mean much to me.

If I leave it for a little while and then come back to my Rock64 and attempt to play a video again from the SMB share then it works for the first initial video again and then stuttering again for the second. Any thoughts?

Thanks in advance

See my devices signature.

TX 7 S905X 2gb/32gb (WiFi AP6255) 8.2.3.1 (2018-01-22) Sd Card Boot (PS3 Play TV DVB-T dual modulator Tuner)

Thanks . And that tuner works well with your Rock64?

Also I'm having issues with TvHeadend on my Rock64. I have a couple of different usb DVB tv tuners:

1. Elgatato eyetv DVB-T tuner
2. OSMC DVB-T/T2 tuner (Which I believe is an Astrometa DVB-T2)

The first is recognised and shows up in TvHeadend as DiBcom 7000PC, but I encountered issues when going through the setup process. It loads 6 muxers as expected, but when scanning for channels only one muxer works, and as a result I only get 10 channels as opposed to the expected 50 odd.

The second is recognised, but doesn't load as expected. I'm currently using it with a Raspberry Pi2 (but want to replace this with the Rock64). It should load both Realtek RTL2832 DVB-T and a Sony CXD2837ER DVB-T2, but only loads the Realtek. I am using the LE DVB module, should I be using the main linux one? This CoreELEC thread seemed to think it would make a difference.

But even the Realtek tuner wouldn't scan properly. I am using quad shielded TV cable and a signal amplifier. The setup tunes properly with the OSMC USB tuner connected to my Raspberry Pi2 so I know that it's not a signal issue. What can I do to resolve this?

kostaman I'm pretty sure you've got TvHeadend working on your setup, what DVB tuner do you have?

Any thoughts on my post above?

I came across this thread in the forum, it seems to me to be related....

Thanks for your advice and for sharing your experience. Much appreciated!

I have got the latest nightly build for rock64 and have just tried to get tvheadend working.

I don't believe that LE has recognised my DVB USB tuner

Sony CXD2837ER DVB-T/T2/C demodulator

I'm not too sure what other information is required, but is it possible to get support for this tuner added?

Thanks for responding buzzmarshall. I think that i'll just peel both protectors off and stick it on. As both sides have the protector and are therefore "sticky" does that mean that once I install the thermal pad I won't be able to remove the lid on the case? The heat sink is attached to the lid, so once I install it, the thermal pad will be attached to both the lid and the cpu...

I've put some photos of both sides of the thermal pad and the lid of the case with the integrated heat sink

I have just received my Rock64 SBC. I ordered a Premium Aluminium Casing and am just wondering if anyone has had any experience installing the thermal pad onto the Heat Sink that comes with the case?

It seems to have tape on both sides of the thermal pad; one is blue tape, the other is clear. How do I install this? Which side gets stuck onto the heat sink? Unfortunately the case didn't come with any setup instructions. I have created a ticket with Pine64, but have not hear back.

Thanks

Thanks Kwiboo, I appreciate you getting back to me. I'll use the eMMC card

My rock64 SBC arrived today. Does anybody have any suggestions, opinions or comments regarding my query above?

Thanks

Hi All,

I purchased a rock64 a little while back and I believe it's going to arrive this week .

I purchased an eMMC module and usb adapter from Pine64 as well with the SBC and was planning to use that. However, since then I have read that there are eMMC modules and THEN there are eMMC modules. It seems as though there is a price and quality range with eMMC modules as there are with microSD cards.

Does anybody know what the quality of the Pine64 eMMC modules are like and whether it would be better to go with a class A1/A2 microSD card?

Thanks

Simply copy the latest Nightly .tar file into the .update folder of your SBC (via smb)

Then reboot . Update will proceed and install.

Ahh that's much easier than I thought it would be and much better than constantly formatting your SD/eMMC card to put a new image on

Things have now turned around and the Rock64 is a great SBC using LE Nightlies.

Very well priced for a quality product. Money well spent.

Thanks kostaman, that's fantastic to hear ! Yes I did purchase the Rock64 and thanks for the reassurance. Hopeful that I will see a large improvement over my Raspberry Pi 2B. Can't wait for my Rock64 to arrive!

Quote from kostaman

at the start it was a real challenge as a user / tester putting up with all the bugs during development

I can only imagine! Great effort from you guys and the developers for sticking with it and being willing to use, test and provide feedback.

Thanks Kwiboo for replying. Sorry I didn't realise the state and stableness of the Rockchip Alpha.

That's really quite exciting and thanks for your efforts and work regarding this.

As my TV restricts me to 1080p anyway, it sounds as though the current condition will work quite well.

I am not used to working with nightlies and test images. If I install the latest image, how do I update to later versions and then finally a stable release after that? Do I need to format the SD/eMMC card and start afresh by burning a new image each time?

Not sure if this is the right place to ask this.

I currently have a Raspberry Pi 2B running OSMC (Kodi) and have wanted something more powerful for some time. I wanted it to be affordable and available for purchase and delivery in Australia. I stumbled on the Rockchip downloads page for LE and saw that there was an image for Rock64 and I assumed that meant that LE was either supporting or going to support that SBC. That got me really excited as I was able to purchase one of those at a reasonable price and it is now en route to me.

I have now been reading through LE forums including this one (wishing that I'd done that before ) discovering all the issues with developing a stable image for this device and its SOC (RK3328), and I feel that I somewhat understand (it may go over my head ) the problems with the Rockchip 4.4 kernel and how things are reliant on the development of the Lima project.

So have I jumped the gun and wasted my money? What is the likelihood of this SBC getting a stable release in the future? And I understand that that could be some months away. I apologise if this has been asked already, if it has I haven't been able to find it.
