I have some « buffering » while I watch movies in 4K.
All my movies are on my Qnap TVS-873e 4G, and I watch them with Infuse Pro on my Apple TV 4K. My ethernet network works with category 6 cables.
I have the same buffering problems with Qfile or Qvideo, only with some 4K movies (not all). HD movies plays well.
I also have buffering issues when I try to read 4K videos filmed with an iPhone XS Max. Even if these videos don’t last long (between 3 and 12 minutes only), it’s also buffering or the 4K video doesn’t even start.
I never have buffering problems when I read 1080p movies.
Infuse set up are : SMB Auto (I tried with Legacy, SMB 1, 2 or 3 and it’s even worse).
My Speed Test is 103,3 MB/s (write) and 109,9 MB/s (read). It seems like it’s not enough to play 4K movies in 2160p60.
What parameters do I have to change to read 4K files without any buffering ?
If you’re seeing the same issue in the QNAP apps, then it may be very possible that this particular device is not quite fast enough to stream these particular 4K videos. It could also be something as simple as a faulty ethernet cable which is downgrading your speed.
As a test, one thing you can try is connecting Infuse via SMB to a Mac or PC and try to stream the videos from there to see if you have better luck.
With regard to 4K videos shot on iOS, these have a few unique characteristics and the upcoming Infuse 6 release will add much better support for these (especially those with high fps).
The Qnap TVS-873e seems to be fast enough : quad-core AMD serie R RX-421BD 2,1 GHz (Turbo core > 3,4 GHz) + GPU Radeon™ R7 (for 4K reading).
My ethernet cable is equiped with category 6a cables.
I will try to stream from my MacMini as a test, thanks.
Iperf3 is available for the Mac. It’s what I use at home (it’s not in the App Store as it’s a command line app). You’ll also need to install it on your NAS if it isn’t also pre installed. You should be able to install plex media server directly on your NAS.
Cat6 cables aren’t really going to give you an advantage for a simple home based network. All it does is eliminate crosstalk and other interference. You’ll really only see the advantage of running a giant bundle of cables through ceilings or if running 10Gig (which I wouldn’t recommend over cat6)
OK, thanks, I will try to do that.
Yesterday I have tried to put Infuse in FTP mode and it seems my movies in 4K are ok. But I just watched 10 minutes so I need to test it with a 4K movie of 2 hours. I also need to test it with iPhone XS Max movies in 4K which I couldn’t read at all (I don’t know why, because these films lasted less than 10 minutes… Very strange).
My ethernet home network is built with category 6a cables : is it ok ? I want to expand my network in my bedrooms : should I install category 7 cables or 6a are enough for the 10 years to come ?
To address the Ethernet question, cat 6 is sufficient. I’m currently running cat 5e throughout the house (pre wired in construction) without a hitch.
I wasn’t trying to be funny when I said that even a cat 6 cable can go bad. They don’t always fail by completely not working, they can fail and still pass data, just very slowly. Temporarily replacing each of the suspect cables is a cheap and easy trouble shooting step.
I will test my cables. I’m thinking about replacing cables from Apple TV 4K to my network and cable from my NAS to my switch Netgear GS 108 by category 7.
Currently, I’m using category 5e cables. And cables which are in my ceilings and wall are category 6a.
