I habe some Problems regarding my Vero4k. Almost every movie stops from time to time. I need to press pause and play to continue. This is Full HD and up, DVD rips or other streaming services like Netflix, Amazon or Sky are playing fine.
The rips are direct m2ts rips (makemkv) of my blue ray disks. The files are served by my file server using nfs and a mysql database. No Wi-Fi, just Gigabit Ethernet.
Saturday I exchanged the Vero4k with my Vero4k+, just for testing purposes. (I put the 4k+ at the exact spot with the same cables.)
The 4k+ was playing The same file without any problem, perfectly fine.
I bought the 4k about a year ago, just before the 4k+ was announced. So it was about the latest batch of 4k.
Since the files do not exceed 100mbit/s, I have no idea what is causing this. Can anybody give me a hint, what is causing this?
I can only speculate but it looks like your rips might have been pushing the network and NFS limits. If you were using Kodi-based NFS mounts, you’d have improved the performance by moving to kernel-based NFS mounts (fstab or autofs).
I know. Is that a problem? I am trying to understand the problem. Even the answer, “This is absolutely normal, you need to go to Kernel-NFS.” or “Something is really wrong there, should work perfectly.” would be a hint.
Could you please explain this? I can understand Kodi-NFS is slower because Kodi has no direct access to the hardware like Kernel-NFS. This limits the bandwith if the CPU is the limiting factor.
But since the CPU of the 4k is similar to the CPU of the 4k+, the nominal bandwith of the network port seems to be the limiting factor. That’s exactly what i do not understand. Even more, because FHD movies are 20-30mbit/s at maximum.
As you correctly observe, the faster network interface raises the bandwidth ceiling.
As @bmillham has already said, without logs, we have little to go on. The quoted movie speeds are new information that you have not provided before. Slowly revealing new information to us in a drip-drip fashion is not the best approach.
Networking was the factor. I somehow “solved” the problem by adding an usb3-Gigabit Nework adapter. This doubled the network bandwidth to about 200Mbit/sec according to iperf3 and that seems to be enough for playing problematic FHD-m2ts files.
