i have the Vero 4K+ and i have an issue with streaming higher bitrate files from my NAS (for example the 140Mb Jellyfish, which stutters like crazy if played from the NAS). If played locally, the 300Mb Jellyfish plays without any issue. I have tried to see if the network speed is the issue, but according to the Iperf3 test, this should not be an issue:
the HEVC 10-bit has the same issue, but i still think it has something to do with the network as all files play fine from the Vero itself, also the 140 Mb 264 file.
The SMB source may be too slow; or there may be some overhead from Kodi’s built in SMB mounts. I notice you are also scraping your library as well; which may be causing network overhead or even CPU overhead if you have a large library. If your library is up to date already; then the additional scanning may be because of nofasthash in your customised advancedsettings.xml.
I did some teste with jellyfish videos on Vero4k in the past.
From 500GB HDD connected through USB 2.0, it plays jellyfish until about 180Mbit/s bitrate.
Over 200Mbits, its USB 2.0 wont manage to play it smoothly. But from internal 16GB storage, even 250Mbit/s bitrate ones plays fluently. This may give you some insight about what bitrate can Vero4k handle. Even in case that no one even uses such high bitrates in real life.
HEVC can play 300Mbps easily; but the H264 decoder is less optimised. As there is no real world H264 content hitting this bitrate, we didn’t look in to this much. Everything H264 that is real world content (that isn’t hi10) will play fine.
The 300Mb file plays fine from internal storage (as i mentioned in the OP), but stutters a lot when played from my NAS (DS218+), just wondering why that is, as everything should work fine and the network speed should not be the issue, but you are right, i have not found any real world content that the vero 4K+ cannot handle over the network (i did find a few files that the Vero 4k could not play over the network)
This file played fine on my 4K+ served via SMB from a Windows 10 PC (also while the Windows PC was streaming content from elsewhere at the same time) so it looks like you were right about a network issue
you mentioned this before:
nofasthash in your customised advancedsettings.xml.
It’s a while since i setup my Vero (copied the config of the 4K to the 4K+), but i think i never set up the advanced_settings.xml file, at least i cannot find it in the userdata folder… Is that what you meant?
I tried it from an NFS share(my NAS is the only wired storage i have), and the performance is much better! the 140 Mb files play flawlessly, the 250 and 300 Mb files also play fine after short buffering. Should i increase the buffer size in advancedsettings for better performance? i think it buffers about 10 seconds max right now.
I access to my NAS with NFS protocol
