On my Raspberry Pi Raspian installation I am not able to get the 7th video to load. Nimble Streamer does not serve the 7th connection, 1 to 6 work fine although some have lag.
Please see this image for reference, 7, 8 & 9 connections keep waiting:
Please try connecting you Raspberry to LAN via Ethernet cable, will it fix the issue? What is the size and duration of the file you're streaming?
Do you stream vod or live content ? if vod please make sure your ROM subsystem have enough speed
I am using it for vod. Any specific ROM subsystem settings that I should be making ?
vod transmuxing requires quick ROM subsystem. if you cannot load more from your server - PI is not vod option you need.
We cannot help there
