Hi, I recently purchased a lifetime Emby Premiere license to try Live TV with both of my HDHomeRun Prime tuners. I saw that Emby advertised fast channel changing with a decent guide and the possibility of viewing TV remotely, so I thought this would be a good solution for my needs.
I'm running Emby on a Xeon E5-2698V4 with 16GB of RAM, because I wanted fast transcoding times. My client is an Nvidia Shield TV, but I also tested channel changing on the server itself and both are slow. In the beginning it was taking 45 seconds or more to change a channel on my local 1GB network, which was disappointing. I turned on Intel Quicksync and this dropped the channel changing time from 45-65 seconds down to 15-18. If I enable direct play, then it drops down to 10-15 seconds. When I use other direct play clients, like HDHomeRun or Live Channels, the time is only 1-2 seconds.
Everything else I've tested in Emby seems great, but if I can't drop the Live TV channel changing time to 1-2 seconds similar to other Android TV clients (direct, I don't expect transcoding to be this fast), then this product will not be useful for me. I also think that other potential customers should be made aware of this problem prior to purchase. If you're advertising fast channel changing, then this is what people will expect when they purchase the product.
After searching on this forum, it looks like this may be the normal performance of Emby for Live TV. If anyone knows of a way to improve channel changing times, please let me know.
