TvHeadend setup help

My current setup:

Back-end :

Rpi 4 with Latest version of Tvheadend on Libreelec, using Pi's Tv head

Front-end

Nvidia Shield using PVR Live application to pull in TV channels into Live Channels app.

My issue

Changing channels on Nvidia Shield is slow (between 10 - 20 second delay) when using a matroska stream profile. Using pass only works for a few channels HD channells but appears to be slow as well.

Tried Kodi on Nvidia shield and it uses htsp profile and yet again changing channels is slow.

I have tested my network using iperf and i do get a full gigabit connection between fronted and backed. U suspect it could be something to do with the streaming profiles and their setup, but that were my knowledge ends unfortunately.

I am based in UK if that helps.

Any help if highly appreciated.

then you already partly transcode the stream, that is not what you want

this is the way to go, what means slow, 2sec? 10sec ?

can you do a screenshot of your settings ?

Btw pls also try Kodi at Windows if there are the same problems. The Shield should do it but you never know.

Normal switch speeds are around 2-3sec. Worst case is <5sec for a full channel switch.

Just tried Kodi on windows and exactly the same channel switch time , over 10 secconds using HTPS

go to Configuration~Users~Access entries and click on the account you r using...in this case administrator then click edit...and check that the streaming profiles you r using are all enabled for that user..I have a feeling htsp is not enabled properly and your setup is defaulting to some transcoding profile..

Menu looks like in this image:

Just checked and all profiles appear to be enabled.

Using Kodi on Nvidia Shield with a HTSP steaming profile appears to be working and channel switch time is down to like 3 seconds, which is great and thanks for your help.

However using Live Channels with pass as stream profile is still fails. I can see a subscription to a channel in TVH with Input and Output figures changing constantly but the tv screen still displays a loading circle. Feels like a codec issue somewhere, anything else i could try?
