I'm running LibreELEC 10.0.0 on my Raspberry Pi4s. I have 2 particular problems running Kodi Matrix that I don't have when running Kodi on my Windows 10 laptop.
The first problem is how long it takes to change to a different channel. Compared to Kodi Krypton, it takes twice as long to change to a different channel. Under Krypton it took less than 5 seconds. Now Under Matrix, it takes a minimum of 10 seconds.
The second problem I'm experiencing Under Matrix is timeshifting problems when viewing 720p video. It doesn't matter if we're talking about live TV or a recording, the computation of the shift amount winds up going all the way back to the beginning of the program and stalling.
For example, this morning I was watching GMA (720p) which was at the time, 15 minutes behind real time (FYI, I deliberately watch time delayed live TV so I can skip commercials). At the 47 minute mark, I tried to go back 1 minute and nothing happened. Clicking select on my remote I could see that the time indicator had moved back to the start of the program. Although the time indicator was moving forward, no video was playing.
Another example was a recording of the Wonder Years, a 30 minute show in 720p. As I was skipping over commercials I got to the 20 minute mark when the next timeshift of 3 minutes resulted in no action. Clicking select on my remote showed the time indicator had gone back to the beginning of the show. And just like my previous example, I could see the time indicator moving forward but the screen frozen at the last displayed image.
I'd like to note that timeshifting 1080i video does not exhibit these problems - only 720p video. I'd also like to note that I don't have these timeshifting problems on my Windows 10 laptop.
Has anyone else experienced these issues? Is there anything I can do to fix these problems?
