NextPvr timeshifting problems on 720p video

    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?

    Thanks

    For problem #1 I've already told you the timeshift logic has changed https://forums.nextpvr.com/showthread.php…56141#pid556141 I am not sure why you don't get it and keep asking this question. Did you follow my suggestion here https://forums.nextpvr.com/showthread.php…56458#pid556458 to reduce the timeshift buffer size? You never responded.

    The other problem clearly requires your Kodi debug logs. However this seems to be a duplicate post of this problem https://forums.nextpvr.com/showthread.php…58166#pid558166 and it is not clear why you don't pursue it there because that problem was a backend problem.

    Martin,

    I'm questioning your reading comprehension. This is not the same problem because the timeshift problem I reported only happens on the RPi4 platform and only with 720p video. I specifically stated that 1080i timeshifting is working correctly. I also told you on the nextPVR forum that I tested timeshifting on my Windows 10 laptop and everything worked properly so this is a platform issue specific to the RPi4.

    As far as the player stopping randomly, I see I'm not the only one complaining about that problem. In fact others have reported that the problem still exists in the current V5 backend version and in my opinion, the problem has gotten worse compared to the previous release.

    I do not appreciate the arrogance you display when responding to my requests for help and as we use to say in the military, you definitely need an attitude adjustment!

    I referred you back to NextPVR because you have a habit of leaving these threads dangling. If two threads deal with problems at 47 minutes they are linked no matter what you feel and as I posted on the Kodi forum I do not relate this problem to 720p. It certainly might be the addon or possibly LE the but this takes logs to investigate which you don't include.,

    Sorry if I take defensive to your continued references to Krypton but were are working on Nexus now. Both the server and Kodi API's have changed completely, and there is no going back. My involvment

    Thanks for the kind words and I have adjusted my attitude by changing my user block lists.
