Hello!
I have a new RPI4 (4GB) an have installed Libreelec 9.2.1
The RPI is connected to my TV (Samsung KU6409) with HDMI.
I have not activated/buyed any MPEG licenses.
I had issues with Fast Forward.
If i had the option "sync playback to Display" on, Fast Forward (up to 32x) work very well. The Screen is updating very fast.
If i turn off this option, Fast Forward will not work correctly. For a short time it will work, but then the Video is Playing (a second or so) with normal Speed and than it Skips many Seconds. Than the Video is playing at normal speed...and so on.
If I understand it correctly, it is actually recommended to have this setting switched off. Audio bypass will not work with this Option...and my Receiver (Marantz NR1506) only use Stereo (even if the number of channels is set correctly). I don't know if this is another Bug.
I have made 2 logs:
Sync playback to Display - on
Sync playback to Display - off
I don't know if it's a bug from Raspberry, Libreelec or Kodi. I hope I'm right here.
I have also tested with an older 1.Gen Fire TV Stick. There is no issue with that.
Many thanks!
