I do not know if it related but I get some of the same errors after a day or so using LE11 This is with a pi4 2gb connected by ethernet with tvheadend on a separate box serving mpeg2 streams. The video will start to have audio skips and then eventually green artifacts flashing on the screen and then if you stop playback it will not start again. If I disable de-interlace in the osd video settings menu then I do not get this crash. It also will also happen eventually if playing media from my file server it just takes longer since most does not need to be de-interlaced.
