i give up... spent 2-3 days on getting my new rpi4 (2gb, with 256mb GPU ram assignment) to playback HD content smoothly and just can't. playback profile is setup to use V4L2 codecs, and I've upped core count to 4. Tried none, software, oGL and driver deinterlacers and disabled deblocking to try and improve things but non of them really fix the issue, just make it worse depending on system load.
rpi4 not overheating (around 72c during playback and running the full 1.5ghz)
seems like i could be dealing with multiple issues too.
first, any playback of HD content feels like it's dropping frames. also seems to jump every few seconds. almost like a rpi3 does with HD content with 'ondemand' governor.
second is HD deinterlacer. LiveTV seems to correctly detect HD content as interlaced (correct; UK is 1080i broadcast). Recorded program gets detected as progressive. I'm having to change this manually every playback to interlaced.
Third, very intermittent screen blanking where hdmi video&audio both cut out but resume again after 2-3 seconds. doesnt seem to be related to anything specific and seems completely random. I'll be placing an order later for a new HDMI cable to see if that helps but not sure this would have an effect on the above..
thanks for any help on this - its driving me insane !!
