It seems like my Rpi4 can't handle Mpeg2 streams from my Mythtv backend. Video is choppy and the audio is way out of sync with everything except for animated shows like Family Guy, they play fine??? My model 3b with hardware decode plays everything great.
It doesn't look like a CPU thing as the on screen debug output only shows about 50% CPU utilization. I transcoded a few recording to h264 and they play fine and I could live with that but live TV is unwatchable.
Anybody else experiencing this or have any ideas. I was so disappointed after finally getting the model 4 and finding out there's no hardware decode for Mpeg2.
