Re: Multi-Seat use of RPi 4

Multi-seat works in principle, with the exception of audio. Currently that is only supported on one of the micro HDMI ports, not on both. Seems like a nothing-burger. I don't think HDMI ARC works anyhow, so you are limited to one microphone input. This means the second user would already need somet...

Re: Raspberry Pi 4 Thread - general discussion

If I understand correctly the Pi 4 changes the GPU to 600 Mhz when operating in 4K. Why not always operate at 600Mhz? If 600Mhz is a normal clock operating mode, then what have some of you been able to clock the GPU beyond 600? Tom's Hardware tested at 600 with good results, but again that doesn't s...

Re: Raspberry Pi 4 Thread - general discussion

What part of desktop performance? Of course, the CPU's are going to be busier, so there are less CPU cycles to run 'the desktop', but on the whole, a desktop is mostly idle anyway. Let me clarify :) I own three boards and have use cases that don't involve using them as a desktop replacement. Althou...

Re: Raspberry Pi 4 Thread - general discussion

I've tested raw BluRay MPEG-2 and VC1 with LibreELEC on Pi4 and both played fine with software decode. Broadcast TV tends to be a much lower bitrate so there shouldn't be a problem. What kind of CPU utilization did you observe? Did this effect desktop performance? What part of desktop performance? ...

Re: Raspberry Pi 4 Thread - general discussion

Some DVB-T TV channels use MP2 (e.g. in Sweden) and this could mean that playback is worse on Pi 4 B than on Pi 3 B+. I have not bought a license key for MP2 so I'm not using the hardware decoder anyway. I use e.g. VLC to watch TV using TVHAT on Pi 3 B. Denmark, which is close to where I live, uses...

Anybody tested fullscreen youtube playback? If this works smooth, even with 720p, this is a board worth upgrading for casual web browsing.
Initial reviews say video playback on the desktop with YouTube is poor unless the window and resolution is reduced.

Re: Raspberry Pi 4 Thread - general discussion

What an amazing engineering achievement! Great to see the usual well thought out evolution of the RPi. I'm glad the Videocore is still part of this SOC too. I assume full backwards software compatibility for Videocore/dispmanx support? Is 3D MVC support still in the chip? Was concerned about it sti...
