Re: Power station for PI4

Also ... Pi4 does not need the full 3A for itself.
So if you are not planning to add power hungry USB peripherals to your Pi4 then lower power is fine.
See the specs for more detail.

Re: OTA TV in the US?

OSMC is outdated and not supported as well as libreelec. I read a comment from Sam Nazarko (OSMC) that the approach being taken for RPi4 support is different between Libreelec and OSMC. He wrote soon after RPi4 release: this (Libreelec) approach uses MMAL and some patches to make it work with GBM. ...

Is there an official way to get the base address at runtime (i.e. not using defines). With older Raspbian builds it could be found via /proc/iomem with different keywords depending whether or not device tree was being used. https://www.raspberrypi.org/forums/viewtopic.php?t=100066 Edit: changed /dev...

Re: Raspberry Pi 4 Thread - general discussion

A shim to convert from USB-C power supply to micro-usb (the other way around to the one on launch day) would mean RPT could drop the other power supply.
Is there a plan to do that, perhaps when stocks old the old supply run down?

another way to achieve similar result is to treat the Pi as something like a Smart TV and the TV as a dumb screen.

Re: Do I need a WVC1 License?

No.
Plus, if your needs do change in the future then you can add it later.

The MPEG2 licence is useful if dealing with TV recordings (in some countries) but the fastest RPi devices now seem to do an OK job handling that sort of material using software decoder (without the extra licence)
