Andy,

it's not your mac.

I occasionally post via iOS if travelling, but mostly from an available RPi, & for several months it's been like this. The latest failure for my posting being in this short thread:

Pronto! Can you elaborate? For instance, do you want to run the X desktop, or just a command line (terminal) interface (handy if this will be your ONLY application for this RPi)?

Re: Why must the raspberrypi be so proprietary?

If you think the RPi GPU is "secret" you clearly have never worked with SoC's containing Realtek® GPU's. For a while I spent some time with their MIPS® based ones (ARM now own a lot of the MIPS portfolio). Only people that bought the Realtek SDK had any access to GPU info', & it was several months e...

Re: RANDOM VIDEO PLAYER FOR ART INSTALATION

In that case, a simpler application will do the job without gaps, providing your source videos are in .h264 form, or if mpeg4 you can quickly convert them on your RPi via something like gpac. The app's source code is on your Raspbian µSD card in: /opt/vc/src/hello_pi/hello_video/ You'll need to buil...

Hello Hermann. I don't use the usual linux grabbing tools, as they are usually unaware of openmax, & mmal, so I don't know about the virtual stuff you mention.
