Re: no Audio Video with web.skype on Chromium

In fact ... skype works with audio ... you can send audio chat messages.

The problem is with videoconferences. And my test on Linux was using Chrome, not Chromium. So ... it is a Chromium limitation more than a Raspberry Pi one.

Re: no Audio Video with web.skype on Chromium

This works with Ubuntu on a PC ... it is not a Windows "issue" ... just on Rasperry doesn't work but I will continue testing to see why.

Re: Microsoft Teams Support

I was thinking on this type of setup, to freed my Mac from the hassle of running the extremely heavy Teams program. Thanks for all the testing, I can proceed with the idea :-) As a reference, when using Teams in a Mac Mini late-2012 with i7 CPU and 10GB RAM, (2 + 8), the machine stops working normal...

Re: Questions about porting from C to C++

Just a last detail here. When you make some C++ stuff, take care on what standard are you following. In general the main differences are when we have the C++11 standard, adding the functional paradigm to the language. This are accumulative on top of the C++11 towards our current C++20 standard versi...

Re: Questions about porting from C to C++

Yes, the compiler must be happy reading the right things. And that is make when calling the headers (the source files must stay in the original C format and extension). #ifdef __cplusplus extern "C" { #endif // your C definitions OR #include <your C header files> #ifdef __cplusplus } #endi...

Re: Questions about porting from C to C++

Nah, there is no rule that says you have to use inheritance, polymorphism, template meta-programming, exceptions, and every C++ feature in your programs. In fact Bjarne Stroustrup himself says that C++ is not all about Object Oriented Programming (OOP). He will tell you that C++ is a multi-paradigm...

Re: Questions about porting from C to C++

I see you have been advancing in your efforts to jump into the C++ wagon. However, from my point of view, the right thing to do is to do nothing and to stay on C as the library was designed with C in mind. Something that can be done is just a "wrapper" to present the library behavior with ...

Re: Commercial Use of the Pi

Well, the Zero wasn't really designed as you say, it was designed, really, to see how cheap it could be made. In fact the Zero isn't that great for IoT applications for one big reason - power consumption is too high. It cannot be battery powered for any length of time so needs to be hard wired to a...

There is no problem when somebody creates a device with a distribution restriction. However, there is a real issue when an expectation that can't be fullfilled is created. When the Zero device appeared at $5, the Raspberry Pi was already a "best seller". Then the message was very clear: th...

Re: USB boot now working on Pi3

One question to the forum members. Did somebody already test this with the WD Pi Drives? They are supposedly designed to work well with the RPI machines. What I see is that the RPI didn't born with this functionality ready at hand, and could be possible that, although in some cases it will work, the...

Re: USB boot now working on Pi3

Interesting finding, Chas123. Let me see, you used a 5A power adaptor (twice the recommended capacity for the RPI). Although I don't have so powerful adaptor per port at hand, I made another test with 12A power adaptor (this provides 2A on each of its 6 USB ports). The same result as before. Then, I...

Re: USB boot now working on Pi3

I noticed a new version in the next branch (Aug 30th), so I made a new test today.

Memory issue : fixed.

5 boots ... zero problem
1 boot ... colored frozen screen
1 boot ... zero problem

Is there something in the RPI3 (the machine itself) that becomes unstable after some continuous reboots?

Hi CaptManiac. There is something you could try ... although I don't know if this will break some dependency. 1) Check what is your Kernel version (uname -a). If it is 4.4.16 or greater, then your /boot partition was updated with the apt-get upgrade command and probably you lost the special bootcode...
