I trying to stream this video to a Raspberry Pi

It's probably because it's a live stream and not a video.

Well I totally agree with you. This is the first thing I do after installing raspbian on a Pi of mine.

It depends on your programming skills. :)
I would personally use QtQuick for something like that, but it's quite advanced programming.

Hey,

Is there any other device on the CAN bus?
I think the mcp2515 doesn't receive an acknowledge from any other device, so it resends the message over and over :) .

Re: Use a button on the input pin.

1: This circuit will work fine, but doesn't have any protection. Here, the input is pulled low when you press the button, so 0 (low) is pressed and 1 (high) is released. 2: This is the same as 1, but instead of being 1 (high) when released, it's 0 (low) and vice versa. 3: The extra resistor is for w...

SPI wrong data out

Hey everyone, I have a little problem using the SPI in bare metal C. I have it working in assembler, but I can't seem to find the fault in my C code. The problem is that when i send data over SPI, on the data line, there are only 'spikes' and not the actual data. http://i65.tinypic.com/2927d6f.jpg T...

Re: Pi 3 in an old laptop. Is this madness?

I think you should need one with an IC otherwise it's probably just wired directly. A good word to use when searching is 'active' which means there is some circuitry involved and not just wiring.

I haven't used one myself so I can't give you any good recommendations.

Re: Model A ethernet?

You can use a USB to ethernet adapter.
As the Ethernet/USB hub IC isn't populated on the RPi A, you can't just solder on the Ethernet port.

If you rely wanted, you could solder the Ethernet IC on, but I don't think it's worth the effort/price. :)

Re: Have experience with Raspberry Pi? Interested in IoT?

I like the idea of connecting iot with the raspberry pi, without using windows.
As there isn't much software running on RPi linux to easly connect your home to your phone. :)

I have a good knowledge of the Raspberry pi and I like to chat with you (team) about it. ;)

Re: Gigabit ethernet on Raspberry 3

The ethernet port on the raspberry pi 3 only has 100 Mbit capacity.
Also a 1Gbit usb connector won't work, as the USB bandwidth is only 480Mbit.

Re: Screen size setting

I think it has to do with the resolution you use. Sometimes the GPU doesn't accept a specific resolution. I use 1920x1080 which works fine. You could also try 640x480 to test the code. If this works, it's probably an unsupported resolution. I compared it with code I have running fine, and I don't se...

Is it a big job to strip the Ethernet port and replace the double stacked usb's with single's to minimise the thickness of the board? It depends on how good you can solder and how good your tools are. But it shouldn't be to difficult tho. https://learn.adafruit.com/diet-raspberry-pi/overview Laurens
