Re: LG TV reboots Raspberry PI 2

Many TVs aren't capable of providing the current that the Pi could use under load. That being said, every time I've used a TV USB port it's worked fine. I don't use this setup on a regular basis. I'd try it and see if it fixes the problem. In the reported cases, is it possible, the problem was the ...

Trev.
I had never given it any thought of using the TV's USB port to power the Pi. What sort of problems can develop if the ports are used?

thank you.

Re: Recommendation 300Mbps+ wifi dongle

There is no defined 150Mb limitation in the RPi. I was just saying there is no point is buying equipment that can go faster than many of the common adapters which max out at 150Mb/s. The RPi can't handle even that due to the USB bottleneck. Are there any test results showing when the usb communicat...

Re: Recommendation 300Mbps+ wifi dongle

Just a little sidebar note: I was unaware of the 150mb limitation of the Pi however, what I have noted in my streaming video situation is: if I use another Pi and the GPU, the latency is very low but using mplayer on Linux with out a graphic accelerator, the latency is as high as three full seconds ...

Negligible latency :)

Make sure hello_video.bin is in your path.

You may have to build it in /opt/ etc.

omxplayer to play stream from 2nd Pi

Thank you in advance,

I would like to use omxplayer on Pi#2 to play a video stream sent from Pi#1. On Pi#1, I am using the following

Code: Select all

raspivid -t 0 -w 640 -h 480 -o - | nc 192.168.1.10 5001
What is required on Pi#2 to play the stream using omxplayer? (hopefully, something very simple)

I stand corrected, IO is the real issue, even when accessing memory, the CPU has to slow down and wait for the results. :)

Sounds Interesting but I question the need to run that fast considering there is only 512 megabytes of RAM. That is the real bottleneck.

Re: Wifi adapter kills internet to ethernet when plugged in?

Is it possible your power supply is not supplying enough current to power the Wifi Adapter? I read, one amp is required to power everything including the Ethernet.
