- External Battery Pack with RPi + Camera
Last time, I was not able to run the RPi camera board at 1080@30 with the battery pack I have.
I tried to measure the voltage and current using multimeter.
However, my test condition was not great, and long cable caused too much voltage drop to make RPi work properly...
Hope I have good test tools... it would be nice to make USB current monitor using tiny MCU...
- Using PS Vita Portable ChargerI had Vita charger which is capable to output up to 1500mA and tested again.
TX (RPi)raspivid -t 999999 -o - | nc [insert the IP address of the client] 5001
[Path to nc.exe]\nc.exe -L -p 5001 | [Path to mplayer.exe]\mplayer.exe -fps 31 -cache 1024 -
This time it worked!
It was the power issue.
I assume average current is ok but I am guessing the peak current was actually causing issue...

WiFi video streaming was tested using Raspberry Pi camera board and Vita portable charger.
Video image was displayed properly and response was less than fast enough.
