@orikoon, thanks for the tip. Are you building a cool project that uses the USB API. I’d love to hear about it. Can you start and stop the video ptpcam? I’ve had some problems stopping the video with ptpcam on Raspberry Pi jessie. If you have it working, can you let me know your OS, version of OS, and version of ptpcam you are using.
I’m using Ubuntu 14.10 and libptp2 1.2.0. Actually, my project does not use the video features but I tested the following command and it worked nicely.
First, To set video mode :
ptpcam --set-property=0x5013 --val=0x8002
And start shooting :
ptpcam -R 0x101C
Finally, stop shooting :
ptpcam -R 0x1018,0xFFFFFFFF
I hope this may help you!
