Hello All,
I've been trying without success to capture video from a PixelView
XCapture USB card, using the cx231xx driver module and ffmpeg on a
CubieBoard2 (A20).
After loading the driver module successfully, I run ffmpeg that captures
one single empty frame. When I quit ffmpeg the kernel issues the following
error messages:
cx231xx #0: UsbInterface::sendCommand, failed with status --71
cx231xx #0: UsbInterface::sendCommand, failed with status --71
cx231xx #0: cx231xx_stop_stream():: ep_mask = 8
cx231xx #0: can't change interface 4 alt no. to 0 (err=-71)
I'm using kernel version 3.4.103, and buildroot to build the root file
system. V4L2 where compiled as modules. Some extra information about my
system are provided further down.
Thanks in advance. Any help would be much appreciated.
Regards,
Weber
