Description

Hi..
I am trying to stream with ffmpeg using the device XI006AEPRO which is functionally a 6 channel AV capture card.. I have installed the driver and can watch video from connected devices through vlc.. When trying to use the device with FFMPEG (dumping file or streaming live) it shows the error message saying..

"[video4linux2,v4l2 @ 0x2eb09e0] ioctl(VIDIOC_G_PARM): Inappropriate ioctl for device
/dev/video0: Inappropriate ioctl for device"
Command line along with output is provided below..

The same thing happens even with the newly compiled FFMPEG..
