For some reason, my call of v4l2-ctl is not working. I'm trying to
change width/height to the standard NTSC 640/480, but it fails:
[EMAIL PROTECTED] ~]# v4l2-ctl -v width=640,height=480 --verbose
VIDIOC_QUERYCAP: ok
ioctl: VIDIOC_S_FMT
ioctl: VIDIOC_S_FMT failed
[EMAIL PROTECTED] ~]# v4l2-ctl -V
Format:
Type : Video Capture
Width/Height : 480/480
Pixel Format : MPEG
Field : Interlaced
Bytes per Line: 0
Size Image : 131072
Colorspace : Broadcast NTSC/PAL (SMPTE170M/ITU601)
Anyone know why this might be, or if I'm wrong, and 480x480 is the right
setting?
Here's the extra info:
