I can get fmt-video, but not set it.
[EMAIL PROTECTED]:~# v4l2-ctl --set-fmt-video=width=768,height=576
ioctl: VIDIOC_S_FMT
[EMAIL PROTECTED]:~# v4l2-ctl --get-fmt-video
Format:
Type : Video Capture
Width/Height : 320/240
Pixel Format : BGR3
Field : Interlaced
Bytes per Line: 960
Size Image : 230400
Colorspace : Unknown (00000000)
Will try some googling about this problem too.
Is there anything else that I could check in a bash shell to help me correct
my HVR-1300 problem?
PS: I can change the resolution of my HVR display in TVTIME application.
