It works with MPLAYER. Have to do some tweaking as picture is way too dark.
You are not giving the proper camera name in the commands. The default names will work for your first camera:
But I am wondering why you want to use mpv if mplayer works for you. Mpv is the recplacement for mplayer in the latest Debian release.
I am pretty sure if you change the mpv command to:
Code:
mpv tv:// --wid {XID} --vf-add=drawbox=-1:2:-1:240:t=1 --vf-add=drawbox=2:-1:320:-1:t=1 --no-border
it will work.
So it;s a case of using the proper camera name. You can get a list of all the video capable hardware if you do a
Code:
sudo ls -la /dev/video*
You can also find the proper name if you do a
with unplugged camera and then plugin the camera and do another
. Your camera will be the last hardware in the second list (or in the difference between the first and second dmesg).
For your information, these are pure cosmetic:
Code:
--vf-add=drawbox=-1:2:-1:240:t=1
adds a rectangle on the camera image in such a way that only the ' inner' lines show up.
Code:
--vf-add=drawbox=2:-1:320:-1:t=1
same
The purpose of the rectangles (that form a cross on the image) is to have some crosshairs to better positon the spindle. The location of the crosshairs can be manipulated with the parameters in case your camera has an offset to the spindle axis.
makes the cameraview in the tab in gmoccapy display without an ugly border.
There are many more command line parameters you can pass to mpv,

Hope this helps.
