I just discovered the following module options:
modinfo ivtv:
parm: ivtv_yuv_mode:Specify the yuv playback mode:
0 = interlaced
1 = progressive
2 = auto
Default: 0 (interlaced) (int)
parm: ivtv_yuv_threshold:If ivtv_yuv_mode is 2 (auto) then playback
content as progressive if src height <= ivtv_yuvthreshold
Default: 480 (int)
modinfo ivtvfb:
parm: osd_laced:Interlaced mode
0=off
1=on
default off (bool)
Are these options related to the YUV device (/dev/video48) ?
What is the difference between ivtv_yuv_mode and osd_laced ?
(The name "osd" may be misleading like osd_depth, osd_upper, osd_left,
osd_yres, osd_xres. The last 5 are are for the size of the /dev/video48
output.)
Should I set ivtv_yuvthreshold to 576 if I have a PAL card (720x576) ?
Should ivtv_yuv_mode be moved from ivtv to ivtvfb ?
Are there ioctl (v4l2 or framebuffer) to set interlaced/progressive and
threshold?
Greets,
