Hi, I have a new 16:9 monitor.
What is the best way to configure ivtv for this? Can I get ivtv to create 16:9-optimized output video, where 16:9 shows fill the whole thing, but 4:3 shows have "black bars" on the sides? That would be ideal, because right now, I have ivtv set at 720x576 and 16:9 shows have black bars on the bottom and top, while 4:3 shows fill the whole thing. I guess this means less quality for 16:9 shows, right? ivtvctl used to have a setting for configuring aspect ratio (-c aspect=?), but alas, no more. http://ivtvdriver.org/index.php/Ivtvctl_old I also looked for an aspect-ratio setting in v4l2-ctl but found none. Is this more of a mythtv question? I'm thinking it can't be because then mythtv would have to constantly be monitoring the input mpg and change aspect ratios dynamically e.g. as programming changes, commercials come and go, etc... I also tried configuring ivtv to capture still at 576 lines, but at a width = 576 / (16/9) = 1024, but that seems not to be possible. $ v4l2-ctl -v width=1024,height=576 ioctl: VIDIOC_S_FMT $ v4l2-ctl -V | grep Width Width/Height : 720/576 Instead I experimented with a width of 720 but less height. Still, I get black on top/bottom for 16:9 shows and 4:3 shows fill the whole thing. So right now, in mythtv, I need to manually toggle apsect-ratio overrides when I switch channels or when a channel changes aspect ratio. With my old 4:3 screen, the current situation was perfect. 16:9 shows have black top+bottom and 4:3 shows fill the whole thing. What is the way to go about this?
