Here's a speculative question about the possibility of automatic detection of aspect ratio.
While using mplayer or xine to play /dev/video, the aspect ratio of the displayed video is automatically adjusted on the fly when one changes ctl_video_aspect between 4x3 and 16x9. I suppose mythtv does this too, but I have not tried. Anyway, my conclusion is that ctl_video_aspect sets the aspect ratio flag embedded in the MPEG-2 stream coming out of the pvrusb2. It seems to me that it would be nice if the pvrusb2 device could automatically detect the aspect ratio of the incoming signal (whether broadcast, composite or s-video) and set the flag accordingly. At present, I have to visually decide what the intended aspect ratio is and manually set ctl_video_aspect, which is inconvenient. I am particularly interested in having this functionality for composite and s-video. (Analog TV broadcasts have stopped here). But, I have to admit that I don't even know if composite or s-video contains information about aspect ratio. Would someone care to comment?
