Interesting, sorry about that. I only ran git send-email once, but I did notice that the messages arrived out-of-order in Patchwork and the list archive--maybe there was a delivery issue somewhere and either Google or the list server re-sent the messages? > > +@item > > +Grab and record the input of an Apple iSight, using the shorter options. > > +@example > > +ffmpeg -f libdc1394 -pix_fmt uyvy422 -s 320x240 -r 30 -i auto out.mkv > > +@end example > > The shorter options are deprecated and aren't strictly speaking, private > options of this device, so remove this example.

While there isn't an inherent restriction, devices only support a limited number of video modes, and in each of those modes only certain frame rates are supported. I added this example to demonstrate that other video modes/frame rates could be used, but since the other examples use this resolution/frame rate combo this example does seem a bit redundant, so I'll remove it. > > +@item > > +Grab and record the input of a specific Apple iSight. > > +@example > > +ffmpeg -f libdc1394 -pix_fmt uyvy422 -s 640x480 -r 15 -i > > 0x000a270004106ea3 out.mkv > > +@end example > > Replace with device options.
