Description Mark Nauwelaerts 2006-10-29 22:12:56 UTC 
The example pipeline given in videomixer (which works ok) is
videotestsrc pattern=1 ! video/x-raw-yuv, framerate=\(fraction\)10/1, width=100, height=100 ! videobox border-alpha=0 alpha=0.5 top=-70 bottom=-70 right=-220 ! videomixer name=mix ! ffmpegcolorspace ! xvimagesink videotestsrc ! video/x-raw-yuv, framerate=\(fraction\)5/1, width=320, height=240 ! alpha alpha=0.7 ! mix.

However, if the 5/1 framerate is replaced by e.g. 7/1, this inputs stalls, and only a still frame is mixed with the other stream.
