Complete, uncut console output missing, please remove the variables
when asking for support here.
"-r 25" is very wrong, you are feeding a value that only makes sense
for video into audio input and "-r" is wrong for x11grab input, use
"framerate".
(I thought the bitstream filter is not necessary anymore on the
command line.)
