[vlc] changing transcode parameters on-the-fly

[Gun Akkor]

Hello,

I am starting VLC with the following command line on a 
Linux machine:

vlc v4l:// :v4l-vdev="/dev/video0" :v4l-adev="/dev/dsp" 
:v4l-norm=1 --sout '#transcode{vcodec=h264, 
venc=x264{tolerance=0.05, analyse=fast, qp=26, me=hex}, 
acodec=mpga, ab=32, deinterlace=blend, vb=32, height=144, 
width=176, fps=12}:duplicate{dst=std{access=udp, mux=ts, 
dst=192.168.200.1:1235}}' -I dummy --extraintf rc 
--rc-unix "/tmp/video0.vty" > /tmp/video0.log 2>&1 &

which allows me to capture video, transcode it using the 
x264 library and to stream it UDP to a local subnet while 
keeping a rc unix-socket interface open. This part works 
perfectly. What I would like to ask to the list is whether 
there is a way to change any of the transcoding parameters 
on-the-fly without using a graphical interface, and 
without stopping/re-starting the current VLC interface. It 
is possible to adjust the size or fps parameters of the 
vcodec for the running stream?

Any suggestion is greatly appreciated.
Regards,

GA
