Thanks Matt,<div><br></div><div>What if I want to do the same thing with an RTSP stream? I am using the test-launch.c app and passing my plugin as argument i.e.:</div><div><br></div><div><span style="font-size:11.0pt;line-height:115%;font-family:"Calibri","sans-serif""><font color="#990000">./TEST

For this case I think you'd need to encode it twice, once at 640x480 and again at 320x240. So you'd have to move your tee up the pipeline:<div><br></div><div>gst-launch v4l2src ! tee name=t. ! <encode@640x480> ! <udpsink> t. ! <encode@320x240> ! <filesink><br>

You'll want to use the videoscale element along with a caps element:<div><br></div><div>gst-launch videotestsrc is-live=TRUE num-buffers=90 ! tee name=t ! queue2 ! videoscale ! ffmpegcolorspace ! video/x-raw-rgb,width=640,height=480 ! ximagesink sync=false t. ! queue2 ! videoscale ! ffmpegcolorspace ! video/x-raw-yuv,width=320,height=240 ! theoraenc ! matroskamux ! filesink location=/tmp/test.mkv</div>
