Tom,<br><br>you could simply write a gstreamer application.<br>In the capsfilter change the farmerate when needed, this will trigger caps renegotiation.<br><br>But had never tried, I think this has to be properly supported by the downstream encoder plugin (not sure if jpegenc supports that or not).<br>

<div>I use <br><font color="#009900">gst-launch filesrc "location=video/1.MPG" !

port=$portNumber <br></font>to stream a video and can change the video frame
rate in this way.</div>
<div>But in this way the frame rate is fixed (i.e., framerate=25/1 here).
<br><br>I want to change the framerate in REALTIME when video is PLAYING --- during the
streaming of this video, I can change the framerate anytime I want.</div>
<div> </div>
<div>Someone has replied that I can use Python to get dynamically
changing.</div>
<div>
<div>But I am a new user of Gstreamer and my project is due next week
:(<br>I searched those python examples but did not get information that I can use for my problem :(<br><br></div></div>
<div>Anyone can give me a simple example of this kind of Python
script?</div>
<div>Thanks you in advance!<br><br>Tom<br></div></font></font>
