<br>
I also tried your suggestion...I typed into my command line the following<br>
pipeline:<br>
<br>
gst-launch-1.0 autovideosrc ! image/jpeg, width=640, height=480 ! jpegenc !<br>
<span class="gmail-">rtpjpegpay ! udpsink host=127.0.0.1 port=5200<br>
<br>
</span> I received the following message output:<br>
<br>
"WARNING: erroneous pipeline: could not link autovideosrc0 to jpegenc0,<br>
neither element can handle caps image/jpeg width=(int)640<br>
height=(int)480"...I re-typed the command pipline removing the<br>
"width/height" information and got the same response back from the<br>
program...<br></blockquote><div><br></div><div>The sink video caps for jpegenc has to be 'video/x-raw' as you can check with 'gst-inspect jpegenc'. Nicolas probably got it backwords as the 'src' side of 'jpegenc' is the one that accepts only 'image/jpeg'.</div><div><br></div><div>I bet your first 'negotiation error' was caused by your videosrc not providing video with the measurements you requested.
