When setting up gst-rtsp-server, the RTSP reciever will only show the<br>
content of the first frame, though the server keeps sending frames.<br>
<br>
I use following pipeline:<br>
<br>
/imxv4l2videosrc device=/dev/video0 imx-capture-mode=5 ! tee name=tp tp. !<br>
queue ! imxipuvideotransform ! *jpegenc* ! fakesink sync=false tp. ! queue !<br>
imxipuvideotransform  ! imxvpuenc_h264 bitrate=0  ! rtph264pay name=pay0<br>
pt=96 config-interval=1/<br>
<br>
The strange thing is, without /jpegenc/ in the first 'tee' branch everything<br>
works fine (*)<br>
<br>
Any help is appreciated!<br>
