title: Gstreamer Tee with different capabilities on each branch
body: <p>I have a gstreamer pipeline similar to this.</p>
  
  <pre><code>                              Queue -&gt; videoscale -&gt; videosink
                               /
  appsrc -&gt; h264_decoder -&gt; Tee 
                               \ 
                                Queue -&gt; jpegenc -&gt; multifilesink
  </code></pre>
  
  <p>How does Tee work with regard to capabilities on the decoder pad? Is it possible to set different capabilities on the two branches?</p>
  
  <p>Specifically, is it possible to set two different framerate? Filesink stores at 1 fps, and videosink displays at 30 fps.</p>
  
  <p>I am using the following command line to test.</p>
  
  <pre><code>gst-launch-1.0 -e \
      filesrc location=${1} ! queue ! qtdemux name=d d.video_0 ! h264parse ! avdec_h264 ! tee name=t \
                         t. ! queue ! videoscale ! 'video/x-raw,width=(int)960,height=(int)540' ! autovideosink \
                         t. ! queue ! 'video/x-raw,framerate=1/1' ! jpegenc ! multifilesink location=out/img1_%03d.jpeg
  </code></pre>
  
  <p>But I get an 'Internal data flow error' and 'reason not-linked'.</p>
