I'm trying concatenate 2 video files with transition. I saw smpte element<br>
and trying to use smpte with filesrc but the command hangs. <br>
<br>
gst-launch-1.0 filesrc location=~/videos/small1.mp4 ! decodebin !<br>
videoconvert ! smpte name=s ! videoconvert ! x264enc ! mp4mux ! filesink<br>
location=./out.mp4 filesrc location=~/videos/small2.mp4 ! decodebin !<br>
videoconvert ! s. <br>
<br>
What am I doing wrong? <br>
