As Tim said, it is certainly possible to do it without playbin, but more 
complex. For example, I've implemented gapless playback without playbin, 
but for audio-only playback. I used the concat element. I couldn't use 
playbin, because I had to be able to prefetch data for the next stream 
properly (for example, start the prefetch 10 seconds before the current 
stream ended). With concat, you can notice when the switch happened by 
installing a pad probe on its srcpad that checks for a stream-start event.
