Hello gstreamer lovers!
I'd love to get video transitions working from the ges-launch command line. Tried with several video formats (ogg/theora - mp4/x-raw): no luck (Ijust get a regular cut: direct switching from one clip to the other). even with test-clips it doesn't work for me (no transition effect observed): ges-launch-1.0 +test-clip red duration=5 +transition crossfade duration=2 +test-clip blue duration=5 is my syntax wrong? am I missing something? I use a self compiled 1.16.0 gstreamer version, and of course I can provide any debug / log Thank you for reading this! cheers!

Hello, Transitions are automatically added when clips overlap, you can just do: ges-launch-1.0 +test-clip red duration=5 +test-clip blue start=2 duration=5 and there will be a transition from the second second to the fifth.
