- create a crate for graphview/node/port
- Implement pipeline unit test
- Control the connection between element
- unable to connect element with incompatible caps.
- Implement graph dot render/load
- Add probes on each pad to monitor the pipeline
- Render a media file
- Offer compatible element to a pad (autorender)
- Display tags/meta/message detected
- Change TreeView to ListView
- Implement zoom on the view (https://gitlab.gnome.org/World/obfuscate/-/blob/master/src/widgets/drawing_area.rs)
- reopen the last log on prematured exit (crash)
- Play/pause should be prevented until the pipeline is ready
- Filter the elements by class/rank etc.
- double click on node/pad open the properties
- Combo box is not well selected if the value is not linear such as flags. See flags in playbin
- opening a graph file can lead a different behavior in the pipeline. See videomixer graph where the zorder on pads is not correctly set to right one.
