## GStreamer

- Cross platform open source pipeline based multimedia framework
- By default on all Linux distributions
- Used in many industries

NOTE:
- Embedded devices/TVs
- Broadcasting industry
- Medical industry
- ...

---

## GStreamer Editing Services

- High level APIs for video editing

- GESTimeline
- GESProject
- GESLayer
- GESTrack

NOTE:
- Written in C with Python/Javascript/rust bindings

---

### OpenTimeline IO integration

- Added an `xges` OpenTimelineIO adapter

→ We can convert editorial cuts information from and to the GES serialization format

---

### Support in GES

- `GESOtioFormatter`

→ Any format supported by OpenTimelineIO can be loaded in GES

NOTE:
- Implemented in python using PyGObject
- Plans to port it to the C++ API when possible

---

### Support in GStreamer

- Wrote the `gesdemux` GStreamer element
- Implemented `typefind` function to detect file formats supported by Otio

→ Files supported by OpenTimelineIO can be used as any media files in GStreamer

NOTE:
- Implemented in python using PyGObject

---

### Future

- Move to the the Otio C++ API
- Add support for nested timelines in the Otio formatter

Thanks!
