This document summarizes updates and the roadmap for Paella Player and its integration with Opencast. Key points include: Paella Player version 5.2.11 includes new features like multiple audio sources and zoom capabilities. Version 5.3 will run as an Electron app and support improved plugin registration. Strategically, Paella will replace Theodul as the primary Opencast video player. The Paella team is focused on tighter Opencast integration and providing a stable player for the Opencast community. The roadmap includes further Opencast features, accessibility improvements, and supporting community development.

9. HLS is our recommendation for streaming
• Improvements and bug fixes in HLS.
• HLS streams in Safari for macOS now uses the native hls player.
• HLS streams limited to one simultaneous stream on iOS, to prevent
memory problems on old iOS devices (configuration tag)
• MPEG-DASH not working in Apple devices
• File-based Multiple quality support problematic

10. Paella & Electron
• Electron is a a library to build cross platform desktop apps with
JavaScript, HTML, and CSS
• Paella 5.3 runs with electron
electron <paella root folder>main.js
• It could be a self contaned file with an installer

11. Use cases
• Easier Debugging
• Offline player

12. Opencast and Paella

13. Strategic direction
• As today, Theodul won’t be developed further
• Paella will try to fill Theodul’s place in the OC ecosystem
• Focus in Opencast integration
• Provide a stable environment for OC adopters
• Provide features from Theodul
• Community development & Issues management

14. Paella Team

15. Paella & Opencast up to OC 4.X
• Two Github Projects
• Paella: A standalone dual stream player
• Paella-opencast: Bindings & plugins for using paella in Opencast
• Instalation process
• Clone paella-opencast
• Configure paella-opencast
• Compile
• Drop the .jar bundle

16. Paella and Opencast 5.0
• License change to ECL
• Opencast-paella disappears and added to the OC codebase
• Paella 5.3 release
• One configuration file per tenant (/etc/paella/<tenant>/config.json)
• Update to the plugin API in the line of allowing external plugins
• Working towards (like theodul)
• Core in a bundle (will be paired with paella-standalone)
• Plugins in different bundles
• Use OC configuration files

17. Update in the Plugin system (only for devs)
• Only if you have your own plugins and from 5.3 on
• Using this method, it was very difficult to control the plugins life cycle,
because Paella Player don’t know when the plugin is instantiated.
• To improve the life cycle control, from Paella Player 5.3, the plugins
are instantiated using a function that receive a closure as parameter
• You will have to (slightly) update your plugins

el_doc/paella_5_3_plugin_migration.md

18. Issues management
• Error in Opencast bindings should be reported in Opencast
• We are going to close paella-opencast
• Issues for the paella core should be in the paella core site
• We will move issues between sites and reference both
• Paella team is dealing with the extra workload

19. Community development
• We want to support community development of Paella
• So we look for:
• Freezing APIs
• Having a clear(er) Roadmap
• Supporting bugfixing
• So, if you are looking to develop something in/for Paella
• Please do so
• If you want, we can chat about the best internals of paella for your use case
• Make a pull request

20. Paella 6 (and beyond) Roadmap
• Opencast integration features
• Working towards N-streams
• Disable a stream when not used
• Updated StreamManager class in the video container
• Better profile management
• Low-hanging fruits
• Language code from 2 to 4 letters (en -> en_us)
• Refactor for accesibility
• Specific projects (upon request)
