From GStreamer Web APIs to C2PA: 5 Projects from our latest Innovation days

After two successful editions in 2024 and 2025, Fluendo’s Innovation Days returned this past autumn with a sharper focus on multimedia R&D and collaborative engineering. What started as an internal experimentation pilot has grown into a cornerstone event: three days of deep work at our Barcelona headquarters dedicated to innovation, collaboration, and rapid prototyping. For the 2025 Autumn edition, we gathered at our Barcelona offices, right before our company autumn party, making it the perfect moment to combine deep work with quality time together. The agenda spanned from initial pitches and environment setup on Tuesday to a full day of focused development on Wednesday, culminating in Thursday afternoon’s “Show-Time”, where teams presented their prototypes, key learnings, and proposals for next steps.

Why Innovation Days matter to us

Innovation Days are much more than a hackfest. They are company-wide, on-site events where we pause our day‑to‑day work and devote 100% of our time to exploring new ideas: from new products and technical R&D to internal tools, processes, and research experiments. But the purpose goes well beyond the projects themselves:

• Fostering innovation: We create space for ideas that don’t always fit into the regular roadmap but can shape our future offerings, technology stack, and workflows.
• Strengthening human connections: Fluendo operates largely remotely, so we deliberately use Innovation Days to bring people together in person—sharing meals, whiteboards, and spontaneous conversations that don’t happen on video calls.
• Reinforcing cross‑functional collaboration: Teams are formed across departments and roles, mixing engineering, research, product, marketing, and operations.
• Meeting face to face: Organizing Innovation Days the same week as our company gathering makes it easier for people from different locations to travel, spend time together, and build trust beyond screens. In short: it’s an event about ideas and impact, but also about people and connection.

The 2025 projects

The 2025 Autumn edition delivered a diverse set of projects, ranging from multimedia training automation to low‑level streaming innovation and content authenticity. Below is an overview of the all the projects we worked on.

1. GStreamer Training Creation with Slidev

This initiative focused on streamlining the creation and maintenance of GStreamer training materials. By leveraging Slidev and related automation tools, the team aimed to simplify the process of generating, updating, and publishing slide decks. Key goals included: The goal was to:

• Reduce friction when updating training content.
• Enable more modular, reusable, and version‑controlled slides.
• Make it easier for different team members to contribute.

2. Automatic Camera Control – InnoDays Prototype

The InnoDays project served as a test bed for a pioneering Automatic Camera Control system. This initiative explored ways to make camera behavior smarter and more adaptive across diverse filming and photography scenarios. Key objectives of the project included: This project investigated how to:

• Use metadata and environment cues to drive camera decisions.
• Improve the experience of automated or semi‑automated capture workflows.
• Integrate proof‑of‑concept control logic into existing pipelines.

3. GStreamer Encoder Statistics

This project, “GStreamer Encoder Stats”, focused on observability for encoding workflows. The goal was to gain better insights into how encoders behave in real scenarios so teams can:

• Diagnose performance issues more easily.
• Tune parameters for quality, latency, and resource usage.
• Build dashboards or tools on top of structured metrics.

4. GStreamer Web API

Continuing our long‑term work around GStreamer on the web, the GStreamer Web API project aimed to make it easier to integrate GStreamer capabilities in web environments. The team explored:

• API designs and abstractions that make sense for web developers.
• How to expose powerful media features safely and ergonomically.
• Integration patterns with existing web frameworks and tooling.

5. Cuckoo: Multimedia Content Authenticity and Provenance

The Cuckoo initiative addressed one of the most pressing challenges in digital media today: authenticity, provenance, and trust, especially in the era of generative AI. Building on C2PA (Coalition for Content Provenance and Authenticity) standards and related industry efforts, the project explored:

• How to cryptographically sign and verify multimedia content.
• How to handle content transformations where metadata might be stripped or altered.
• How to extend this to live streaming, where standards are still evolving.
• The broader confidence crisis in digital information.
• Regulatory context (EU AI Act, eIDAS, California AI Transparency Act, etc.).
• The current maturity and ISO fast‑track path of C2PA.
• Technical approaches: manifests, signing, embedding, soft binding, and live streaming gaps.

Outcomes: beyond prototypes

By the end of the three-day InnoDays event, each team delivered a 15-minute presentation highlighting their progress, accompanied by links to code repositories, demos, and supporting documentation. They also outlined next steps, identifying how their work could evolve and connect to product development, research initiatives, and internal process improvements.

Equally significant were the human and organizational outcomes. Team members who rarely collaborated spent three days working side by side, sharing context, ideas, and diverse perspectives. This fostered cross-team collaboration, encouraged knowledge exchange, and strengthened connections between disciplines, creating lasting value beyond the prototypes themselves.

Looking ahead

The 2025 Autumn Innovation Days demonstrated once again that dedicated time for innovation drives results. By clearing calendars and focusing on exploration, teams were able to turn ambitious ideas into tangible prototypes in just a few days. The event also underscored the importance of on-site collaboration: for a largely remote organization, spending three days together in the same physical space strengthened relationships, trust, and cross-team communication.

Finally, we saw how short experiments can have long‑term impact, as many of the projects from this edition are already informing roadmaps, research directions, and open‑source work. These learnings feed back into how we plan future editions: from scope and planning to team formation and long‑term follow‑up.

Until the next edition, if you’re curious about our innovation culture or want to learn more about any of the projects mentioned here, don’t hesitate to reach out.
