Read it at the original source: ## Questions this post answers ### What is VirtIO Video and how is it used in production? VirtIO Video is a protocol for video codec virtualization. It is used in production on ChromeOS, and new Rust infrastructure is being developed to support it. Multiple companies are contributing to shape it into a robust video decoding solution, with ongoing upstreaming efforts and experimental ideas including a potential 'V4L2 on VirtIO' approach. _Developers working on virtualized multimedia pipelines track VirtIO developments like these on daily.dev._ ### How can PipeWire be used to secure multimedia pipelines on Linux? PipeWire can implement secure multimedia pipelines by enabling multiple processing points to run in isolation from each other while sharing the same hardware resources such as cameras and codecs. This replaces the traditional monolithic application model that required full exclusive hardware access, making complex and demanding use cases easier and safer to implement. _Linux multimedia engineers following PipeWire's evolving security model find relevant updates on daily.dev._ ## Similar posts on daily.dev - [Open Source in Prague: A week of talks, hands-on demos, and community\!](https://daily.dev/posts/open-source-in-prague-a-week-of-talks-hands-on-demos-and-community--w2mxqffp2) · Collabora Blog · 0 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#linux](https://daily.dev/tags/linux) [View this post on daily.dev](https://daily.dev/posts/april-brings-tech-events-aplenty-9sot3pl8j) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"April brings tech events aplenty","url":"https://daily.dev/posts/april-brings-tech-events-aplenty-9sot3pl8j","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/april-brings-tech-events-aplenty-9sot3pl8j"},"datePublished":"2026-08-11T08:57:23.692Z","dateModified":"2026-08-11T09:44:04.533Z","description":"Collabora is attending three tech events in April: PyCon US 2023 (20th anniversary) in Salt Lake City where Michał Gałka will talk about creating USB gadgets...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/2fb314ac05c4a09ed7ced73d7b927220?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/2fb314ac05c4a09ed7ced73d7b927220?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Collabora Blog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Collabora Blog","logo":"https://media.daily.dev/image/upload/s--ZGZ0FjqS--/f_auto,q_auto/v1786438306/logos/collabora?_a=BAMAMicg0","url":"https://daily.dev/sources/collabora"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/april-brings-tech-events-aplenty-9sot3pl8j","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"python,linux","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collabora Blog","item":"https://daily.dev/sources/collabora"},{"@type":"ListItem","position":3,"name":"April brings tech events aplenty"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/april-brings-tech-events-aplenty-9sot3pl8j#faq","mainEntity":[{"@type":"Question","name":"What is VirtIO Video and how is it used in production?","acceptedAnswer":{"@type":"Answer","text":"VirtIO Video is a protocol for video codec virtualization.
