Multimedia

Multimedia processing is one of the most demanded and complex tasks in computing. It traverses all the software stack, ranging from the kernel up to the end-user application. Igalia has a strong team of multimedia experts with experience in all the layers of the stack, both on desktop environments and embedded devices.

GStreamer is the framework of choice for Linux-based multimedia and it has been powering multimedia embedded solutions for many years now. Our multimedia team includes many experienced GStreamer developers who are very familiar with the framework internals and contribute to its core and to many of its plugins.

We are the main developers and maintainers of the GStreamer-based multimedia back-ends of WebKit that are used by many of its ports, including WebkitGTK+ and WebkitEFL.

We also have experience bringing hardware acceleration to GStreamer, writing plugins and infrastructure required to use hardware accelerated multimedia such the case of asymmetric processing of media using multiple cores.

Beside media playback and recording, we are pioneers in digital media content discovery and browsing, and as a result, we are the main developers and maintainers of Grilo, a framework designed to provide application developers with tools that make digital media content integration extremely easy, scalable and highly maintainable.

Igalia can help you build top-notch solutions for media centres and players targeting TV, Set-top boxes and other multimedia enabled devices based on open source technologies. Our multimedia team can lead specific parts of the software development, provide advice and insight on the solutions used, join an in-house team to leverage its strenghts or help companies align their work and needs with the open source community.

Support GstContext for VA-API elements

Since I started working on gstreamer-vaapi, one of what’s disappointing me is that vaapisink is not so popular even though it should be the best choice on vaapi installed machine. There are some reasonable causes and one of the reasons is probably it...

Libva-rust(libva binding to rust) in development stage

Since Rust language appeared in the world, I felt strongly this is the language I should learn. This is because: Rust guarantees to prevent from common bugs in C/C++ such as memory corruption and race condition, which are very painful to fix whenever...

bin: Fix use-after-free issue in gst_bin_add()

gst_element_post_message() takes ownership of the message so we need to increase its refcount until we no longer require access to its data (context_type). https://bugzilla.gnome.org/show_bug.cgi?id=797099
