How media codecs shape our digital world

Media codecs significantly impact our daily lives by enabling the efficient streaming, sharing, and storage of high-quality audio and video content across devices. This technology makes digital communication and entertainment faster and more accessible.

Knowing the types of codecs

Codecs are classified based on function and purpose. Some focus on audio or video, while others function as encoders, decoders, or both. They can be lossy, compressing files by permanently removing some data to reduce file size, or lossless, preserving all original data by removing only unnecessary metadata. Additionally, codecs can be software-based or hardware-based, with hardware codecs designed for optimized performance on dedicated devices.

  • Audio codecs: WMA, AC3/EAC3, iLBC, LPCM, MP3, AAC/HE-AAC, ADPCM, etc.
  • Video codecs: WMV, MPEG-4, MPEG-2, DivX3, H.264/AVC, H.265/HEVC, etc.

The table here lists the main libraries for HW accelerated encoding/decoding.

Open-source vs. Proprietary options for multimedia applications

Regarding accessibility, codecs can be open-source or proprietary, with licensing requirements that impact their integration into various products and services. Because of these differences, we offer a deep understanding of codec technology to help make the right choice for any multimedia application. For more details, please read our article on the Differences Between GPL and LGPL for Licensed Software. We also developed Fluster, an open-source tool designed to streamline codec testing. Fluster is a Python-based framework for decoder conformance testing, making verifying codec compliance and functionality easier.

Low-latency and adaptive protocols for real-time applications

Low-latency streaming protocols are essential for real-time applications, where minimizing delay is critical. With expertise in protocols like WebRTC and the newer WebTransport, we enable seamless, low-latency communication for interactive and live-streaming experiences.

Additionally, we specialize in HTTP-based streaming protocols such as HLS and DASH, which are widely used for delivering adaptive, high-quality media over the Internet. This blend of real-time and HTTP streaming protocol experience allows us to create solutions optimized for various streaming needs, from live broadcasts to on-demand content delivery, ensuring a smooth and responsive viewing experience.

Capture the best shots and metadata with our GStreamer PoC

What is this about?

We had to develop a proof of concept in one of our latest Consultancy projects. That PoC gives the client a simple but valuable tool to perform the following actions:

  • Include the camera metadata in the snapshots.
  • Get the sharpest frame in a window of N possible.

But how these two actions are integrated in the PoC? Well, the PoC consists of a set of GStreamer elements that are …
