A hands-on tutorial teaching how to use FFmpeg's libav libraries for media processing, from basics to transcoding and transmuxing.
FFmpeg libav tutorial is an educational resource that teaches developers how to use FFmpeg's underlying libraries (libav) for multimedia processing. It starts with fundamental concepts of video and audio, then provides practical examples for transcoding, transmuxing, and building media applications. The tutorial solves the problem of learning low-level media manipulation by offering clear, code-focused lessons.
Developers and engineers working with multimedia who need to programmatically process video and audio, such as those building media servers, video editors, or streaming applications. It's particularly useful for those who want to move beyond FFmpeg command-line usage to library integration.
Unlike generic FFmpeg documentation, this tutorial provides a structured, hands-on path from basics to advanced topics with working C code examples. It bridges the gap between theory and practice, making libav accessible to developers who need fine-grained control over media processing.

Explains core concepts like codecs, containers, and timing from the ground up, with clear diagrams and calculations for video storage needs, making theoretical knowledge accessible.
Provides step-by-step C code for decoding, encoding, transcoding, and remuxing, including practical tasks like saving frames as PGM images and creating DASH manifests.
Follows a 'learn by doing' approach from basics to advanced topics like adaptive streaming, with chapters sequentially building on concepts such as PTS synchronization and packet handling.
Covers practical scenarios like transcoding H264 to H265, remuxing to fragmented MP4 for streaming, and includes configuration tips for codec settings like x265 params.
Examples are primarily in C, which may deter developers unfamiliar with manual memory management or those preferring higher-level languages, despite brief mentions of bindings.
Requires Docker or specific environment setup to run examples, as noted in the README's requirements, adding overhead for beginners or those with system constraints.
In the transcoding chapter, the author admits to warnings and the need to enforce settings like 'force-cfr', indicating subtle bugs and complexities that can hinder smooth implementation.
Focuses heavily on low-level libav API usage without addressing integration with modern frameworks or best practices for scalable, production-ready media pipelines.
