About:
H264bitstream is a lightweight C library designed for parsing and generating H.264 video streams. It provides developers with low-level access to NAL units and sequence parameter sets, enabling direct manipulation of encoded video data. This tool is essential for applications requiring analysis, modification, or creation of H.264 elementary streams without a full decoding pipeline.

Key Features:

Low-level H.264 elementary stream parsing and writing
C library with no external dependencies
Access to NAL units, SPS, and PPS data
Supports both reading and writing operations

Use Cases:

Analyzing H.264 stream structure for debugging or compliance testing
Injecting or modifying NAL units in real-time streaming applications
Building custom H.264 stream generators or remuxers

Alternatives:

FFmpeg – FFmpeg is a comprehensive multimedia framework that includes H.264 parsing but is significantly larger and more complex.
OpenH264 – OpenH264 focuses on encoding/decoding rather than low-level bitstream parsing and manipulation.
