scuffle-h264
[!WARNING]
This crate is under active development and may not be stable.
A pure Rust implementation of the H.264 (header only) builder and parser.
This crate is designed to provide a simple and safe interface to build and parse H.264 headers.
See the changelog for a full release history.

Examples
Parsing
use std::io;
use bytes::Bytes;
use scuffle_h264::{AVCDecoderConfigurationRecord, Sps};
// A sample h264 bytestream to parse
// Parsing
let result = AVCDecoderConfigurationRecord::parse(&mut io::Cursor::new(bytes)).unwrap();
// Do something with it!
// You can also parse an Sps from the Sps struct:
let sps = Sps::parse_with_emulation_prevention(io::Cursor::new(&result.sps[0]));
For more examples, check out the tests in the source code for the parse function.
Building
use bytes::Bytes;
use scuffle_h264::{AVCDecoderConfigurationRecord, AvccExtendedConfig, Sps, SpsExtended};
let extended_config = AvccExtendedConfig {
chroma_format_idc: 1,
bit_depth_luma_minus8: 0,
bit_depth_chroma_minus8: 0,
sequence_parameter_set_ext: vec![SpsExtended {
chroma_format_idc: 1,
separate_color_plane_flag: false,
bit_depth_luma_minus8: 2,
bit_depth_chroma_minus8: 3,
qpprime_y_zero_transform_bypass_flag: false,
scaling_matrix: vec![],
}],
};
let config = AVCDecoderConfigurationRecord {
configuration_version: 1,
profile_indication: 100,
profile_compatibility: 0,
level_indication: 31,
length_size_minus_one: 3,
sps: vec![
Bytes::from_static(b"spsdata"),
],
pps: vec![Bytes::from_static(b"ppsdata")],
extended_config: Some(extended_config),
};
// Creating a buffer to store the built bytestream
let mut built = Vec::new();
// Building
config.build(&mut built).unwrap();
// Do something with it!
For more examples, check out the tests in the source code for the build function.
