  "github_readme_excerpt": "# H26Forge\n\nH26Forge is domain-specific infrastructure for analyzing, generating, and manipulating syntactically correct but semantically spec-non-compliant H.264 video files.\n\nH26Forge has three key features:\n1. Given an Annex B H.264 file, randomly mutate the syntax elements.\n2. Given an Annex B H.264 file and a Python script, programmatically modify the syntax elements.\n3. Generate Annex B H.264 with random syntax elements, which can be written to files or streamed over RTP\n\nThis tool and its findings are described in the [H26Forge paper](https://wrv.github.io/h26forge.pdf).\n\n## Motivation\n\nSee [MOTIVATION.md](docs/MOTIVATION.md) to see how a H26Forge simplifies a previously manual PoC generation process.\n\n## Release\n\nYou can downloaded the latest build on the [releases](https://github.com/h26forge/h26forge/releases) page.\n\n## Building\n\nAn up-to-date version of Rust is required to build H26Forge. Be sure to call `rustup update`.\n\nPython 3 is required for editing videos.\n\n**Linux/Mac**\n```\n./make.sh\n```\n\n**Windows**\n```\n./make.bat\n```\n\nThese scripts just call `cargo build --release` and copy the binary to the top level directory.\n\n## Quickstart\n\nTo generate a video with the default configuration, run:\n```\n./h26forge generate -o out.264\n```\n\nTo use a custom randomness range, modify (or copy and create a new file) the syntax element range in [config/default.json](config/default.json) and run:\n```\n./h26forge generate -o out.264 -c config/default.json\n```\n\nA [simple script](scripts/gen_100_videos.sh) is included to generate a batch of 100 videos to a temporary folder. You can run it via:\n```\n./scripts/gen_100_videos.sh\n```\nThe videos will be output to `tmp/`.\n\n\n[Another script](scripts/gen_100_chrome_videos.sh) is included to generate 100 videos using [config/chrome.json](config/chrome.json).\n```\n./scripts/gen_100_chrome_videos.sh\n```\nYou can open the videos in a browser by opening `tmp/\u003coutput\u003e/play_videos.html`.\n\n\nSee [GETTINGSTARTED.md](docs/GETTINGSTARTED.md) for ",
