Greptile Overview

Greptile Summary

This PR upgrades FFmpeg from version 7.0.1 to 8.0.1 across the installation script and documentation.

Changes:

• Installation script: Updates FFMPEG_VERSION to 8.0.1 and adds nasm as a build dependency
• Documentation: Updates all references from "FFmpeg 7.0+" to "FFmpeg 8.0+" in user-facing docs

Purpose:
The upgrade to FFmpeg 8.0.1 brings the project to a newer major version of FFmpeg. The addition of nasm (Netwide Assembler) is required for optimized assembly code compilation in FFmpeg 8.x builds.

Compatibility:
The FFmpeg command-line interface and encoding options used in the codebase (h264_nvenc, libx264, libopenh264) remain stable across this version upgrade. No changes to the Python code are required as the project interacts with FFmpeg through subprocess calls using standard CLI arguments that are compatible with both versions.

Confidence Score: 5/5

• Safe to merge - straightforward version upgrade with consistent documentation updates
• This is a clean version upgrade that updates the FFmpeg version consistently across installation scripts and documentation. The changes are minimal, well-scoped, and don't modify any core logic. The addition of nasm as a dependency is appropriate for FFmpeg 8.x compilation. All FFmpeg CLI options used in the codebase remain compatible between versions 7.0.1 and 8.0.1.
• No files require special attention
