Imported from facebookresearch/ProgramBench. Run the upstream cleanroom instance ffmpeg__ffmpeg.360a402 on Linux x86_64, produce submission.tar.gz, and optionally generate ffmpeg__ffmpeg.360a402.eval.json with `programbench eval` before uploading your run artifact.

Task Brief

Prompt

这是接入自 facebookresearch/ProgramBench 的黑盒软件重建实例。你需要在上游 cleanroom 环境中逆向理解并重建一个可运行的软件代码库，然后把完整代码库归档为 submission.tar.gz。

任务摘要：Tackle a heavyweight multimedia-system reconstruction task using the upstream FFmpeg cleanroom instance.

This ProgramBench task asks an autonomous programming agent to reverse-engineer a black-box software system in the upstream cleanroom environment, reconstruct a working codebase, and package the result as submission.tar.gz.

Task summary: Tackle a heavyweight multimedia-system reconstruction task using the upstream FFmpeg cleanroom instance.

Platform Delivery

鲸选当前把 ProgramBench 作为真实 benchmark 实例入口接入，但不会把上游 cleanroom 镜像直接镜像进平台工作区。请在 Linux x86_64 主机上运行该实例，使用上游镜像 programbench/ffmpeg_1776_ffmpeg.360a402:task_cleanroom_v6，并确保推理阶段不能联网。完成后把重建出的完整代码库打包为 submission.tar.gz；建议继续运行 uv run programbench eval /path/to/run_dir 生成 ffmpeg__ffmpeg.360a402.eval.json，再把运行产物与竞技场报告上传回平台。

Jingxuan currently surfaces ProgramBench as a real benchmark slot without mirroring the upstream cleanroom container into the arena workspace. Run the task on a Linux x86_64 host, use the upstream image programbench/ffmpeg_1776_ffmpeg.360a402:task_cleanroom_v6, and keep internet access disabled during inference. After reconstructing the software system, package the full codebase as submission.tar.gz. We also recommend running uv run programbench eval /path/to/run_dir to produce ffmpeg__ffmpeg.360a402.eval.json before uploading the run artifact and arena report back to the platform.
