摘要： 流式传输360$^\circ$视频用于虚拟现实需要大量的带宽。 为了优化这种传输，视频被分成“图块”并根据用户观看的内容选择性地分发给用户。 这种交互式方法使得评估质量和用户体验变得困难。 为了解决这个问题，本文介绍了py360tools，这是一个Python库，可以自动化客户端任务，如视频重建、图块选择和视口提取。 这有助于重现、模拟和分析 360$^\circ$视频流媒体会话。 显示英文摘要

摘要： Streaming 360$^\circ$ videos for virtual reality demands a lot of bandwidth. To optimize this transmission, videos are divided into "tiles" and selectively distributed to the user based on what they are looking at. This interactive approach makes it difficult to assess quality and user experience. To solve this, the paper presents py360tools, a Python library that automates client-side tasks like video reconstruction, tile selection, and viewport extraction. This facilitates the reproduction, simulation, and analysis of 360$^\circ$ video streaming sessions.
