Cloud Disk Player Helper is a video player helper extension for cloud disk providers. Currently, it supports 360Cloud (yunpan.cn) and BaiduCloud. This free Chrome extension allows you to playback non-mp4 (webm) video files, such as avi, mkv, and rmvb files, online in 360Cloud web pages.

One of the key features of this extension is that it relies on the "VXG Media Player" Chrome app for online playback. However, if you prefer not to install the app, you can still use basic functions like copying transcoded or original video links to other media players.

If you encounter any bugs while using Cloud Disk Player Helper, you can create a new issue on the GitHub issue page for prompt assistance.

Overall, Cloud Disk Player Helper is a useful tool for playing various video formats directly from your cloud disk provider's web pages.
