1. 运行环境1. Requirements
| 要求Requirement | |
|---|---|
| 系统OS | Windows 10 / 11（64 位）Windows 10 / 11, 64-bit |
| 播放核心Playback engine | 随应用自带 LibVLC，无需另装解码包或 VLCLibVLC ships with the app — no codec pack, no separate VLC install |
| 蓝光Blu-ray | 自带 libaacs.dll；keydb.cfg 自动解压到 %APPDATA%\aacs\Bundled libaacs.dll; keydb.cfg is extracted to %APPDATA%\aacs\ automatically |
| 设置文件Settings file | %LOCALAPPDATA%\CoolleDVDFreePlayer\Settings.json |
2. 支持的格式2. Supported formats
视频Video
应用内置的格式白名单一共 156 种扩展名。用得最多的这些：
The built-in allow-list covers 156 extensions. The ones used most:
mp4 m4v mkv avi mov webm flv wmv asf divx mpg mpeg ts m2ts mts vob iso 3gp rm rmvb ogv dv
音频Audio
mp3 aac m4a flac wav ogg wma ape ac3 dts opus mka
字幕Subtitles
srt ass ssa sub idx smi vtt ttml dfxp
列表以外的文件仍可尝试：在打开对话框里把过滤器切到 All Formats (*.*)。能不能放最终取决于 LibVLC 是否支持该编码。
Anything outside the list is still worth a try: switch the dialog filter to All Formats (*.*). Whether it plays depends on LibVLC supporting the codec.

4. 还有问题4. Still stuck
打开 About 页面，用 Send Feedback 直接告诉我们：你在做什么、文件是什么格式、期望什么结果。带上版本号（关于页第一行）能省一半来回。
Open About and use Send Feedback: say what you were doing, the container of the file, and what you expected. Including the version number from the top of the About page saves a round trip.
