我正在尝试播放 WebM VP9 视频文件。媒体播放器说该视频无法播放。
这意味着，我无法跳转到不同的时间或来回跳过几秒钟。每次播放视频时，我都必须从头开始。我可以暂停播放并继续。但如果视频停止，我必须从头开始观看。
有没有类似的开源工具FFmpeg可以用来让视频可搜索？怎么做？
到目前为止，我已经尝试ts-ebml过 Node.js（建议在这里使用 ffmpeg 查找 opus webm 音频的正确参数是什么？)：
Linux
ts-ebml -s not_seekable.webm | cat > seekable.webm
视窗
ts-ebml -s not_seekable.webm | type > seekable.webm
它不适用于大于 2 GB 的文件。
Syntax error.

throw new ERR_FS_FILE_TOO_LARGE(size);

我已经分析了我所指的视频文件ffprobe：
D:\>ffprobe testvideo.webm
也许这些信息有帮助。这是控制台输出：
