ffmpeg命令转换后的视频未在windows上播放

ffmpeg

ffmpeg命令转换后的视频未在windows上播放,ffmpeg,Ffmpeg,我被困在一个非常奇怪和复杂的问题上，希望如果有人知道解决方案： 我在服务器上使用ffmpeg命令转换用户上传的视频，效果也很好。今天我发现，如果一个视频是由一个网络摄像头从windows录制的，那么它在linux和windows上都能播放得很好，就像用户从linux通过网络摄像头创建视频一样，它只在linux（任何浏览器）上播放。在窗口上，当音频正常工作时，屏幕上显示加载图标或黑屏 我正在使用以下编解码器： ['-strict', '-2', '-preset slow', '-maxrate

我被困在一个非常奇怪和复杂的问题上，希望如果有人知道解决方案：

我在服务器上使用ffmpeg命令转换用户上传的视频，效果也很好。今天我发现，如果一个视频是由一个网络摄像头从windows录制的，那么它在linux和windows上都能播放得很好，就像用户从linux通过网络摄像头创建视频一样，它只在linux（任何浏览器）上播放。在窗口上，当音频正常工作时，屏幕上显示加载图标或黑屏

我正在使用以下编解码器：

['-strict', '-2', '-preset slow', '-maxrate 500k', '-bufsize 1000k', vfOption, '-threads 0', '-ab 64k', '-movflags faststart','-vf scale=-1:480', '-metadata:s:v:0 rotate=0', '-vcodec libx264']
我在linux上工作，在我的网站上使用html5播放器。我正在转换mp4格式的视频
