我正在尝试对要在HTML5视频元素中使用的视频进行编码。但是,它在我的PC上的IE Edge中不起作用。但是,它的确适用于:

  • Chrome,Firefox
  • 我的Android智能手机(Chrome,Firefox)

我有两个非常相似的文件(一个是大钱兔子预告片,第二个是我试图编码的视频):

图片:Encoding-Settings

正如你所看到的那样" 1.mp4"正确播放," 3.mp4"不是。

您可以在此处下载文件:3.mp4 - 将3.mp4更改为1.mp4以获取其他视频。

我的ffmpeg-commandline是这样的:

ffmpeg.exe -i in.mp4 -c:v libx264 -movflags faststart -profile:v baseline -level 3.1 -preset slower -crf 30 -c:a copy 3.mp4

但是,我也尝试过:

ffmpeg.exe -i in.mp4 -c:v libx264 -profile:v baseline -level 3.1 -preset slower -crf 30 -c:a copy 3.mp4

ffmpeg.exe -i in.mp4 -c:v libx264 -preset slower -crf 30 -c:a copy 3.mp4

结果的ffprobe输出(对于有效的文件):

任何人都可以指出我正确的方向是两个视频之间的区别是什么以及如何修复我的ffmpeg命令行来播放" 3.mp4"在IE Edge?

答案 0 :(得分:0)

3.mp4在Firefox中不起作用,但如果我对音频进行重新编码,则可以正常工作:

ffmpeg -i 3.mp4 -c:v copy -movflags +faststart 3new.mp4
