videojs play m3u8 problem in win7 ie

When I was making a video last year, I sliced ​​the video into m3u8 format, and found that when win7 ie played m3u8 video, it could not be played. I don’t know the difference between win7 and win10 ie, but this really troubled me for a long time. Tudou also cannot play sliced ​​video normally under win ie, so the final solution is to play mp4 video when win7 ie is detected, or you can use flash.
