我尝试过QTIndexSwapper，但是它说索引位置正确.

I have tried QTIndexSwapper but it says the index is in the right position.

任何帮助表示赞赏.

推荐答案

看起来MOOV原子不在文件的开头. 我使用ffmpeg重新定位(没有其他编码)，然后进行二进制比较(使用 HexFiend )和快速测试似乎表明Safari会更快地播放视频

looks like the MOOV atom isn't at the beginning of the file. I used ffmpeg to just relocate that (no other encoding) and then a binary compare (using HexFiend) and a quick test seemed to show that Safari was playing the video sooner

./ffmpeg -i top.mp4 -codec copy -movflags faststart top-fs.mp4

(原因是，即使我清除了浏览器缓存，我也没有做诸如弹跳测试服务器或对时间计时太准确的事情)

(caveat being that even though I cleared browser cache I didn't do things like bounce my test server or time things too accurately)

FWIW我发现ffmpeg是一个很好的解决方案，尤其是对于背景视频，您需要

FWIW I find ffmpeg to be a good solution, and especially for background video you'll want to play around with parameters to optimize for your use-case
