Thinkphp video upload problems ~ Urgent

Thinkphp video upload problems ~ I am anxious to set the upload size for the server to 500 MB, which can also be used to upload such a large video. the format is the same as mp4, but why can I only play videos up to 20 MB during webpage playback, the excess is either loading all the time, or only sound, no image display. what is the problem? Firefox used in the browser has also been tried. The same is true for others. Is there a problem with my server settings or is there a problem ?? The video tag is used.

If you have uploaded a large file or not, it may cause playback failure. you can find a large file and try playing it directly.

Is it yours ?? Yes ???

Use FTP to upload a large video for playing. if this proves that your Upload program has no problem
If you cannot play the video or the video has a problem, check for other problems.

It is okay to play the source file directly after the upload. you cannot open it on the webpage. I can convert the MP4 format to the swf format today, but the video is blurred, only about m is needed after a multi-g conversion ~~

Should the source file format for playback be unsupported?

Try playing with player

I am not very clear about it, but thank you ~~ Try more
