File size limitations - MP4

[JohnRubado]

Hello! I am attempting to share mp4 files that can be anywhere from 10-80 MB. Some files work, while others fail with Permission Denied and a Share too large warning message.

What are the file size limits? and are the file size limits specific to anything like the browser or file type?

Also, if there is documentation that has this info please let me know, I can't seem to find it.

Thank you

Hi @JohnRubado! The specification doesn’t enforce any limitations but browsers themselves might (which sounds like what you hit). Which browser and/or OS is this on?

For example, Blink rejects shares with more than 10 files, or where the total of the file sizes exceeds 50MB.

I think we could give some examples as part of #217, but wouldn't want to lock anything in. These would change over time.

It does seem like it is a browser restriction. I am getting the same error on both Android 12 Chrome 96, Windows Chrome 96, and Windows Edge.

We want to support sharing video files to tiktok, instagram, and youtube and we meet all their file size restrictions but we are blocked by this size restriction on the browser unfortunately

As the above doesn't affect the spec, I'm going ahead and closing this. If this is still an issue, it might be good to raise over on blink-dev maybe?
