You would need to stitch blocks on a server

I'm not sending the video server side - it is all done in the browser.

he might be referring to files over 2GB?

Apologies - let me try and be more clear. The user loads a local movie into the browser, and the browser then processes locally with ffmpeg. The movie started on the client and stays there. If it is less than 2GB then no problems. If it is larger then it hits this limitation. (I am taking the results from ffmpeg and sending those server side, but those results are always << 2GB and therefore no issues).

Maybe the suggestion is to only load < 2GB into ffmpeg in the browser? I could see how that would work for the 1st chunk. But the 2nd one and beyond would not be valid.

I found this https://github.com/ffmpegwasm/ffmpeg.wasm#what-is-the-maximu...

the inputfile needs a uint8 array, which i tried converting file to uint8 but that gives a file format error and doesnt process the ffmpeg command

I looked at the ffmpeg inputfile and its a uint8, converted a file object to uint8 did not work too - gives a file format error!

any updates on this?
