Reading files larger than what Chrome allows in MEMFS (>261MB)

Hi,

My goal is to use FFmpeg with a particular run command on files which are going to be very large (multiple gigabytes). It is required that it executes entirely on the client as no data is allowed to be transmitted back to the server. Correct me if I'm wrong but using FFmpeg with node will mean the data is transmitted to the server for processing. If that is the case then node won't be suitable. I know that modern browsers have limits on how large the file can be which it can read with FileReader. Does FFmpeg support buffered reads of the file?

Thanks,
Oliver
