Frequently Asked Questions

How does this work, any limitations ?

File reading and calculations are done in your browser. So there's no interaction with any server. There's only one limitation. Your file should be under 1MB, generally initialization files are 2-3 KB, so you should be fine. However, if you come across anything different, please create an issue.

What does this mean Failed to extract PSSH from your file ?

It's possible that you've passed an invalid file. Make sure you use the initialization file. If this error still occurs, feel free to create an issue.

Why ?

Why not ?

TODO

  • Add tests
