flowdownloader's Issues

Can we generalize it to suit other players?

I am getting the following error when I try to download encrypted videos from players other than flowplayer (link):

flowdownloader -k "MzliZDRmNmRlOTg4ZDliZA==" -u "https://video.dious.cc/20200724/GmYb4Mmm/index.m3u8" -debug

But it's downloading when AES key is empty. Can we generalize the flowdownloader to support more players?

Downloaded file won't play

After It downloaded the file, it is still unplayable with VLC. It detected the key and downloaded and decyrpted the file. But doesn;t work still.

Can we pass on all the files locally?

In my case, the primary and secondary index files and also the ts files are behind an authentication system that doesn't allow accessing the files for the second time. I have copied the primary and secondary m3u8 files by copying them from the Chrome cache. I have also downloaded the key. Is there a way to pass all the files to your command locally?
