muxing fragments from ismdownloader

[aischan]

Hello!

Today I recorded a stream using ismdownloaderavc like I do every time. However today it stopped responding after a period of time but still recorded what I wanted. I had to close ismdownloader before it could mux the files to MKV. So I am left with a manifest file with no extension and 2 folders full of the fragments of video and audio with no extensions. It was a live stream so I have no way of trying again. Is there any possible way to mux these files together so I have an mkv video as a result?

Any help would be greatly appreciated
