What did you do?

I have a multi period stream with Close caption (only 1 track for CC)

What did you expect to happen?
I was expecting the if (streams.has(key)) { to find my stream all the time in my multi period stream

What actually happened?

but in fact when debugging i was able to see that the key was not found in streams
My output stream has no CC information. so it's null meaning the key is like that
[false,768,30,"avc","video/mp4",null,[],null,1400000]

But the key in the stream is like that
[false,768,30,"avc","video/mp4",null,[],[],1400000]

look like the outputStream is not with the same structure as the stream, outputStream can be null and stream can be empty array

look the clone stream is not doing it correctly compare to the origin stream

Are you planning send a PR to fix it?

I'm sorry i have no time now to work on it
Sorry guys
