Great things seem to be working OK now.

Is it possible to choose streams?

There are some logging nits on the mpds I've tested.

http logs per chunk

No trailing CRLF found in HTTP header.

https additionally logs

The TLS connection was non-properly terminated.

With a live stream plus -loglevel verbose there is "too much"

I don't know if this url will work outside the UK.

ffmpeg -loglevel verbose -i
