Yes, it works for me on low stream only. I ignore display in CMD window
and the stream is continuous and lasts long.

I resize ffplay window and it looks good to me.

I use streamlink to watch BBC low because streamlink starts the stream instantly
while my shity script takes 3 seconds or so to show the stream.

Streamlink gives you HRTV low in a player continuously, remarkable achievement.

High stream is luxury and if I cannot get it I am sort of a shy to ask beardypig to get it for me.

There is more technical talk on streamlink and livestreamer threads on github,
while on this forum it is more broad and wide.

You may sound just stupid here and you are just fine here, this forum is superb
for both knowledge and non-knowledge.
