In the UK we're required to have a TV licence to watch iplayer content and presumably other BBC video material. I'd like to block video but allow other stuff through. Advice please.
Blocking iplayer is easy since it's a domain name and you need to sign-in anyway.
The regular website for live broadcasts, not sure how that'd be done because what if someone goes to YouTube and watches a BBC live broadcast there? So you will need to do some research for that one.
it's black or white, you can't block it for non paying users only, unless you know who they are.
I make some effort to identify domains that serve video from the BBC in order to apply DSCP tags for QoS. These are the domain suffixes in my list:
vs-cmaf-push-uk-live.akamaized.net
ve-dash-uk-live.akamaized.net
vod-dash-uk-live.akamaized.net
vs-dash-uk-live.akamaized.net
vs-hls-uk-live.akamaized.net
as-dash-uk-live.akamaized.net
bbcfmt.hs.llnwd.net
bbcfmt.s.llnwi.net
bidi.live.bbc.co.uk
live.bidi.net.uk
md.bbci.co.uk
open.live.bbc.co.uk
I doubt this list is comprehensive and obviously it will need to be kept up to date, but blocking these suffixes in dnsmasq would get you some of the way there at least.
Also bear in mind that blocking these will almost certainly interfere with video content in news articles etc. as it's all served from the same infrastructure.
I can leave a thumbs up under a post. Is it possible to add a thumbs down function? 
No. But since you're not the OP, maybe you can discuss what needs a thumbs down instead, and perhaps provide better information)?
It's more expansive than that: you're required to have a TV license if you watch any live TV by any means in addition to iplayer content.
So watching a live stream would count. And most of the streaming packages today have a live option. Netflix does. Amazon does. As does Youtube.
So blocking live streams is practically impossible. And policing whether or not someone views livestreams is equally impossible.
Then I suggest not blocking, and simply practice civil disobedience.
The yookay government is focused on catering to enemies and foreigners. You owe them nothing.
The bigger question would be, why do you think you are responsible for policing your users?
Don't get me wrong, "TV licenses" are quite common around the world, but mostly the responsibility lies with the prospective users, not the (internet-) service provider - and you get into murky waters regarding network neutrality and privacy laws very, very quickly.
So the more important question would be, did you talk to a lawyer about your plan?
I like your post.
I've solved the problem by blocking all bbc.co.uk. Still, it would have been handy to be able to use the free services like news, radio, weather, podcasts etc. I have found other sources of news coverage and weather. I'm working on the rest. Hey ho...
Yep, I'm sure, since they licence TVs (what?) in UK, they require some badge from those who wants to police others.
So are you going to block YouTube too?
