You know Radio France is available as 280kbps HLS...

the full bouquets? 280k effective?
I don't have the means to verify this, but your comments surprise me a little... (I've also come across some lousy m3u8s in terms of compression, etc., but never the resolution you're referring to) if it could be verified, that would be nice
;-)
(on the other hand we even know that a general policy of the "round house" is going towards the worst quality side by trying to impose with delay the dab+ (88k max) and an approach via generalist app in m3u8 lousy but which is "sufficient for 96% of the contents")

I am pretty sure I told you a long time ago. The catch is it is available through the Radio France LMS plugin.

Thanks...
indeed, you told me about it...
I don't have LMS...
but what surprises me is that even after talking to engineers/managers* at their company, no one pointed out this resolution as being available.
I'm not a technician... but if there are ways to control actual speeds, I'm interested...
But hey, I might have to look into LMS... but just for my radio use...

(*They too are sorry for this lamentable evolution with its pathetic marketing of "digital quality" (massively compressed))
