Hah, I think I accidentally figured out why everyone on BBC News looks so red for me. For some reason, my TV provider (#Tele2) specify BT.2020 colour space in the video metadata, while it's actually encoded in BT.709.
#FFmpeg came to the rescue on a test clip:
ffmpeg -i input.ts -codec copy -bsf:v h264_metadata=colour_primaries=1:transfer_characteristics=1:matrix_coefficients=1 output.ts
In the metadata there's an original network ID set to "Astra Satellite Network 19,2’E", wonder whether the stream comes with broken colourspace from there, or if it's #Tele2 that's messing things up.
A very long shot, but if anyone could make a short clip from "BBC News Europe" (SID 5001) on 11229 V, would really appreciate it ^v^
Haa, at least from this page, looks like it's in BT.2020 even there: https://www.digitalbitrate.com/dtv.php?mux=11229&pid=5001&live=61&sec=0&lang=en
@forst This was a very interesting problem thanks for sharing. You're right, it would be nice for technical users outside of an organization to sort of provide QA tickets/interface directly with some actual engineers. If you're a big enough "customer" you can get these tickets escalated.
I'm sure companies try to buffer those connections due to liabilities, social engineering, etc.
