Anyone know how the 4K feature detection works? For example, can a certain user agent be spoofed to enable the higher-res version? I ask because I use youtube-dl to watch iPlayer shows and it only grabs standard HD versions. If anyone else UK based has figured this out I'd love to learn how.

    The 2.2GB download is a 1280x720 50FPS MP4, definitely a long way from 4K HDR. Testing with the --list formats option does not identify any higher resolution.

      That is what I thought, I got my thoughts tangled up, the one I downloaded was 1.1Gb, which seems standard for an hour of 720p. Mind you there is the option for other Attenborugh fans to download the audio only track
ihalip 9y ago
The version of iPlayer which I worked with had a setting to enable "beta features", this includes 4K UHD videos. So you'd probably need to spoof a TV/STB UA and set a cookie.

Wondering this also. Could be that the modes we see are all that's currently available. Looks like the 4K streams won't be available for another 24+ hours: > The BBC plans to release the special edition of Blue Planet II immediately after the final episode is broadcast on BBC One on Sunday.

Isn't that the default, with no other arguments?

Is get-iplayer still used? I suspect it'll need an enhancement from youtube-dl in your case.

I did look at all the file options, and there was a 2.2Gb download, but the standard download was about 130Mb.

  The 2.2GB download is a 1280x720 50FPS MP4, definitely a long way from 4K HDR. Testing with the --list formats option does not identify any higher resolution.

    That is what I thought, I got my thoughts tangled up, the one I downloaded was 1.1Gb, which seems standard for an hour of 720p. Mind you there is the option for other Attenborugh fans to download the audio only track

The version of iPlayer which I worked with had a setting to enable "beta features", this includes 4K UHD videos. So you'd probably need to spoof a TV/STB UA and set a cookie.

Wondering this also. Could be that the modes we see are all that's currently available. Looks like the 4K streams won't be available for another 24+ hours: > The BBC plans to release the special edition of Blue Planet II immediately after the final episode is broadcast on BBC One on Sunday.
