Remarks

yt-dlp extracted information about the currently airing programme, while yt-dlp-rajiko extracted information about the station. The latter is the correct way to go about it, in my opinion.

If, for example, you're recording a full 2 hours of the station, the airing programme may change multiple times during that two hours - but yt-dlp will give you the info as if it were just that same first programme for the whole two hours.

Remarks
  • yt-dlp's IDs are not unique between stations. If I download two programmes that aired at the same time, on two different stations, they will both have the same ID.
  • yt-dlp's extractor only fetches formats that are delivered as-live, not as on-demand. This means it's impossible for the download to go any faster than real time - a 30m show would take 30m to download, and so on. It's also why its title includes the time you started the download.
  • yt-dlp's extractor seems to be mistakenly compensating for the Japanese time zone offset, making its timestamps off by 9 hours.
