I double-checked this. The svtplay-dl binary offered as a download
(version 4.10) seems to be broken. It has a date parsing error which
seems to be fixed in the git version (and the fix should be in 4.10, so
d'uh).

With the git version, I get this result:

[barsnick at goodtimes svtplay-dl]$ ./svtplay-dl --live --only-video -g https://www.svtplay.se/kanaler/svt1
https://svt1-d.akamaized.net/se/svt1/manifest.mpd?defaultSubLang=1

And ffmpeg can handle that given URL just fine.

(Funny thing: Since SVT seems to have separate substream manifests for
video and audio now, svtplay-dl apparently currently cannot give you
both those URLs with "-g", you get only a pure video URL. With the
"--only-video" only "--only-audio" option as shown above, I get the
overall manifest which includes three stream qualities. If you throw
that at ffmpeg, it will select the best stream qualities by itself, or
you can just do "-map 0:M -map 0:N".)

I agree, I do the same once in a while. :-)

I do this not with a start time, but as an "at" job.
