I’m using yle-dl from the HEAD and ffmpeg & ffprobe built from git. For the three URLs listed above, I could only get subtitles to download for the last one (with --debug) until I tried playing it in the web player, after which they were no longer downloaded for that one either. Aargh :)

Here’s --debug output for the first download (before opening in webplayer), resulting in subtitles being downloaded.

Here’s --debug output for the latter download (after opening in webplayer), resulting in subtitles not being downloaded.
