"Can't support the subtitle"

[emilhja]

Hi,

Hi, new user here. I much appreciate your work! But I have an issue that I can only download without subtitles.

I have Windows 10, python 3.1, ffmpeg version 5.
wget is working but is horribly slow.

This generate a working video-file without subtitles.
yle-dl https://arenan.yle.fi/1-50952507 -o video1.mkv

but with following error:

Any recommendations?

Or, since wget is generating a *.srt-file. Is it possible to only download the srt with wget?

I'm quite sure I've not done any changes but my first videos doesn't contain any subtitles.

But now my latest generated videos contain subtitles!

It still says the following, but maybe not an issue if I can see subtitles in the video?

br,

The situation with subtitles is quite confusing currently, sorry about that. Yle-dl currently always prints the two warnings "Can't support the subtitle" and "Dropping X duplicated subtitle events" but the subtitles should still get downloaded.

If you still happen to have the video3.mkv file from your first message, can you verify that it really doesn't contain subtitles? Run the command ffprobe video3.mkv. It outputs information about the content of the video file. The output should contain a section about subtitles, something like this:

  Stream #0:2(fi): Subtitle: subrip (default)
    Metadata:
      VARIANT_BITRATE : 3757872
      COMMENT         : käännöstekstitys
      ENCODER         : Lavc58.134.100 srt
      DURATION        : 00:04:24.779000000

If you see this section in the output, the subtiles were download. In that case, make sure that the correct subtitle language is selected in your video player. If you don't see the subtitles section, then it's a bug in yle-dl (or Areena).

Seen a lot of them subtitle complaints.

Guessed it has to do with multi-language subtitles?
yellow in my win setup, ffmpeg?? 4.3.1 uses red too, yle-dl python doesnt??
chaged video title too when svm if available?

yle also had some strange way cookie? for deciding on wiever language, browser fin/sv arena?

hmm.. long time ago "dutch" (as subtit?) was a robot audio-speaking the text??

I have improved the support for subtitles on the master branch. There should not be warnings about subtitles on most cases anymore.

More detailed explanation: I have switched to using MPEG-DASH streams instead of HLS when possible, because ffmpeg has a better support for subtitles in DASH streams.

Low resolution streams may still result in warnings concerning subtitles, because they seem to be available only as HLS format. Even then the subtitles should work despite the warnings.
