Description of your issue, suggested solution and other information

If youtube-dl downloads a file from the Mediathek (extractor/ard.py), it creates a so-called non-fragmented mp4 file, which cannot be played unless it is fully downloaded.

it'd be better if youtube-dl could repack the file creating fragmented mp4. Please see https://stackoverflow.com/questions/8616855/how-to-output-fragmented-mp4-with-ffmpeg for information on how this can be achieved using ffmpeg.

Of course, though they are often only valid for a few days: http://www.ardmediathek.de/tv/Tatort/Vorschau-auf-Tatort-Land-in-dieser-Zei/Das-Erste/Video?bcastId=602916&documentId=39711304 This is also just a short film. If you need a longer one, try this: http://www.ardmediathek.de/tv/Tatort/Hinter-dem-Spiegel/Das-Erste/Video?bcastId=602916&documentId=40609022

which cannot be played unless it is fully downloaded

Try this:

youtube-dl -v "http://www.ardmediathek.de/tv/Tatort/Hinter-dem-Spiegel/Das-Erste/Video?bcastId=602916&documentId=40609022" --hls-use-mpegts

This seems to work, indeed. Is there a way to make this default for a site?

[yan12125]

Site-specific options is still on its way: #8901. --hls-use-mpegts brings no harm unless you're using quite old video players. You may want to just put it in global configuration files.

Closing as the request feature is already implemented.

Thanks, already done!
