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:

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?

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.
