Description of your issue, suggested solution and other information

My last successful download with youtube-dl from spiegel.tv was on 2018-05-23. I realized a change. It was possible to download the video with a single invocation of youtube-dl:

youtube-dl --output 'SPIEGEL.TV - Verkehrsrisiko Rentner.mp4' --format azure-http-1500 --ffmpeg-location /usr/local/opt/ffmpeg-static `http://www.spiegel.tv/videos/149746-verkehrsrisiko-rentner

Beforehand I had to download video and audio stream separately and multiplex with ffmpeg, for example:

youtube-dl --output '30 Jahre Spiegel TV.mpa' --format azure-hls-138  --ffmpeg-location /usr/local/opt/ffmpeg-static http://www.spiegel.tv/videos/1528233-30-jahre-spiegel-tv-nah-dran-investigativ-authentisch
youtube-dl --output '30 Jahre Spiegel TV.mpv' --format azure-hls-1676 --ffmpeg-location /usr/local/opt/ffmpeg-static http://www.spiegel.tv/videos/1528233-30-jahre-spiegel-tv-nah-dran-investigativ-authentisch
ffmpeg -i '30 Jahre Spiegel TV.mpa' -i '30 Jahre Spiegel TV.mpv' -c copy '30 Jahre Spiegel TV.mp4'
