Description

I've successfully downloaded a couple of videos from wdrmaus.de but others don't seem to work. It looks like they are using different video players for different (older?) content.

This video works:
https://www.wdrmaus.de/filme/sachgeschichten/ice4_teil1.php5

Examples of videos that don't work:

• https://www.wdrmaus.de/filme/sachgeschichten/dampflok.php5
• https://www.wdrmaus.de/filme/sachgeschichten/ice_wartung.php5
• https://www.wdrmaus.de/filme/sachgeschichten/feuerwehrloeschzug.php5

Looking at apage that doesn't work, it points to an assetjsonp file. Thhis assetjsonp contains the actual videoURL that you can directly download with wget.

Try the nightly build that includes PR #30556. Actually, use the nightly build anyway. See #30839. Probable duplicate of #30484.

[ChristianKuehnel]

I did not find any information related to a "nightly build", however it works using the current master branch 00ef748 --> closing the issue. Thx for the fast reply!

I wasn't aware that there weren't any releases for such a long time...

#30839:

Known issues, fixed in git master code, or update/install from the nightly release repo:

OK, so I've hit another video from the same site that doesn't work with the nightly release:
