Failure to download RTMP stream from Youtube

[zwerfvogel]

My video is detected as having an RTMP stream, but it is not downloaded correctly, despite rtmpdump 2.4 being installed.

It seems that youtube-dl is wrongly calling rtmpdump
This part is from rtmpdump:

ERROR: You must specify a playpath (--playpath) or url (-r "rtmp://host[:port]/playpath") containing a playpath

[zwerfvogel]

Yes, but I do not think it is called incorrectly -- I ran rtmpdump separately, ensuring that the syntax was correct. After looking at similar issues related to RTMP, it seems that the real problem is a generic url returned from Youtube.

[naoliv]

It's missing the video URL after rtmpdump --verbose -r rtmpe://v10.nonxt2.c.youtube.com/videoplayback[SOMETHINGHERE]?

[zwerfvogel]

Yes, something like that -- have a look at #2908 and #343 but it is not clear what the status of those bugs is.

[naoliv]

Looking at #343 it seems that it's very difficult to find the proper stream URL.
It's still open.
