I guess the dashmpd urls timeout after a while.  Here is the current one for
that live stream:

http://manifest.googlevideo.com/api/manifest/dash/ip/216.228.112.21/fexp/9405988%2C9410705%2C9416126%2C9416891%2C9419452%2C9422596%2C9426198%2C9428398%2C9431012%2C9431881%2C9432055%2C9433096%2C9433221%2C9433946%2C9435526%2C9435693%2C9435876%2C9436607%2C9436636%2C9436804%2C9436824%2C9437066%2C9437226%2C9437282%2C9437552%2C9437742%2C9438662%2C9439160%2C9439260%2C9439482%2C9439652%2C9439944%2C9440009%2C9440376%2C9440738/sparams/as%2Cgcr%2Chfr%2Cid%2Cip%2Cipbits%2Citag%2Cplaylist_type%2Csource%2Cexpire/gcr/us/upn/seYXhS8AOv4/source/yt_live_broadcast/key/yt6/playlist_type/DVR/signature/0A26DCD10BCFFF4D82EBA7F13DB1D5159552FF98.C16E6E0673DBDCB6001016554FC1940AD9A48792/hfr/1/ipbits/0/sver/3/id/njCDZWTI-xg.54/as/fmp4_audio_clear%2Cfmp4_sd_hd_clear/expire/1467848496/itag/0

If that no longer works when you try it, you can obtain the current data for
that video by examining the output of:

$ curl www.youtube.com/get_video_info?video_id=njCDZWTI-xg

extract the dashmpd argument, and url decode the string.  Then, just use
gst-play-1.0 <that URL> and it should attempt to play.

I would be happy to add the debug output you asked for, but it would probably
be easier if you just tried the above to see if it works for you.

I attached my hacks to gstmpdparser.c in case they are useful.

Yes, it is a live stream.  It seems to have been detected as live (dynamic).

Thanks.
