Hi, i'm trying to play the following stream via gstreamer gst-launch-1.0 
souphttpsrc is-live=true 
location=https://d2e1asnsl7br7b.cloudfront.net/7782e205e72f43aeb4a48ec97f66ebbe/index_5.m3u8 
! hlsdemux ! decodebin ! videorate ! videoconvert ! ximagesink 
Unfortunately the stream is stopping after a few seconds. Afterwards the 
picture is updated in a very slow frequency (1 picture in 10 seconds, or 
slower). I set the debug level to 3 and see the following message before 
the stream is stopped. calculate_skew: backward timestamps at server or 
no buffer timestamps. Resync base PCR I notified the problem on my 
current arch linux installation, and also on a ubuntu machine. Other 
streams working fine. The problem seems also related to this stream. The 
stream is working in vlc fine. I'm new in gstreamer, so i don't have any 
ideas how to proceed. Are there extra special options, to fix this 
problem? Have anyone an idea, why the stream is stopping? Thanks in 
advance and best regards Marcel 0:00:22.821619516 42400 0x7f5d9000d760
