Here's the deed (from @dromer)

Script (simplified):

s = playlist("<some path>")

output.gstreamer.audio_video(
    video_pipeline=
        "videoconvert ! gdkpixbufoverlay location=/media/logo.png offset-x=768 offset-y=20 ! x264enc bitrate=2000 ! video/x-h264,profile=baseline ! queue ! mux.",
    audio_pipeline=
        "audioconvert ! voaacenc bitrate=44100 ! queue ! mux.",
    pipeline=
        "flvmux name=mux ! rtmpsink location=\"rtmp://10.0.0.105:1935/live/show live=1\"",
    s)

Btw that GST_STATE_CHANGE_PLAYING_TO_PAUSED in thread 13 is me messing on the telnet interface. Which doesn't do anything except set these state changes (stream still dead)

@dromer This is the same backtrace that I posted on the gstreamer mailing list: http://gstreamer-devel.966125.n4.nabble.com/gst-element-set-state-deadlock-td4682492.html#a4688136
In my experience, upgrading to 1.14.2 (debian testing) fixed the issue. Could you confirm?

I'll remove the debian packages and re-make install my 1.14.2 build :)

Hmm, I'm unable to get webm decoding to work .. will come back to you when I have a working setup with 1.14.2 ..

Ok I made a playlist with videos my setup can play and I can confirm that 6 hrs later it is still running, no memory or stability issues whatsoever with 1.14.2.
Now I just need to fix webm support :P

[Edit: nevermind, I was missing vorbis support, works like a charm with 1.14.2!]

You mean it works with older gstreamer now too?

Imo it would be nice if we can get this working on debian stable.
