Liquidsoap freezes when using gstreamer

[xorinzor]

I seem to be unable to produce a video stream using gstreamer, it will load my script and then just do nothing, when pressing ctrl+c it says that it's waiting for the remaining processes to terminate, but that never happens.

Liquidsoap ./configure compilation output:

I'm using this script:

%include "config.liq"

set("log.file.path",                log_file_path_wrapper)

set("frame.video.width", stream_video_width)
set("frame.video.height", stream_video_height)
set("frame.video.samplerate", stream_video_framerate)

video_base = single("../images/novideosignal.avi")
clock.assign_new(sync=false, [video_base])
video_base = mksafe(video_base)

#input from the shoutzor script
live = input.harbor(stream_input_mount, port=stream_input_port, password=stream_input_password)

output = fallback(track_sensitive=false, [live, video_base])

logo_overlay = video.add_image(
       width=stream_video_logo_width, height=stream_video_logo_height,
       x=5, y=5,
       file=stream_video_logo,
       drop_audio(output))
output = mux_video(video=logo_overlay, drop_video(output))

#stream output to the public
output.icecast(

  %gstreamer(audio="vorbisenc",

  id="shoutzorOutput",
  icy_metadata="false",

  output)

This is the console output:

Hi! There's been extensive work done on gstreamer. Let me know if you're able to test on the latest code or need help doing it.

[xorinzor]

Glad to hear so, I don't think I'll be able to test it anytime soon though as I've not been into programming for quite a while now.

Ok, thanks. I'm gonna close this one, then. We're working on a similar issue with another user, hopefully that will take care of it. Thks for your interest in liquidsoap!
