Hi please reopen this issue now I have which files cause this gstreamer error.
Gstreamer works fine for few hours but fails to reconnect if any issue happens
and feeds blank audio
Note: script is not fallback to emergency mp3 file and retries gstreamer source
every 3 seconds.
I have tried with following configurations,
liquidsoap 1.1.3, 1.1.6, 1.3.7, 1.4-dev
gstreamer=0.3.0 and dev
gst-launch-1.0 version 1.14.0
GStreamer 1.10.0
and
gst-launch-1.0 version 1.17.0
GStreamer 1.17.0 (GIT)
```
