I'm writing a C# WPF application using GStreamer 0.10.35 (OSSBuild-vs2010 2012.06.15 with .NET4 C# bindings).
I'm using gnonlin and my pipeline contains two chains: one for audio and the other for video.
On my machine when I disconnect the headphones while playing the pipeline, the playback pauses for a second and continues playing. On another machine with a different sound card disconnecting the headphones causes the application to freeze. Some *idiot* wrote sound card drivers in such a way that the audio device becomes disabled when the headphones are disconnected.
When looking at GStreamer logs I can see the following warnings:
0:00:22.761000000 7120 0B3C2EF8 WARN waveformsink gstwaveformsink.c:507:gst_waveform_sink_write:<autoaudiosink1-actual-sink-waveform> gst_waveform_sink_write: Error preparing header => There is no driver installed on your system.
0:00:22.761000000 7120 0B3C2EF8 WARN waveformsink gstwaveformsink.c:514:gst_waveform_sink_write:<autoaudiosink1-actual-sink-waveform> gst_waveform_sink_write: Error writting buffer to the device => The wave header was not prepared. Use the Prepare function to prepare the header, and then try again.
What can I do in such situations? How to make the pipeline continue playback even if the headphones are disconnected?
