Prevent or recover from GST_STATE_CHANGE_FAILURE

[Erasmo Alonso Iglesias]

Hello,

The ARAS radio automation system uses two GStreamer playbin elements in order to play media continuously. Every time a new file has to be played, state is changed from GST_STATE_READY to GST_STATE_PLAYING.

Function gst_element_set_state is used to set state GST_STATE_PLAYING from state GST_STATE_READY. It usually returns GST_STATE_CHANGE_SUCCESS and everything works fine. However, in some systems after a number of played files it returns GST_STATE_CHANGE_FAILURE, and after that it seems not possible to perform more state transitions without getting a GST_STATE_CHANGE_FAILURE again.

Anybody knows how to prevent this condition or recover from it?

Best regards and thank you in advance,
Erasmo
