* @GST_MSE_SRC_READY_STATE_HAVE_METADATA: The duration is available and video

* @GST_MSE_SRC_READY_STATE_HAVE_FUTURE_DATA: There is data for the current

* @GST_MSE_SRC_READY_STATE_HAVE_ENOUGH_DATA: Either there is enough data to
* play the stream through at the current playback and input rate or the input
* buffer is full.

* Describes how much information a #GstMseSrc has about the media it is playing
