Media is considered to be blocked when all streams that belong to
that media are blocked.
This patch solves the problem of inconsistent updates of
priv->blocked that are not synchronized with the media state.
GstRTSPMediaPrivate *priv = media->priv;
GST_DEBUG ("media %p unblocking linked streams", media);
+ /* media is not blocked any longer, as it contains active streams,
+ * streams that are complete */
+ priv->blocked = FALSE;
g_ptr_array_foreach (priv->streams, (GFunc) stream_unblock, media);
}
