static Glib::RefPtr<Gst::Message> | create (const Glib::RefPtr<Gst::Object>& src, int percent) |
Create a new buffering message. |
See create() for more details.
Gst::MessageBuffering::MessageBuffering | ( | GstMessage * | castitem | ) | [explicit] |
static Glib::RefPtr<Gst::Message> Gst::MessageBuffering::create | ( | const Glib::RefPtr<Gst::Object>& | src, | |
int | percent | |||
) | [static] |
Create a new buffering message.
This message can be posted by an element that needs to buffer data before it can continue processing. percent should be a value between 0 and 100. A value of 100 means that the buffering completed.
When percent is < 100 the application should PAUSE a PLAYING pipeline. When percent is 100, the application can set the pipeline (back) to PLAYING. The application must be prepared to receive BUFFERING messages in the PREROLLING state and may only set the pipeline to PLAYING after receiving a message with percent set to 100, which can happen after the pipeline completed prerolling.
src | The object originating the message. | |
percent | The buffering percent. |
