Gst::FlowReturn Gst::AppSrc::push_buffer ( const Glib::RefPtr< Gst::Buffer >&  arg0)

This is a convenience method for the action signal signal_push_buffer().

Glib::SignalProxy0< Gst::FlowReturn > Gst::AppSrc::signal_end_of_stream ( )

This is an action signal which is designed to be used as a method.

To do that, use its convenience method, end_of_stream().

Slot Prototype:
Gst::FlowReturn on_my_end_of_stream()

Notify appsrc that no more buffer are available.

Glib::SignalProxy0< void > Gst::AppSrc::signal_enough_data ( )
Slot Prototype:
void on_my_enough_data()

Signal that the source has enough data. It is recommended that the application stops calling push-buffer until the need-data signal is emitted again to avoid excessive buffer queueing.

Glib::SignalProxy1< void,guint > Gst::AppSrc::signal_need_data ( )
Slot Prototype:
void on_my_need_data(guint arg0)

Signal that the source needs more data. In the callback or from another thread you should call push-buffer or end-of-stream.

length is just a hint and when it is set to -1, any number of bytes can be pushed into appsrc.

You can call push-buffer multiple times until the enough-data signal is fired.

Parameters
lengthThe amount of bytes needed.
Glib::SignalProxy1< Gst::FlowReturn,const Glib::RefPtr<Gst::Buffer>& > Gst::AppSrc::signal_push_buffer ( )

This is an action signal which is designed to be used as a method.

To do that, use its convenience method, push_buffer().

Slot Prototype:
Gst::FlowReturn on_my_push_buffer(const Glib::RefPtr<Gst::Buffer>& arg0)

Adds a buffer to the queue of buffers that the appsrc element will push to its source pad. This function does not take ownership of the buffer so the buffer needs to be unreffed after calling this function.

When the block property is true, this function can block until free space becomes available in the queue.

Parameters
bufferA buffer to push.
Glib::SignalProxy1< bool,guint64 > Gst::AppSrc::signal_seek_data ( )
Slot Prototype:
bool on_my_seek_data(guint64 arg0)

Seek to the given offset. The next push-buffer should produce buffers from the new offset. This callback is only called for seekable stream types.

Parameters
offsetThe offset to seek to.
Returns
true if the seek succeeded.
