Member Function Documentation

static Glib::RefPtr<Gst::Event> Gst::EventBufferSize::create ( Format  format,
gint64  minsize,
gint64  maxsize,
bool  async 
) [static]

Create a new buffersize event.

The event is sent downstream and notifies elements that they should provide a buffer of the specified dimensions.

When the async flag is set, a thread boundary is prefered.

Parameters:
format Buffer format.
minsize Minimum buffer size.
maxsize Maximum buffer size.
async Thread behavior.
Returns:
A new Gst::EventBufferSize.
gint64 Gst::EventBufferSize::parse (  )  const

Get the minsize in the buffersize event.

Returns:
The mininum size.
void Gst::EventBufferSize::parse ( Format format,
gint64 &  minsize,
gint64 &  maxsize,
bool &  async 
) const

Get the format, minsize, maxsize and async-flag in the buffersize event.

Parameters:
format A reference to store the format in.
minsize A reference to store the minsize in.
maxsize A reference to store the maxsize in.
async A reference to store the async-flag in.
bool Gst::EventBufferSize::parse_async (  )  const

Get the async-flag in the buffersize event.

Returns:
The async flag.
Gst::Format Gst::EventBufferSize::parse_format (  )  const

Get the format, in the buffersize event.

Returns:
The format.
gint64 Gst::EventBufferSize::parse_max_size (  )  const

Get the maxsize in the buffersize event.

Returns:
The maximum size.
