Detailed Description
A buffer size event.
See create() for more details.
Member Function Documentation
◆ create()
|
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 preferred.
- Parameters
-
format Buffer format. minsize Minimum buffer size. maxsize Maximum buffer size. async Thread behavior.
- Returns
- A new Gst::Event.
◆ parse()
| 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.
◆ parse_async()
| bool Gst::EventBufferSize::parse_async | ( | ) | const |
Get the async-flag in the buffersize event.
- Returns
- The async flag.
◆ parse_format()
| Gst::Format Gst::EventBufferSize::parse_format | ( | ) | const |
Get the format, in the buffersize event.
- Returns
- The format.
◆ parse_max_size()
| gint64 Gst::EventBufferSize::parse_max_size | ( | ) | const |
Get the maxsize in the buffersize event.
- Returns
- The maximum size.
◆ parse_min_size()
| gint64 Gst::EventBufferSize::parse_min_size | ( | ) | const |
Get the minsize in the buffersize event.
- Returns
- The mininum size.
