## Detailed Description

A class containing the format specification of a Gst::RingBuffer.

Gst::RingBufferSpec contains the format specification of a Gst::RingBuffer. The "in" members should be specified by the caller of the Gst::RingBuffer::acquire() method while the "in/out" members may be set by the caller but are also modifiable by Gst::RingBuffer::acquire(). The "out" members are generated as a result of the call to Gst::RingBuffer::acquire().

See also:
  Gst::RingBuffer::acquire().

## Constructor & Destructor Documentation

|  | int | segtotal = `0`,
|  | int | seglatency = `0`
| ) |  |

Fully construct a Gst::RingBufferSpec.

Only the "(in)" parameters are required. The "(in/out)" parameters are optional and may be modified by the call to the Gst::RingBuffer::acquire() method.

Parameters:

  caps | The caps of the buffer (in).
  type | The sample type (in/out).
  format | The sample format (in/out).
  sign | The sample sign (in/out).
  bigend | The endianness of the samples (in/out).
  width | The width of the samples (in/out).
  depth | The depth of the samples (in/out).
  rate | The sample rate (in/out).
  channels | The number of channels (in/out).
  latency_time | The latency in microseconds (in/out).
  buffer_time | The total buffer size in microseconds (in/out).
  segsize | The size of one segment in bytes (in/out).
  segtotal | The total number of segments (in/out).
  seglatency | Number of segments queued in the lower level device, defaults to segtotal in the C API (in/out).

Exceptions:

  std::runtime_error | if memory is unavailable for the new Gst::RingBufferSpec.

Gst::RingBufferSpec::RingBufferSpec | ( | GstRingBufferSpec & | castitem,
|  | bool | take_ownership = `false`
| ) |  | `[explicit]`

Construct a Gst::RingBufferSpec from a GstRingBufferSpec.

Gst::RingBufferSpec::RingBufferSpec | ( | const RingBufferSpec& | other | ) |
