caps or undef = $buffer->get_caps

$buffer->set_caps ($caps)

  • $caps (GStreamer::Caps)

GstBuffer = $parent->create_sub ($offset, $size)

  • $offset (integer)
  • $size (integer)

scalar = $buffer->data

void = $buffer->data_ptr

$buf->set_data ($data)

  • $data (scalar)

unsigned integer = $buffer->duration

bufferflag = $buffer->flags

boolean = $buf1->is_span_fast ($buf2)

  • $buf2 (GstBuffer)

GstBuffer = $buf1->join ($buf2)

  • $buf2 (GstBuffer)

GstBuffer = $buf1->merge ($buf2)

  • $buf2 (GstBuffer)

64 bit unsigned = $buffer->offset

64 bit unsigned = $buffer->offset_end

integer = $buffer->size

GstBuffer = $buf1->span ($offset, $buf2, $len)

  • $offset (unsigned)
  • $buf2 (GstBuffer)
  • $len (unsigned)

$dest->stamp ($src)

  • $src (GstBuffer)

unsigned integer = $buffer->timestamp
