Struct gstreamer::buffer::Buffer

source ·
#[repr(transparent)]
pub struct Buffer { /* private fields */ }

Implementations§

Creates a newly allocated buffer without any data.

Returns

the new Buffer.

Fills info with the GstMapInfo of all merged memory blocks in self.

flags describe the desired access of the memory. When flags is GST_MAP_WRITE, self should be writable (as returned from gst_buffer_is_writable()).

When self is writable but the memory isn’t, a writable copy will automatically be created and returned. The readonly copy of the buffer memory will then also be replaced with this writable copy.

The memory in info should be unmapped with gst_buffer_unmap() after usage.

flags

flags for the mapping

Returns

true if the map succeeded and info contains valid data.

info

info about the mapping

Appends all the memory from buf2 to self. The result buffer will contain a concatenation of the memory of self and buf2.

buf2

the second source Buffer to append.

Returns

the new Buffer that contains the memory of the two source buffers.
