copy nothing

flag indicating that buffer flags should be copied

flag indicating that buffer pts, dts, duration, offset and offset_end should be copied

flag indicating that buffer meta should be copied

flag indicating that buffer memory should be reffed and appended to already existing memory. Unless the memory is marked as NO_SHARE, no actual copy of the memory is made but it is simply reffed. Add GST_BUFFER_COPY_DEEP to force a real copy.

flag indicating that buffer memory should be merged

flag indicating that memory should always be copied instead of reffed (Since 1.2)
