2626c02149 videorate: avoid useless buffer copy in drop-only mode 
Make writable the buffer before pushing it lead to a buffer copy. It's
because a reference is keep for the previous buffer.
The previous buffer reference is only need to duplicate the buffer. In
drop-only mode, the previous buffer is release just after pushing the
buffer so a copy is done but it's useless.

2102fdc983 discoverer: copy over result and seekable fields when copying a discoverer info 
The function gst_discoverer_info_copy doesn't copy the data members seekable
and result of the source GstDiscovererInfo.

In the case of copying a GstDiscovererInfo for later use, the seekbale will be
undefined, which in practice usually will be false, even though the seekable of
the original GstDiscovererInfo is true.

a7809ecc8f video-format: Fix macro documentation 
The parameter type was wrongly documenting that a GstVideoInfo structure
pointer was needed, while it needs a GstVideoFormatInfo structure
pointer.
