Andoni Morales Alastruey fcf2d8c350 videodecoder: fix segfault copying buffer metas 
The current implementation copies metas without checking if the buffer
is writable.

The operation that needs to be done, replacing the input buffer and
copying the metas, is only part of that process. We create a new function
that does both.
