When you use ''-movflags +faststart'', FFMPEG muxes the file, then muxes
it again, moving all the metadata about all packets to the beginning of
the file.
However, when it comes to Matroska, using ''-reserve_index_space'', one
has to mux it manually, and then get the error, using the info given in
the error, mux it again with the right value for reserved space.
Is there a way to optimize it, like ''-movflags +faststart'' and let
FFMPEG choose what space is necessary and automate it?
