 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?
