I tried to use the command -movflags faststart
And got the following error:

The copyright date on your source code snapshot, as well as the build date of your binary (2011) indicate that the faststart feature had not yet been implemented in the FFmpeg codebase, which didn't happen until late last year, according to the source code; you might need a newer version of the program.
