No, in-band extradata works ok too (SPS and PPS are just included in the
stream, and the player can succesfully play it). AFAIR, DVB-H even
recommended such a solution (ISMA and other standards mandated out-of-band
global headers, but AFAIK no RFC requires that).
Anyway, just try the command line above (adding "-re"), and you will see
that it works.
