 just tried to replace A_QUICKTIME/QDM2 by A_QUICKTIME, but the resulting
 file cannot be played by any player i tried. So its not that simple
 Also please open a seperate ticket for the QDM2 issue, this one is about
 SVQ3 remux not playing in ffplay (which is fixed thus closing it)
 dont hesitate to reopen this ticket if svq3 isnt fixed, but please lets
 move qdm2 to a seperate ticket, so as to keep things easy to manage as
 these are 2 seperate issues
