My name is Budi Kurniawan and I am a software developer at Orecx, a recording solutions company. We have recently developed a demux for playing FBS files. FBS is a format for recording computer screen sessions, in compliance with RFC 6143 (https://tools.ietf.org/html/rfc6143). I am sending a patch for the FBS demux. Kind Regards, Budi Kurniawan
