Hi Heres a third try, the first was transmit_ts with unspecified buffers second was transmit_ts with a single specified buffer Here now comes the buffer state per syncpoint. It trivially allows the demuxer to find the needed preload, and allows trivial clock synchronization. Iam not sure how much more or less device dependant this is. It surely looks better if one considers broadcasting at a higher bitrate than the intended one. (lower will fail as with all other proposals) Also this is the smallest solution so far, and likely also has less overhead than the transmit_ts. -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Dictatorship naturally arises out of democracy, and the most aggravated form of tyranny and slavery out of the most extreme liberty. -- Plato
