However, the VBI data stream packets do not have PTS/DTS specified, which means that the FrameConstructor does not assemble frames properly. <BR /><BR />This also happens when I write the stream with UMC 5.2, since it does not assemble PES headers (with PTS/DTS) for VBI data. It only puts a TS header onto each packet and splits the data verbatim over as many 184 byte packets as needed. <BR /><BR />Twofold question:<BR />1) How do I read VBI data that has no PTS/DTS (in a PES header)?<BR />2) How do I write VBI data that I can read again?<BR /><BR />Thanks, <BR />Tilman. <BR /> Fri, 31 Aug 2007 18:22:45 GMT https://community.intel.com/t5/Intel-Integrated-Performance/VBI-data-stream-PTS-DTS-problem/m-p/911294#M14291 intel6 2007-08-31T18:22:45Z https://community.intel.com/t5/Intel-Integrated-Performance/VBI-data-stream-PTS-DTS-problem/m-p/911295#M14292 Sorry, forgot to mention: I'm using IPP5.2/UMC5.2 for this (latest versions). <BR /> Fri, 31 Aug 2007 18:23:29 GMT https://community.intel.com/t5/Intel-Integrated-Performance/VBI-data-stream-PTS-DTS-problem/m-p/911295#M14292 intel6 2007-08-31T18:23:29Z
