title: MPEG2 Presentation Time Stamps (PTS) calculation
body: <p>I have an MPEG2 TS file and now I am interested in extracting PTS information from each picture frame. I know that PTS is described in 33 bits including 3 marker bits. But I don't know how this bitfield can be converted to more understandable form (seconds, milliseconds). Can anybody help me please</p>
