When generating mpeg-ts stream using ffmpeg, I have observed, that PCR
marks are spaced too far apart one from another. Typical PCR period is
about 60 - 70 ms which is a way too much. Another problem is that this
value considerable varies at some moments. Especially on dynamic scenes
I have seen extraordinarily big PCR periods ranging to several hundreds
of milliseconds. Because of this I have disordered timing in output
module which sends created stream to network QAM modulator
(http://www.dektec.com/Products/IP/DTE-3114/). My output buffer can
accomodate max. 250 ms block of data. I have suspicion that this is a
ffmpeg bug, but not sure. Has this happened to someone?
