Hello All,
I possess just enough knowledge of ffmpeg to be dangerous, but
I'm assuming that a recent problem I've run into is most likely
related to a H.264 time stamp issue, as in the following ......
-----------------------------------------------------------------------------------------------------------------
ffmpeg -i test1.m2ts -vcodec copy -an -f mpegts -ps 192 copy.m2ts

Am I correct in guessing that these last two lines are time stamp
related? If so, is there a
work around available, or is this something that may be addressed in the
future?
Thanks for your help.
Cheers,
Bill Crowley.
