I think so, yes.</div>

Because your video stream is H.264, rather than MPEG-1 or 2, you would
need to write a new "H264VideoStreamFramer" class, to parse
the H.264 stream into discrete NAL units. (You may be able to
use the existing "MPEG1or2VideoStreamFramer" class as a
model.<br>

<div>Probably not, because the presentation times that you want will
be those of the NAL units, not the PES headers.</div>
