You should not do that. The PTS is only the presentation time
stamp. There is also a DTS which is the decoding time stamp. Since B
frames depend on frames that precede and follow them, those frames (I-
and B- frames have to be present before the B-frame can be
decoded. That's why the frames don't come in order.

The buffer limit is in the hardware. That's why you need correct muxing.
