Is attached OK (for the interleaving, I didn't do seeking, yet, working on it)?

Output example, for a file where the first (default) chunk contains
stream 4 and the multirate chunks contain (in that order) chunk 0, 1,
2, 3 and 5, with the stdout giving (for each RM packet) the offset,
packet length, stream ID of packet and its PTS:

0x     b68: packet len=0480 id=4 pts=000000
0x     d54: packet len=0480 id=4 pts=000191
0x   5db03: packet len=0580 id=0 pts=000000
0x   5dd54: packet len=0580 id=0 pts=000232
0x   ba595: packet len=0564 id=1 pts=000000
0x   ba7d6: packet len=0564 id=1 pts=000278
0x  105dbf: packet len=0352 id=2 pts=000000
0x  105f2c: packet len=0352 id=2 pts=000255
0x  139e79: packet len=0564 id=3 pts=000000
0x  13a0ba: packet len=0564 id=3 pts=000139
0x  1d1c41: packet len=0480 id=5 pts=000000
0x  1d1e2e: packet len=0480 id=5 pts=000191
0x  13a2fb: packet len=0564 id=3 pts=000278
0x     f40: packet len=0480 id=4 pts=000382
0x  1d201b: packet len=0480 id=5 pts=000382
0x   5dfa5: packet len=0580 id=0 pts=000464
0x  106099: packet len=0352 id=2 pts=000510
0x   baa17: packet len=0564 id=1 pts=000557
0x  13a53c: packet len=0564 id=3 pts=000417
0x    112c: packet len=0480 id=4 pts=000574
0x  1d2208: packet len=0480 id=5 pts=000574
0x  13a77d: packet len=0564 id=3 pts=000556
0x   5e1f6: packet len=0580 id=0 pts=000696
0x  106206: packet len=0352 id=2 pts=000766
0x  13a9be: packet len=0564 id=3 pts=000696
0x   bac58: packet len=0564 id=1 pts=000835

Are these small variations in PTS acceptable or do you want me to
read-ahead to see which PTS (in future) will be smallest?
