 Yes, scr is now begin with 0, but it's not continuous,
 such as
 00:00:00.00 (0)
 00:00:00.00 (225)
 00:00:00.01 (450)
 00:00:00.01 (675)
 00:00:00.01 (900)
 00:00:00.01 (1125)
 00:00:00.01 (1350)
 00:00:00.50 (12233) -> it should be like 00:00:00.02
 00:00:00.50
 00:00:00.51

 i think this line in avformat/mpegenc.c
 line:985 scr= FFMAX(best_dts+1, scr);
 cause the scr jmp.

 and if it is possible, please do something with scr_ext, it's now 0
 anywhere.
 ----
 video stream should have both PTS and DTS in I and P frame, B frame only
 have PTS because its PTS=DTS
 PTS should have some time (like 00:00:00.04) later than DTS

 the first PTS of each stream should be same,
 and first PTS of video stream is AV_NOPTS_VALUE in current git head.
 ----
 by the way, what do rel_space,premux_packet and predecode_packet mean...
 i don't understand how to result "best_i".
