Comment (by hungnv):

 Update with -mpegts_copyts , -copyts and -vsync options.
 Source file:

 http://221.132.35.210/video0.ts

 Command I use:
 {{{
 fmpeg -y -i ~/video0.ts -vcodec libx264 -vb 500000 -s 640x360 -f mpegts
 -aspect 16:9 -g 25 -keyint_min 50 -vf scale=640:-1 -copyts -mpegts_copyts
 1 -vsync 0 ~/hung.ts

 }}}

 Duration, start time is still different
