Recoding flv video-streaming to MP4 format!

[lovej]

thanks for your reply ，Peter！

I place a queue after both parse elements, but the problem is still there！
from the debug information，I find that, when the difference between pts and
dts  is increasing to about 2s, the pipeline will block！ if
I only recode video, the difference will increase always. The dts is
calculated by h264parse.
