I can play it in the default settings, but can't play with the desired streams,
both video and audio disappear.

I try to figure out what's wrong with it, 
and find the av_read_frame always read the stream index at 8 and 9.
It can reproduce from git source revision 9acffed9e0d7c454b7bc5c947f33cdf8cab3758c (cloned today.)
Just print which index the av_read_frame given.
