The cur_dts is below this comment:

    /*****************************************************************
     * All fields below this line are not part of the public API. They
     * may not be used outside of libavformat and can be changed and
     * removed at will.
     * New public fields should be added right above.

So you must not use it.

I guess the way to determine the "stream position" (whatever that is) is
by looking at the first packet returned by av_read_frame() for the
stream.
