[Libav-user] av_open_input_stream() with the new API

I am trying to open input stream,and I found an example which seems to be pretty
old : https://lists.libav.org/pipermail/libav-user/2009-May/003034.html
So I am moving step by step converting the old API to the new one.
Now I have this part:
AVFormatParameters params, *ap = ¶ms;
memset(ap, 0, sizeof(*ap));
ap->time_base.num = 1;
ap->time_base.den = 25;
DEBUG << "Opening stream" << endlog;
if( av_open_input_stream( &ic, &io, "",
fmt, ap ) )
DEBUG << "Can't open input stream " << endlog;
I see that instead of AVFormatParameters I should use AVDictionary.
But withint the
context struct I can't see any options like time_base.num or den,which
if I get it right,
set frame rate of the incoming stream.
So how do I pass the frame rate into this dictionary?
I also noticed that in almost every possible example in the web NULL
is passed instead
of the dictionary.Is it optional?
