[Ffmpeg-devel] opening multiple streams

Hey all,

I am working on an application that receives multiple RTP streams (audio
and video) and should display them at the same time. 

I got this kind of working but am running into problems with
av_find_stream_info(...), which as i understand can not be called from
more than one thread at the time, is this true ?

The call to av_find_stream_info(...) takes a very long time, what could
be the reason for this ? Could i eliminate the call completely ? I
receive the stream information, like if it is MPA, MP2T, MPV etc. out of
bound so could i setup things to know what the stream is before opening
it and skip the av_find_stream_info(...) call ?
