[Libav-user] Question about usage of libav in an application

I'm writing an application that will be ingesting multiple live streams at
once and managing them, and to do this I've been adapting libav with a
custom AVIOContext. The custom context is simply reading from an FLV file
for testing purposes before I will feed it an RTMP stream. All of this is
tested + proven.
Everything works fine when only one stream is being ingested, and I'm quite
sure I'm going by documentation on this, however when I have multiple
streams running at once libav runs into problems reading in packets.
There is a lot of code to review for this issue I'm having, so I won't
bother attaching it all -- but I do have one question concerning the
behavior of libav:
1. Is it possible to read/decode more than one media stream in one
single thread? i.e. round-robin each AVFormatContext, calling av_read_frame
once, decoding, and moving onto the next packet/frame in this fashion?
2. Or, is it possible to achieve the same thing, with each stream being
on its own thread (constructing the AVFormatContext, reading input,
In essence, I am looking to decode multiple streams in one process. Hope
this is possible, if it is there is likely something wrong with my code
