Consumers receive uncompressed audio/video. Therefore, the consumer must 
invoke some encoder and muxer. So, will you use consumer_libdv or 
consumer_avformat or make it configurable? And how does one tell the existing 
consumer implementations of each of those to output using libiec61883 instead 
of a file. It is not possible in the current implementation, and it may be a 
little messy to factor that in, but should be possible.

Since I am the libiec61883 lead developer, I will explore this issue further 
since it is in my interest to figure out a good usage model for the community 
of its users. My thought is that by integrating it at a low level such as 
ffmpeg/libavformat, we make it available to many applications.
