[Live-devel] Difference between H264VideoRTPSink an H264VideoFileSink?

[Benjamin Meier]

Hi,
we are implementing a Transcoder, who:
1. receives  a couple of several demuxed H264/SVC Streams via RTSP from 
another machine
2. muxes the several streams into one big stream
3. should send this big stream into a RTPSink to stream it to the 
clients via Multicast
But here we are in trouble. When using a H264VideoFileSink, everythings 
working like a charm, the created file is like the one the whole 
streaming started with. So I'm supposing everything about our code is 
ok. Using the intented H264VideoRTPSink to stream the muxed stream to a 
multicast-address leads us to the error "attempting to read more than 
once *at the same time".*

Can you imagine why the FileSink is working contrary to the RTPSink? 
What might be the basic difference between RTPSink and FileSink?

Thanks!
Benjamin
