muxers when streaming : explanations ?

[contremaitre]

Hi

I am confused with muxers when streaming, can someone explain me how it works ?

If i am recording a file with a muxer A. Then, later, I want to stream this file with muxer B.
I think the file is read with A_DEMUXER and then re-muxed with B_muxer and then sent to the network, right ?

But if I record and send the file with the same muxer, is it also demuxed/re-muxed ?

Finaly, are the stream container and the file container the same thing?

thanks

Yes, VLC always demuxes. When streaming a file to the networ, this is required to obtain timing informations and send data in real-time.
