The "writing to a file" would be done directly (i.e., using "fwrite()"), rather than using a "FileSink").</div><div><br></div><div><br><blockquote type="cite"><div>If I should do so, how about send to 2 and more live player</div></blockquote><div><br></div></div>The simplest way to do this is just to use multicast. I.e., send the frames out just once (using a single "RTPSink" object, but do so using an IP multicast address). (E.g., our "testRelay" demo application does something like this.)<br><br><div apple-content-edited="true">
