The rtspClient's share the same TaskScheduler, UsageEnvironment,<br>eventLoopWatchVariable and there is one doEventLoop() running (as in the<br>testRTSPClient project). <br></div></blockquote><div><br></div>Correct. Those are the only two choices, *if* you have also chosen to use just one process. (Note below.)</div><div><br></div><div><br><blockquote type="cite"><div>I've current implemented design 1, while I see option 2 being the intended<br>choice. The reason for picking 1 is the added "security" of keeping each<br>stream entirely independent, i.e. if an exception occurs for any reason only<br>one stream should be affected.<br></div></blockquote><div><br></div>Well, it depends on what you mean by "exception". If one thread has a memory access error, then it will kill the entire process. And there's nothing to prevent one thread (due to a bug somewhere) from stepping all over memory that's used by another thread. So there's really not much 'security' here at all.</div><div><br></div><div>If your streams really are "entirely independent", then why not use one process for each stream? That is by far the safest and most reliable approach.</div><div><br></div><div>But for some odd reason, here in the 21st century, the idea of structuring an application as multiple processes seems to have fallen our of favor...</div><div><br></div><div apple-content-edited="true">
