Thank you for the response. I will investigate this, but it doesn't quite<br>
make sense to me. I can certainly understand that the split can't happen<br>
except at the end of a GOP, but aside from that why would splitmuxsink be<br>
any different from any other mux/sink in its requirement to wait for a<br>
complete GOP before passing to the muxer (in my case matroskamux) sink?<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">I believe the speed at which data is mixed is not controlled, it should pretty much reflect the source behavior.</div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
