Hi Dan,

we are having crazy problems with the Multi Consumer.

We created a little playout system using the MLT Ruby bindings based
on the Playlist object and we are facing problems with seeking in the
playlist as soon as we switch to the Multi Consumer.

I have used your playlist.rb example code to reproduce the problem
with the least amount of code possible.

Here is the link to the code we used for testing:
https://gist.github.com/3804203
I have also included the log of my interaction with MLT and the
multi.yaml we used.

Seeking works nice and easy with no delay with the decklink consumer.

As soon as we switch to Multi, seeking does freak out on us.

In my example, when I seek the first time things freeze on decklink.
consumer.position stays close to where it was seeking from (can not
tell, if it stays exactly there or not).
pls.position seems to have jumped to the point I want to seek to plus
28 frames and freezes there. Eventhough speed is 1 and is_stopped is
false.
Stuff stays there for a while.
Most of the time the beginning of the sequence I was seeking to can be
seen on the output already. Could be that this is not the actual frame
I jumped to, but one in the range of it plus 28 frames, I can not
tell.
After at least 90 seconds, everything seems to continue normally.
The positions reflect the change and video playback continues.

On the second seek I was seeking backwards.
both, pls.position and consumer.position seem to be moving on as
nothing happened. But the picture freezes.
After a while things go back to normal again and pls.position and
consumer.position as well as the multi output have jumped to the
position I wanted to seek to.

Very weird behavior.

Can you tell me, where that is coming from or how to fix it?
Are forgetting any important config options on the two decklinks in multi?
Do we need to set anything on the multi consumer itself, like the
("rescale", "none") thing?

Please advise,

Markus
