The movie in the introduction restarts when changing slides.

[rasmusab]

First starting the movie on slide 15 in introduction/index.html and then pausing it and progressing to the next slide causes the movie to restart. As we are on a different slide now it is not possible to see the movie but the sound is still played.

This was on Firefox 6.0, Ubuntu 11.04, 32-bit.

Confirmed, and I should be able to get a fix in shortly.

Cool!

Otherwise I must say that deck.js looks fabulous!

Well... it wasn't what I thought, so I'll document what I've learned so far:

Gecko appears to rerender the Flash whenever it or any of its ancestors (the slide in this case) go in or out of a state of transform. The current active slide has no transform, while all others do. You'll notice that the Fade transition theme doesn't have this problem since it doesn't use CSS transforms. For whatever reason, at least for Vimeo, this means playing a previously paused movie. I haven't tested other video embedding services yet.

Giving deck-current a moz-transform equal to translate(0,0) does keep the video from reloading, but also completely renders all Flash useless. FF does not support Flash within a 0,0 translation (or within any transformed item at all it turns out). If anyone was curious, Webkit does. Though every browser that I've tested has problems with transforms that actually do some moving.

It looks like I'll need to do something special for FF until either they fix their transform bugs, Flash fixes them, or Flash dies in a fire. In any case, it may take a few days to figure out a good solution.

The above commit fixes this issue. If the iframe containing the video is in a nested slide it will still be unloaded, so it will blank out while in a before/previous state while nested, but this is far better than the annoyance of having a movie start off slide in a common workflow as it was doing before.

In the process of fixing this bug I removed the transforms on active nested slides in transition themes, which would have prevented video from working at all in nested slides in FF.
