site_archiver@lists.apple.com Delivered-To: pro-apps-dev@lists.apple.com Reported as Bug ID# 9714238. Hmm, the last render time seems fragile with all the timeline rendering happening. Maybe get the time from an on-screen control? Any thoughts about checking out images from on-screen controls or parameterChanged? Should I file this as a bug or an enhancement request? Is there anything I can do now other than cache images from render calls? FxHostCapabilities always reports Motion now, right? Do I need to look at the id of the application bundle to figure out if these workaround are necessary? On Jul 1, 2011, at 9:53 AM, Darrin Cardani wrote:

Garrick, This appears to be a bug that we aren't propagating the current time in some cases. Please file a bug.

As for workarounds, one option would be to use whatever was the last render time if currentTime comes back as 0. It's fragile, but may be better than nothing.

I'm seeing some issues here that could seriously affect our products. First, we get the current time in the parameterChanged method with:

id <FxCustomParameterActionAPI> actionAPI = [_apiManager apiForProtocol:@protocol(FxCustomParameterActionAPI)]; double t = [actionAPI currentTime];

That works in Motion 5 and has always worked before, but in FCP X it seems to always be 0.

And we also need access to images outside of renderOutput, specifically in parameterChanged and from on-screen controls (or custom UI in FxPlug 1). I realize this isn't guaranteed by the API but it works in Motion 4 and 5. FCP X seems to return a solid color. I've only tried the bitmap calls here. Stuffing the current OpenGL context into an FxRenderInfo to get a texture seems problematic. Trying to cache a frame from the render calls seems difficult too because of FCP's timeline rendering.

I can file a bug but I'm really hoping there are workarounds for this release.
