site_archiver@lists.apple.com Delivered-To: pro-apps-dev@lists.apple.com I dug into this a little more. getBitmap works fine in Motion 5 (and Motion 4) as well as FCP 7 (although it's strangely upside down and the origin doesn't reflect this). In FCP X the call succeeds but the image is the grey image with arrow (like the drop zone in Motion when creating a Final Cut Effect). I noticed that both Motion 5 and FCP X return an 8-bit images, even if I request 32-bit. I don't really care about that part, but maybe it's related? I thought the new code is all floating point? Should I file this as a bug or an enhancement request? Any ideas for a workaround? I could cache an image from renderOutput but that gets very complicated with the new timeline rendering. It's further complicated by the [actionAPI currentTime] bug below but I "solved" that using the OSC time. Without a workaround we can't release our product. I'm calling getBitmap like this: FxRenderInfo renderInfo; memset(&renderInfo, 0, sizeof(renderInfo)); renderInfo.frame = t; renderInfo.qualityLevel = kFxQuality_HIGH; renderInfo.fieldOrder = kFxFieldOrder_PROGRESSIVE; renderInfo.scaleX = 1; renderInfo.scaleY = 1; renderInfo.depth = 32; renderInfo.sharedContext = CGLGetCurrentContext(); BOOL okay = [api getInputBitmap:&image withInfo:renderInfo atTime:time]; On Jun 30, 2011, at 10:17 PM, Garrick Meeker wrote:
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.
