I'm just getting started in Adobe Animate/CreateJS. I'm trying to control the timeline of a movie clip ("myMovieClip") on frame 1 on the main stage, preventing it from playing. According to the documentation, this should work:
this.myMovieClip.stop();
But it does not... the movie "myMovieClip" clip plays immediately on test in the browser, and I'm not getting any error love from the console. It's as if the above line of code wasn't even there.
This seems pretty basic. What am I missing? I ultimately want to stop all movie clips on the main timeline as well as a large group of nested ones. If there's a single command that does this, I'd love to hear about it.
I am fairly certain this is related to a bug in the Adobe Animate output that makes MovieClip timelines not immediately available.
You can get around this by forcing an update before you try to access the children:
this.gotoAndStop(0); // Forces update
this.myMovieClip.stop();
Hope that helps!

as my title says I am having trouble mapping face data from the Live Link app to a metahuman.
Here is what I have done so far:
Created a UE5 project (Film/Video & Live Event)
Imported a metahuman (custom-made) into the project
Added required plugins to project (Live Link, ArKit, Apple-etc)
Connected Live Link mobile application to local network
Set the metahuman's animation controller to the Live Link feed
Calibrated the Live Link data within the Live Link application
The problem I am having:
Parts of the face are not responding at all (ex. metahuman's right eyebrow does not respond to me lifting my left eyebrow).
The left corner of the mouth seems to be stuck (ex. when I try to open my mouth, all points respond except for the single point stays where it is).
The mapping/naming of facial components seems to be mirrored/off/labeled wrong (ex. if I was to wink my right eye this would result in my right eye closing and my right cheek pressing upward. On the metahuman, the left eye would blink and the right cheek would raise.)
These issues are very frustrating as I can not seem to get past this basic calibration. I see online people using these same tools and getting results with the metahuman's facial movements that are really clean. Is there something I am missing? I know that after the metahuman has been calibrated, I will create sequences, am I supposed to be modifying these value there? I am not sure... I have commented on every video I can find and I have posted this question in the Unreal Discord (here) with basically no help.
Note: I don't need a full solution, I just need to be pointed in the right direction! Please let me know if there is anything I am missing in my setup or calibration workflow.
thanks for reading.
Had the exact same problem with a customer project, and the issue was it wasn't using the correct animation blueprint. Once we switched it to the correct animation blueprint for LiveLink the issue was immediately resolved. I remember that exact same facial expression - sorry as I know this was a frustrating one for the customer as well.
It seemed that I was doing everything right. After upgrading from 5.0.3 to 5.1 the issue stopped completely.
I'm trying to make a 30sec video of images and can't seem to find useful information on how to achieve this if someone could point me to some examples would be great, other then that I got my script below I think dissolve should connect images is that right? What about how to connect first message window and make it appear first? Basically all three of these I want to go from to bottom as a video clip.
Script below:
MyMessage="Wireless Communications"
MessageClip(MyMessage, 320,240, text_color=color_antiquewhite,
\bg_color=color_blue)
Rails="C:\Users\me\Desktop\1.png"
RailClip=ImageReader(Rails,start=0,end=100,fps=25)
Info(RailClip)
PointResize(RailClip, 320,240, 0,20, 148,148)
Rails2="C:\Users\me\Desktop\3.jpg"
RailClip2=ImageReader(Rails2,start=101,end=200,fps=25)
Dissolve(RailClip+RailClip2,25)
error: 'frame sizes don't match'.
Ok so this question is actually in two parts.
I coded a video filter for VLC and I would like to add a control to the Video Effects panel on the OS X UI. So far I've been able to link my plugin the the UI by hijacking one of the existing controls, but this isn't ideal.
Now, if I open up the Xcode project (I'm running Xcode 6.3.1) and try to open the VideoEffect.xib file, I get the following error:
I tried to google this but it sounds like the only alternative would be to play archaeologist and dig up an old copy of Xcode 3. Is there any other way to be able to open this file and edit it somehow? I tried to look at the XML code but if I started to change that I'd do more damage than good.
The second thing I'd like to do is sending back values from the effect module to the UI. At the moment (by hijacking one of the existing sliders), all I can do is read a value from the panel with
config_ChainParse(p_filter, FILTER_PREFIX, ppsz_filter_options, p_filter->p_cfg);
p_filter->p_sys->i_factor = var_CreateGetIntegerCommand(p_filter, FILTER_PREFIX "factor");
and then, inside the callback function:
p_sys->i_factor = VLC_CLIP( newval.i_int, 0, 255 );
However, I haven't been able to write back the value. I'd like the filter to set p_sys->i_factor to a random value at start. This works (using var_SetInteger()), but it isn't reflected in the position of the slider in the Video Effect panel. I suspect I need to hack a bit deeper for that. Any ideas?
Regarding your first question with the xib-file. Consider downloading and using our forthcoming 3.0 code from git://git.videolan.org/vlc.git - it allows editing of said file without Xcode 3.
Regarding your second question, why would you want your video filter to interfere with the UI? This is not how the architecture of VLC works and there is no correct way to do it at this point. You would need to edit the core to do another global variable callback to ask the UI to reload the presented filter configuration.
Perhaps, if you give details about what your filter does and what you want to achieve, we find a more supported way :)
I've got a terminal application that needs to take a webcam picture and then perform some processing on it. I'm having trouble getting it to initialize. There's a fairly complete demo with an app called MyRecorder in the Apple docs that uses QTKit, which I was able to make work fine. I was also able to modify it to grab a single frame instead of a stream.
When I move this to a terminal application, the startRunning of the QTCaptureSession command simply does nothing. There are no errors, and everything reports as successful, but my webcam doesn't light up, and no frames are captured.
Any idea what's going on here? Are there any kind of security restrictions, or other kinds of restrictions that would prevent the QTCaptureSession from working?
So switching to AVFoundation solved my problem. I'm still not certain what the issue is, but for now using AVFoundation seems like the way to go since it was designed to replace QtKit anyways.
I've been programming for a while, but just recently decided to start developing for Mac OS X. I feel like I've come to grips with the basics of Objective-C and Cocoa development over the past week. I'm planning on making graphics apps, and as such am currently in the process of learning how to control Quartz compositions through a Cocoa app. I went through the tutorial that apple offers (with the Mac Engravings composition), and was able to create that just fine. In order to make sure that I truly understood what I learned, I decided to create my own composition and link it to a slightly more complicated Cocoa application.
Essentially, I have a composition that loads a movie or image through a Movie Loader patch, at which point it applies various filters to the frames before outputting it. In my Cocoa app, I've written code (or rather copied and pasted from other apple examples) that lets a user pick a file using an NSOpenPanel object. The filepath of the file they pick gets placed in a text-box that I placed in the app's window using Interface Builder. I binded the value of said text-box to the "Movie_Location" key in my composition, which is a published input in the Movie Loader patch that I'm using. However, no matter what I do, movies and images aren't loaded into this composition no matter what I try. The only thing that gets displayed is the default image that I have saved in that input from Quartz Composer (or nothing if I leave it blank before publishing).
I've added a Clear Color patch to the composition and binded that to a colorwell in my UI, and that successfully changes the color in my display, so I know that the composition and my Cocoa app are communicating. I've spent numerous hours at this point trying to figure out what's going on, and I've just about given up. Does the Movie Loader have any weird behaviors that I'm not aware of, or is there something obvious that I seem to be missing? I'd really appreciate any help or advice from anybody.
Thanks for reading through this...
Best,
Sami
There are two things I can think of as reasons why it is doing this:
The file path isn't formatted incorrectly. Try checking backslashes, colons, etc.
The box isn't updating the value. Try literally clicking in the text field and hitting enter.
That's all I can think of without seeing your quartz composition and/or code.
EDIT:
Check the other continuous box, in the general properties.
I figured this out yesterday. spudwaffle's second idea is what was going on. If I were to type a filepath in and hit enter, it would work just fine. I got this to work properly by just removing the bind and instead using the setValue:keyInPath: function that a patch controller offers. That said, is there some way to force a text-box to update? I remember seeing a "continuously update" or something like that button within the bind sub-menu in the inspector, but my code didn't work with that checked either.
Thanks to those of you that tried to help me! I really appreciate it.
Best,
Sami
