yea ofxSyphon seems to be all over the internet in various forms…
If I clone and install astellato’s github version (it has the newest code) and follow his installation instructions, the example works for me (I moved it to OF/examples/addons).
OF is annoying in its hierarchy of folders, and its habit of occasionally changing them between releases which breaks all sorts of things. Make sure the example project can find the ofxSyphon addon.
You probably don’t mean lagging. Do you see a low framerate in the resulting movie? If not, describe what happens.
What codec have you selected in Syphon Recorder? If you choose Syphon Recorder Help from the Help menu there are some tips about selecting an appropriate codec.
At a guess, it is likely that your disk is struggling to keep up. This will be the case if you are playing movies from the same disk as you are recording to. Try playing from or recording to a different drive.
Resolume 3 has no native Syphon support. If you don’t want to upgrade to 4, you can install the Syphon FFGL plugin (download) to have a server appear as an effect in Resolume.
Nothing else need be installed. If you have the Syphon checkbox marked in Avenue like this, and nothing is happening, try posting to the Resolume forum for help.
The VDMX record function should work. If you’re having problems with that use the built-in bug-reporter in VDMX (Help > Report Bug).
In Modul8, use Output > Syphon (or command-Y).
Both VDMX and Resolume need you to specifically enable Syphon
In VDMX
Plugins tab of the Workspace Inspector > + > Syphon Output then check the box for the layer you want to send.
In Resolume
Resolume menu > Preferences > Video > check the Syphon box
Ah yes, other people have had problems with audio from some hardware which I am unable to reproduce.
I will look into it. If you’d be willing to help me try to track the problem down, drop me an e-mail to bangnoise@gmail.com
Also just run it in the debugger and step through it and see where it fails. If that’s beyond your comfort levels with Xcode then use Apple’s player.
Those errors are from a composition with the older v002 Movie Player. Make sure you’re running the correct composition.
IIRC the Media Tools movie player doesn’t currently support partial path names, etc, so give it the FULL path to your movie file.
Could you check you can record another Syphon server without problems? It sounds like it isn’t limited to your video source if it still happens when capturing the OpenGL scene.
Also try not recording sound, to see if the problem persists. I’d like to solve this if possible.
Can you tell me what Mac OS version and Mac you’re currently using? A screenshot of the Preferences window in Syphon Recorder would also be a help.
Cheers
Try the build mentioned above, check you have the correct path to your movie. Check the ProRes codecs are installed (ie you can play the movie in QT Player).
You don’t say what OS you’re building on or what error(s) you get in Xcode. Check you have populated the v002 Utilities submodule with
git submodule update --initUse whatever works for you. The stuff on GitHub is generally not a polished release and a lot of it (such as the Media Tools) is us trying stuff out.
Further re VDMX, Ray has just reminded me that you can limit the render rate (soz if you already know this)
– VDMX5 > Preferences… > Rendering
– Scroll down to reveal the hidden Advanced Rendering Prefs button and hit it
– Uncheck Display Drives Canvas Rendering
– Alongside its dimensions, your Canvas/Main Output will now have a FPS setting – set that to whatever seems reasonable – probably the rate of your original video sourceIt’s not going to give you true sync, but coupled with only rendering in OF on new frames it should improve things quite a bit
For what it’s worth, as of yesterday there is a new version of Syphon Recorder. None of the Syphon capture stage has changed, so I doubt it will fix your problem.
1. okay – something strange is definitely happening.
2. If you see nothing on the Billboard in QC then you’re not doing it right. The Billboard needs to be layered below the Syphon Server. The output of the Video Input patch should be connected to the Billboard’s Image input (and not to the Syphon Server). Once you can see the image in the QC viewer it should also show up in Syphon Recorder (with the dimensions of the QC viewer window). Try recording that.
5. I would guess yes but it would really be worth trying it if you can get your hands on one before you buy.
Yo and cool –
SyphonClient has a hasNewFrame method which you could extend ofxSyphon to expose, then only do work when that returns YES.
This will be of some but limited use if the server is running in VDMX, as VDMX has little to no notion of throttling things down when it can.
On this Macbook Air with Intel HD 4000 I can record AIC 1080 HD at 60 FPS, so yes, I think a MacMini would be up to the task.
Hi – can I just check I understand your problem?
In QC you have Video Input (Apple’s Video Input patch) -> Syphon Server
In the recorded output you only get one frame– Do you see moving video or a frozen frame in the preview in Syphon Recorder (View > Show Preview if it is hidden)?
– I take it the Syphon Server is in Image mode, not Scene? What happens if you try Scene and connect the Video Input to a Billboard patch?There’s no reason you can’t expose the texture as a texture if that’s of any help and you want to modify ofxSyphon to allow it (ofxSyphon would love the attention). Just be aware that the texture is dependent on the lifetime of the Objective C SyphonImage object, so don’t release it while it might still be in use by OF.
As OpenCV needs pixel-buffers from it you will have to copy it via an FBO to get those – for the reasons discussed in that thread. Holler if we can give you any pointers – sounds like you’re on your way though.
