Simple Server won’t play video – it’s really just a test/demo app.
There are loads of applications which support Syphon and play video – the grid on the Syphon website has quite a few – though many of them will be overkill for your needs, I can’t think off the top of my head of something which only does video playback.
What are you ingesting the Syphon server with? It’s somewhat unusual to have an application with Syphon input which doesn’t also play video itself.June 2, 2020 at 6:23 am in reply to: ofxSyphonServer texture is not properly backed. Cannot draw. #66952
Note I’ve recently updated the example projects for ofxSyphon – just small changes for OF 11, so you might want to do a git pull if you’re using those.June 1, 2020 at 3:18 am in reply to: ofxSyphonServer texture is not properly backed. Cannot draw. #66950
It would be easier to help you if we could see your drawing code, or if you supplied the simplest possible example which doesn’t work as you expect it to.
In the absence of any concrete information, what follows is pure speculation –
Syphon should work happily with Core Profile or Legacy OpenGL versions.
In ofxSyphon/example-Basic, there are two Syphon servers, to illustrate the two ways of using ofxSyphonServer. One publishes a texture, the other the contents of the window. If you just want to publish the contents of your OF window, then you don’t need an ofTexture and you don’t need to use
publishTexture()– in the example, you are only interested in what
mainOutputSyphonServeris doing. You can ignore code unrelated to it but you should pay attention to the sequence in which things happen – that is, draw what you want the server to capture, then call
Hope this helps – if not, show us some code – and if you have compilation errors, tell us what the errors are.May 30, 2020 at 2:57 am in reply to: ofxSyphonServer texture is not properly backed. Cannot draw. #66947
We’d have to see your drawing code to have any idea what’s going on.
Ah you could use something like Simple Client from the Syphon Simple Apps (download) to view the server. Perhaps we should add an option to Syphon Recorder to keep the preview during recording.
Yes this is done to maximise the resources available for recording. Is it a hinderance to your workflow?
Oh yes sorry, I should have started with that – Syphon doesn’t work in Sandboxed apps at present. Obviously we’re hoping to fix that in the future.
Can you post the commands you’re using to perform codesigning?
Difficult to diagnose without an Xcode project. Are you using Xcode’s Archive > Distribute toolchain for signing and notarizing, or doing it manually? Make sure everything you bundle only has x64 binaries – you might need to use lipo from the command line to strip 32-bit sections (or rebuild them from source).
Hey – sorry, for some reason your post got held back. Syphon is simply sharing a texture, so the problem must come in your drawing. Are you clearing the destination before you draw to it?February 14, 2020 at 4:05 am in reply to: Audio Garbled and Out Of Sync using v18 on OSX 10.15.2 Cataliina #66921
I know there have been problems with Soundflower on Catalina, which may or may not be the issue here. Have you tried BlackHole?
Hi – Syphon is only doing the work on the local machine to get video into QLab – the network part is handled by EpocCam/Airbeam. I’d suggest contacting them for support with their products. Good luck.October 7, 2019 at 4:26 am in reply to: Can't connect Syphon and Ableton 10 – help please!! #66898
Simple Server and Simple Client are basically test applications – you don’t need to have them running (or even installed) – though they can be useful for problem solving. You shouldn’t need to use SyphonInject either.
If you don’t see Vizzable/Ableton as a source in Syphon Recorder (or Simple Client), then it is a problem with Vizzable and the SyphonOut plugin. I know nothing about either of them, so I would suggest you seek help from their creators.
Glad to hear it’s working! Syphon Recorder has just had a major overhaul, so let us know if you hit any other issues.
Hi – and apologies for the slow reply. Can you specify how you are using Syphon (eg the apps you are using it between), or do you mean a particular Syphon app, eg Syphon Recorder?
Syphon itself works fine under Mojave.
At a guess you will have had the Apple Pro Video Formats installed on the old machine – they are installed automatically after you install FCP X, Motion or Compressor. I’m not sure if the current version includes the QuickTime codecs needed for Syphon Recorder, but it’s available here. If that doesn’t include the QuickTime codecs you may have to try to excavate them from /Library/QuickTime from a backup of the previous machine.
Syphon Recorder you mean? Syphon itself has been 64-bit from the start. Yep aiming to have a 64-bit Syphon Recorder before the next major macOS update, no promises though. In the meantime ignore the warnings, the current version works fine.
Mysterious – can you share a screenshot of the Preferences window?
I can’t tell from your description – are you using Syphon Recorder to do the recording? If so then there must be an audio device selected in the Preferences. Syphon Recorder > Preferences… then in the Audio section, set Input to None.
