Syphon server/client support

Hey @diccon,

See this video for using DSLR in Zoom:

Thanks,
Tommy

@tommy
Thanks. I use the Magewell SDI capture discussed in the first part of the video. Ecamm is a neat solution. (CamTwist is free, and similar.) However, Zoom disabled virtual cameras a few minor releases ago. So 50% of the solution (for the key application being asked about in this thread, really) doesn’t work. Do you have an ETA on re-enabling virtual cameras, perhaps with a Zoom virtual camera loopback device to avoid the code signing library entitlement issue that was (I imagine) why it was disabled? This has had a significant impact on our flexibility for multimedia projects/courses/events using Zoom.

Hey @jburke,

I don’t have an ETA on the virtual cameras - I’d reach out to support.zoom.us for better assistance as this forum is for the Zoom App Marketplace.

Thanks,
Tommy

    That would be really very useful !

@tommy

For what it’s worth, I want try again to strongly advocate for the addition of Syphon / Spout support as an input source to Zoom.

(I am the creator of a software called Isadora, a desktop application for Mac and Windows used by several thousand users worldwide that enables real-time manipulation of video and audio.)

While the NDI Virtual camera is one solution, it has some notable limitations: it is CPU heavy and it introduces a very noticeable delay, on the order of at least half a second and usually more.

Because Syphon and Spout use texture sharing, they have no measurable latency, introduce a nearly zero performance hit, and – importantly – are offered as both an input and and output by nearly every media server application in existence. (See a list of notable applications at the bottom or peruse the long list you can see on the Syphon home page at http://syphon.v002.info)

Why is that important? Because theaters and galleries are going to remain closed for months. Those who work in the performing arts are going to need tools to support remote performance. While NDI Virtual Input does allow input from some of these media server applications, Syphon and Spout are hands down a much better solution to ship video from one application to another.

Both are open source and thus it is easy to prove they are secure by examining the code. Both have liberal open source licenses that would allow you to use them with commercial software. My experience implementing both for my software proved to me that – if Zoom can accept OpenGL or DirectX textures as an input – your development cycle will be quite short and thus inexpensive.

I hope that some of the points I’ve made above might cause someone on your team to reconsider supporting Syphon and Spout.

I second this. I’m preparing several concepts to pitch to a few museum and location-based entertainment clients which would involve piping realtime video feeds from our interactive video systems through a video conference. Would love to use Zoom if we’re able to get a Spout into it. Otherwise we’re looking at NDI into Skype which is not our preferred method.

I agree and think it is critical for Syphon and Spout to be integration into Zoom as soon as possible.

Same here. I am working as a media teacher. During Corona-time I was forced to teach online. I would love to see the Syphon/Spout integrated into Zoom…

I am writing to request the support of Syphon natively within Zoom.

As a professor at The Ohio State University I make this request for our Department of Theatre, The Advanced Computing Center for the Arts and Design, and as the Vice Commissioner of Technology for United States Institute for Theatre Technology. Zoom holds a special place in the tool set that we as theatre and media professionals are using RIGHT NOW during this global pandemic. Syphon is an important tool that our industry relies on to minimize latency and provide seamless networking between media servers and our distribution outlets.

Please consider this request not just a lone voice but that of a representative the over 22,000 members of USITT and thousands of theatre, film, dance, and transdisciplinary theatre and media students and artists at OSU that would directly benefit from the addition of this feature.

I think there is a hack for this, using “codesign --remove-signature /Applications/zoom.us.app/” to enable using an external webcam with Zoom and using CamnTwist to create a virtual Camera with a Syphon input

Unfortunately, Syphon and Spout are not a virtual webcam. They are a completely different technology than a webcam and would require Zoom to specifically add them as a possibility.

@Tommy

Can you chime in on this discussion? Is it possible that you / the Zoom development team might reconsider adding Syphon and Spout as an input? Really they are so many that would benefit from this… those that have added their support above are just the tip of the iceberg.

Best Wishes,
Mark

That’s where CamTwist comes in… It creates the virtual camera Zoom can use

Hi folks,

I’m here to echo the requests of the users before me. We would really like to see Syphon integration within Zoom.

Zoom may have very abruptly cornered the market on bringing people together during this time of global crisis - but with no end method in sight for resuming in-person large events, the performing arts community is very quickly going to start looking elsewhere for a platform that can readily provide high-quality mixed media video support. And the screen share tool is just not cutting it.

I’ve worked in professional sports, TV broadcast, touring concerts and shows, contemporary worship megachurches, regional theatre, and higher education - and though the software used in each of those disciplines is varied, the common thread among them is some sort of frame sharing interoperability.

Please reconsider adding Syphon/Sprout integration to a near-future release of Zoom. We would appreciate hearing from @tommy or other members of the staff/Developer Advocates soon so that we can make plans for how our teams will move forward.

This is actually a real problem!!! Please make Syphon/Sprout available again as video input as quick as possible!

I want to throw my support into encouraging Zoom to develop Syphon compatibility for its product.

I am a theatre technician, designer and creator who normally works in dark black rooms delivering sound and video content that make engaging, entertaining (hopefully) live theatre performances. Right now the theatres are all shut here in the UK so my world has shifted to working with performers who are exploring how to make live Zoom based shows.

My main tool in theatre AV is Qlab (https://qlab.app/) which is the top notch market leader for delivering audio and video…it works seamlessly with Syphon and if Zoom supported Syphon I can see the opportunities for Zoom to become the go to product for delivering live theatre into people’s home!

Right now, I am involved with an interactive musical version of production of Shakespeare’s Twelfth Night…mixing live actors with pre-recorded sections for songs…I share a second screen into the Zoom Performance (we don’t do meetings), showing the content cued by Qlab. This is great…it works…BUT give me the creativity to add in video (from Qlab via Syphon in Zoom) as a web cam in the Gallery view or as a Spotlight. Wow this is exciting.

Anyway you can see I want this feature

Cheers

Si

I can’t get CamTwist to work with Zoom 5.0.4. Does it?

+1 for zoom to support syphon!
