NDI Using Singular Recast

Follow

At our company we use Recast in production. On a dedicated PC. Nonetheless, sometimes like always, you need to restart the software or reboot the PC. So I noticed: whenever you start Recast, it defaults to 'test' URL (not 'manual URL'. Even worse, even after selecting 'manual URL', it doens't use the previously entered URL. You still have to delete the URL in the URL-field, and paste your own Singular URL again. Only after this, and setting it onair (and choosing framerate and resolution) you can put it to air.

I found in the program-folder a 'Recast.exe.config' file. Opening this in notepad reveals some promising ideas. Is there a syntax/howto, to enter the needed info in this file, so I can have Recast start automaticaaly with:

• 'manual URL'
• my URL filled in
• 1920x1080 choosen
• 50p choosen
• 'myNDIname' filled in so it outputs NDI with this name always
• GPU on or off
• 'start' (so the software starts with above parameters already set, and is started to output NDI automatically)

Hi Jan, we recommend starting Singular Recast from the command line for your use case.

1. Locate the installation folder for Singular Recast runtime
cd C:\Program Files\SINGULAR.LIVE\Recast\cef-ndi

2. Start Recast using the command line:
cef-ndi.exe --width=1920 --height=1080 --fps=60 [--group={{your-ndi-group}}] --name={{your-ndi-name}} --url={{your-singular-output-url}}

Let us know if it works for you!

Tnx, for the very quick and to the point reply!

But not quiet there yet ... tried 2 things:

• a BAT script with this content (with and without different brackets as in your example, ... I don't see anything happening, Recast doesn't launch, also not 'invisible')
  @echo ON
  C:\Program Files\SINGULAR.LIVE\Recast\cef-ndi\cef-ndi.exe --width=1920 --height=1080 --fps=50 --group=Public --name=Singular --url=https://app.singular.live/output/6JgY4s4kIHkTFeSpQYQOrm/Output?aspect=16:9
• run the command you gave me straight from the WIndows prompt, gave me errors (especially GPU related errors. Which would be normal since this machine doens't have a dedicated GPU. So I need the GPU option turned off)

Hi Jan, you'll need to add the option --disable-gpu to the command line:

"C:\Program Files\SINGULAR.LIVE\Recast\cef-ndi\cef-ndi.exe" --width=1920 --height=1080 --fps=50 --group=Public --name=Singular --disable-gpu --url=https://app.singular.live/output/6JgY4s4kIHkTFeSpQYQOrm/Output?aspect=16:9

I've been wondering the same thing for a while. Same issue as jandewever. Using the --disable-gpu flag didn't make any difference.

Error from the console:

Hi Midway Covenant Tech Team,

The error message indicates that the cache folder is not defined, not accessible or locked. In such case, CEF will store cache data in the memory.When running multiple instances of cef-ndi.exe users should define the option --cache-path=C:/your-unique-cache-path in the command line.
E.g.

"C:\Program Files\SINGULAR.LIVE\Recast\cef-ndi\cef-ndi.exe" --width=1920 --height=1080 --fps=50 --group=Public --name=Singular3 --disable-gpu --cache-path=./Cache03 --url=https://app.singular.live/devices/2XfsEK1i863FAUcFOgOUJm?aspect=16:9

Is there a way I can download this for MAC?

Hi nightrunnerstudio at this time we only have a version of Recast for PC.

Hi, is it possible to use this to render any webpage? It seems that if I try another URL it just sends out black. We use it for the Recast GFX but it would handy to use it to render other webpages that we want in productions via NDI.

simon Singular Recast should be able to render any webpage into NDI, but we tested it only with Singular output URLs. There might be issues with other webpages we are not aware of. What webpage are you trying to render? Can you send us the URL so we can test it? Either here or in a new Support Ticket is fine.

Just as a test I was trying https://www.bbc.co.uk/

Hi simon can you verify if you are running the latest version of Recast? The download link is here. Our team tested it with that url and it worked fine.
