NDI decode/encode codec

Nate 2021-01-06 02:54:24 UTC in WMSPanel functionality

Is it possible to use NVENC to decode NDI, there doesn't seem to be an option to select any other codecs.

Also when I try using nvenc to encode it doesn't seem to be working.

Hello, Nate.

Could you please clarify, what are you trying to achieve?
If you want to use NDI as input, please select NDI as a source on the top of the 'Edit source stream' dialog, it will be decoded. No decoder will be available in this case.
If you want to convert NDI to another format, then choose codec to encode to. If it is not working, probably the NDI stream is not received by Nimble.
Please execute nimble_ndi on the Nimble server to check for available NDI streams for input.

I also suggest launching a ticket at wmspanel.com/help to continue the discussion, as we can request some sensitive information.

Thank you.

Q>Is it possible to use NVENC to decode NDI, there doesn't seem to be an option to select any other codecs.
A>No, nvenc doesn't support NDI decoding. The only method to do that is to decode using NewTech NDI library. This library doesn't use nvenc as of now.

Q>Also when I try using nvenc to encode it doesn't seem to be working.
A> take a look at logs to find what is wrong with your pipeline. If you cannot sort it - file ticket via https://wmspanel.com/help

I have sent in a ticket.

Yes, you can use NVENC, however I had to add a custom filter to get the transcode pipeline to work.

Add a custom filter with the following options:
filter Name: format
filter params: pix_fmts=yuv420p
