Tried to get it to work with NVPipe but always no display of image

Hi there, I tried to get this to work but it always shows a blank image - I tried many combinations of settings. I am using latest version of NvPipe. What can I do to find out how to get it to work?

Hi,

It seems jpeg compression is set by default in the client. Go to websocketConnection.js code, lines 17-18 and set

var jpegCompression = false;
var h264Compression = true;

On the other hand, use my NvPipe branch

https://github.com/benjha/NvPipe

or set H264 Profile to BASELINE in your NvPipe.cu in void recreate(...) method. It should looks like this, at the end of void recreate(...):

// SIGHT_FrameServer MOD: setting Profile BASELINE
if (this->codec == NVPIPE_H264)
encodeConfig.profileGUID = NV_ENC_H264_PROFILE_BASELINE_GUID;

        encoder->CreateEncoder(&initializeParams);

Broadway.js needs H264 Profile set to BASELINE.

Regards,

Benjamin

Thankyou it is working but. I don't like this change of code in NvPipe, couldn't this be added to NvPipe in a way that it becomes an option?

It's up to NvPipe developers. I think they wanted to design an API as simple as possible.
