Running ffserver with cuda hw acceleration

Postby akwolf » Tue Dec 20, 2016 11:40 pm

Hello! I am trying to stream to an ffserver but am having some issues. I am using ffmpeg to stream to the ffserver, and the command that I am using is:

Code: Select all
ffmpeg.exe -hwaccel cuvid -c:v h264_cuvid -i input.h264 -c:v h264_nvenc -profile:v high444 -pixel_format yuv444p X.X.X.X/feed1.ffm

When running this command, I get the following error: "CUVID hwaccel requested, but impossible to achieve". I think this is because the ffserver is not running with hw acceleration enabled. When I run the ffmpeg command above with output to a file instead of ffserver feed, I don't receive any errors.

I have found this command in the ffserver guide, hwupload_cuda (ffmpeg org/ffserver-all.html#hwupload_005fcuda-1) but I am unsure on how to use it. Does anyone know on how I can add this command to my ffserver.conf and if this command would help with my problem?

Also when checking decoders on ffserver, cuvid does show up:
