Simple gst-launch playback on A100?!

I’ve just stated toying with gstreamer and deepstream (ngc container 6.1) on a machine with a A100, and cannot figure what to change in the second cmd below to get it to work like the first:

$ gst-launch-1.0 filesrc location=/path/sample_720p.h264 ! h264parse ! avdec_h264 ! nveglglessink

$ gst-launch-1.0 filesrc location=/path/sample_720p.h264 ! h264parse ! nvv4l2decoder ! nveglglessink
Setting pipeline to PAUSED …

A100 is not display card, it’s compute card. you can try to setup virtual display, following Deepstream/FAQ - 5A, but it’s for Tesla series. you can give it a try.

Hello @amir7 Do you need further support? I think we can close the topic here.

is it possible to run the deepstream examples with this setup by letting the cpu handle the encoding part? If so could you point me to where I can see the code for it?

You can refer to deepstream-app, which support hardware encoder and software encode, you can set in config.
#encoder type 0=Hardware 1=Software
