- you can use filesink to make a recording. first please run /opt/nvidia/deepstream/deepstream/user_additional_install.sh to install software encoder because A100 does not support hardware encoding. then please set type=1 in [sink0], and set enable=1, enc-type=1 in [sink1].
- please refer to this topic. A100 is not display card. you can set up a virtual display.
