Comment:

 Hello there,

 Are you running this on a physical Tesla T4 or on a vGPU-based T4
 instance, such as that provided by VMWare's vSphere on ESXi, etc?

 Can you show us the output of:

 1. nvidia-smi

 Just run:

 {{{nvidia-smi}}}

 As is, followed by:

 2. GPU topology information via:

 {{{nvidia-smi topo -m}}}

 Your results are indeed abnormal and are most likely not related to
 FFmpeg, but your system's config. The output from the commands above will
 help verify that.
