Trouble with getting gst-launch conversion to keep audio.

Howdy! I’m following the instructions from this document (https://developer.download.nvidia.com/embedded/L4T/r32_Release_v1.0/Docs/Accelerated_GStreamer_User_Guide.pdf?snkWLJMt9GJtTMOyphMt9h5euGNyCurS2VIpGMDf2SRpBan6bHwtlabXQ20_DKQravroL9QAy-l6jiTNWiRLvz-2QUV_R1_EeQz4ZeoL5e-qAElBqQnrsnEVBUhtzpBPdzgY3AS_BG9jE1_jBN781auuuoWTiu9l7t_YYY1emLxc3XuU9oo)

I got an MKV video file (h264 blu-ray rip) converting using gst-launch, but it doesn’t keep the audio. Could someone here give me a sample command to do a conversion to hevc using gst-launch?

I should also mention, I’m ok with using software rendering for the audio portion of this, if it’s easier. I only need the hardware encoding for the video part.
