Trouble with getting gst-launch conversion to keep audio.

Howdy! I’m following the instructions from this document (

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.
