Copy VP9 stream and transcoding opus

I have some video files with VP9 video codec and opus as audio codec. My Sony UBP-X700 is not able to handle the Opus codec, so I would like to convert only the audio stream leaving the video stream intact. I tried with a very simple profile but it doesn't work. Is it possible to transcode the audio and copy the video stream as is?

  Code:

<Profile id="UBP-X700" name="UBP-X700 " extendsProfileId="1">
      <Detection>
         <UPnPSearch>
            <ModelName>UBP-X700</ModelName>
         </UPnPSearch>
      </Detection>
      <Transcoding>
         <Video targetContainer="mpegts" targetACodec="ac3">
            <Matches container="*" aCodec="opus" />
         </Video>
      </Transcoding>
   </Profile>

I found some warnings in the log

  Code:
