VLC could not open the mp4a audio encoder

I am attempting to use the Convert/Save feature of VLC to convert an mkv file to an mp4. (H.264 video with MPEG-4 AAC audio)

I get the following error:

VLC could not open the mp4a audio encoder

How can I remedy this? VLC 2.2.4 on Windows 10.

Thank you!

Go to Tools > Preferences > Input/Codecs > Video codecs > FFmpeg Changing the 'Strict standard compliance to -2 worked for me.

Found this method here: Streaming / Transcoding failed

On OS X, you select VLC menu and then Preferences. Then click Show All at the bottom left. Then under Video Codecs in the left pane, select FFmpeg, scroll halfway down and change Strict standard compliance to -2.
