Hello Fu Qiang,
There is not VLC recipe available as part of the Yocto BSP release or Community BSP.
There were some efforts by third parties to integrate VLC on i:MX boards in the past (link below)

However, I haven’t heard of efforts in newer layers. VLC is open source so you may write your own Yocto recipe, although this is not a trivial task.
My apologies for the inconvenience!
Regards,
