VLC on buildroot image could not load codec plugins while they're presented

We've managed to build up a buildroot X11 image for Raspberry Pi 4 with vlc package enabled(beside ffmpeg + libopenh264 and other dependencies). so we can run vlc like this vlc --verbose=2 --file-logging --logfile=vlc-log.txt xbody.mp4 while ffmpeg libavcodec.so and vlc libavcodec_plugin.so are present on target image and also we can play with gst-play-1.0.

But VLC show error and fails to play media:

Codec `h264' (H264 - MPEG-4 AVC (part 10)) is not supported

And also as expected vlc --list doesn't list codec module.

So why it can not load codec modules?
