I am getting the following error when I try to load video using video_decoder.

-> % qlua test-frame.lua -v 1DCnIad1Y0w.mp4 Unable to connect X11 server (continuing with -nographics) qlua: error loading module 'libvideo_decoder' from file './libvideo_decoder.so': ./libvideo_decoder.so: undefined symbol: av_frame_unref stack traceback: [C]: at 0x7fc4456649c0 [C]: at 0x7fc445439bd0 [C]: in function 'require'

What could be the issue? could you please help?

If you are getting this error, it means that you are making it with make NEWFFMPEG=1. Try making it without NEWFFMPEG=1.
