I have encountered the same problem, I solved this problem but I don't
know why it works.

old test.c:

#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>

int main()
{
	av_register_all();
	return 0;
}


new test.c:

#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>

int main()
{
	avcodec_register_all();
	av_register_all();
	return 0;
}
