What steps will reproduce the problem?
1. Write a simple main program tp open a file
What is the expected output? What do you see instead?
Expected: An extracted frame.
Instead: The openFile functions fails in the
pCodec=avcodec_find_decoder(pCodecCtx->codec_id); line, which returns NULL.
Probably because pCodecCtx->codec_id is -2147483648.

I tried it with different videos and the libav library prints the correct codec
when the QVideoDecoder is created:
