 using the code
 {{{
 const AVOutputFormat* ofmt = av_guess_format("MP4", nullptr, nullptr);
 int supported = avformat_query_codec(ofmt, AV_CODEC_ID_VORBIS,
 FF_COMPLIANCE_STRICT);
 }}}
 I find the returned value of 1 surprising, which would be indicating
 support. Actually the result is always 1 no matter which compliance level
 is provided. And testing a few other codecs I found the same situation.
 For example AV_CODEC_AV1 also always checks out as beeing supported, which
 I expected not to be at least for more strict compliance levels??
