test avutil FAILED


set environment var `QTAV_LOG=all` or C++ api `QtAV::setLogLevel(All)` to enable log.

For Player and QMLPlayer example app, choose log level `all` in config page.

Linking against FFmpeg 4.2 works as expected with no errors. Any hints?

Happening to me as well. Need to build QtAV linking to ffmpeg supporting decklink devices, but fails at the same point with the same error

You can make it build with a workaround: Add

#include <intsafe.h>

to the file libavutil/common.h, alongside the other includes.
