Note that any hevc file will produce this error. hdr10tags-stream.mp4 is available here: https://storage.googleapis.com/ffms2tests/hdr10tags-stream.mp4 Would it be possible to disable this hardware decoder? -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
