Any thoughts?

Same thing: [iso file] Unknown box type gmhd [iso file] Unknown box type gmin [ISO file] dataReferenceIndex set to 0 in sample entry, overriding to 1

That gave me: [iso file] Unknown box type gmhd [iso file] Unknown box type gmin [ISO file] dataReferenceIndex set to 0 in sample entry, overriding to 1

OK, I did what you said, but it still fails!

I'll try that shortly, thanks! Is this something you might consider fixing/adding in an update? Thanks again

Any ideas? Thanks

That gave me the following... ffmpeg version 4.0.2 Copyright (c) 2000-2018 the FFmpeg developers built with gcc 7.3.1 (GCC) 20180722 configuration: --disable-static --enable-shared --enable-gpl --enable-version3 --enable-sdl2 --enable-bzlib --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libfreetype --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr...

That was everything, I can take a screenshot if that would help? Is there any other info I can help you with?
