Seems like the ffmpeg we incldued doesn't have the aac encoder support enabled. I want to have a closer look at this to see if we can improve something for the future, thus it would be great if you can send your video file (or a small part of it) to forum (at) wikitude (dot) com. Thanks.
To solve this problem on your end please use a different audio encoding for your source video or if you feel comfortable with it replace the included ffmpeg with a custom version that includes the aac support.
Just let me know if you need any further help.

I'm trying to convert a transparent video using your command line instructions however when I run it I get this error - The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it. I know how to solve this with ffmpeg but passing in the same parameters doesn't work with your command line script. Any ideas as to how I can solve this? I am on a Mac if that helps.
