The .mp4 file spec allows for 3 different audio formats. AAC, MPEG1-Layer1 and
MPEG1-Layer2. AAC is by far the most often used audio codec.
I just made a quick video using each audio codec, and the only one that plays audio
in LC is the AAC version (MacOS, LC 9.5.0). To make sure you’re video is the right
format, download the sample stack in the bug report at
https://quality.livecode.com/show_bug.cgi?id=21278
<https://quality.livecode.com/show_bug.cgi?id=21278>. I know that video works,
at least on Mac.
On MacOS. Quicktime is the default player on the Mac still today, but it’s not
the same QuickTime from years ago that LC depended on. If “About QuickTime
Player” shows version 10.5, you’re on the new one. QuickTime Player 7 uses the
deprecated APIs.
I have QT 10.5 and it plays the video. Firefox does too. On Android, Chrome plays it. So it
looks like LC mobile player could be the problem.
I downloaded the file from your bug report, set a LC player to the filepath on my Mac, and got
the same empty black screen.
