Hi jbv

Here’s a tool that can help you create what you’re describing.

 I’ve done some research, and it looks interesting to create a LiveCode

 Api (xAPI).
 
 There are some free servers to use, and hosting our own community server 
 would also be readable. I feel that any LiveCode developers with a focus 
 on education would benefit from this library.
 
 Do we have a Zoom today Brian?

Re: Video format for mobile

[Bryan Anderson via use-livecode]

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 
. 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.

Re: Apple Video Foundation (AVF) and .mpg files

[Bryan Anderson via use-livecode]

ffmpeg is your friend!

Here’s what you need…
https://www.ffmpeg.org/ffprobe.html  

ffprobe -show_format filename.mpg 
...will give you human readable output with lots of useful information 
including the codec used.

If you want to drill down further…
ffprobe -show_entries stream=format_name filename.mpg
… will give you a line that will look something like…
Stream #0:0: Video: mpeg1video, yuv420p(tv), 320x240 [SAR 1:1 DAR 4:3], 320 
kb/s, 29.97 fps, 29.97 tbr, 1200k tbn, 29.97 tbc


If the video file you want LiveCode to work with is not supported, you can use 
ffmpeg to convert it to something else with ffmpeg
https://www.ffmpeg.org/ffmpeg.html 

You can convert just about anything to anything else. It’s really powerful.
ffmpeg has a -progess switch that can be used to give a nice progress bar in 
LiveCode during conversion.

Resetting waitDepth

[Bryan Anderson via use-livecode]

Is there any way to clear out waiting commands…similar to the "cancel
messageQueueID” for messages queued up using the “send” command? I’ve
looked high and low…

see “the waitDepth”

Thanks!
