Re: How to extract a video clip...
Hi Paul, Your app doesn't have to install ffmpeg on the user's system - your app can run it from where it resides in your app's bundle. (Just reference it in your command line using its full path, not just 'ffmpeg'.)

Re: How to extract a video clip...
I was looking for some LiveCode lessons on how to use mergAV and there weren’t any. :-( Are there any good examples anywhere on how to use it?

Re: How to extract a video clip...
Thanks Martin, My issue with mergeAV is that it is macOS/iOS only and I need macOS and Windows, so I would have to find another solution for Windows and if I use ffmpeg for Windows, I might as well use it for macOS as well so the same command line works across platforms and I am just installing a different version of ffmpeg based upon OS. If mergeAV was macOS and Windows, I would definitely prioritize it over ffmpeg as a solution. I appreciate the suggestion though. I did not know mergeAV could create clips. -- Paul On 3/19/2022 3:50 PM, Martin Koob via use-livecode wrote: Hi Look up the mergAVVideoComposition commands etc. in the dictionary.

How to extract a video clip...
Hivemind, I have, in LiveCode, a list of media files (various formats mp4, mp3, etc.) and a list of start and end times for various clips from each of the files. A file may (and usually does) have several clips. Much to my disappointment, I can find NO way in LiveCode script to export a portion of the media from the start time to the end time. I hope with the revised media in LC10, this may get added! I CAN in LiveCode open the media in a Player object and play just the clip from startTime to endTime. Has anyone come up with a way, given just a file, start time, and end time, to output a new media file with just that clip? Perhaps a shell command to some already installed utility or a widget? I'd even consider installing a free command line utility IF it was relatively small (in terms of disk size) so I could packing in my app and have my app unpack it on startup (the first time). I need this capability on macOS and Windows at a minimum - other platforms are desirable, but a solution must be available for macOS and windows (need not be the SAME solution as long as the same result is achieved). Also, any solution needs to be local and not require a server based service. Thoughts?
