Re: {OT} Are there any ffmpeg "experts" on this list?
Hi Mark Yes mergAV can be used concatenate videos, resize them, layer them and then export them to a video file. I wrote an app that did this a while ago on LiveCode 6.7.3. I haven’t tried using mergAV on LC 9.x. It would be nice if there was a set of common commands that could be used to do video editing on either Mac or Windows, just like player object does with video playback. Probably not a high demand for that though to make it cost effective.

FWIW, I *think* mergAV can do similar things on macOS* to the mediafoundation external on Windows - although the APIs, while similar, do require different code. However, if you are using ffmpeg for things other than concatenating tracks/movies (i.e. the features those libraries provide) then the separate code needed wouldn't be worth it to save inclusion of ffmpeg.

Panos, Thank you! I was unaware of the mediaFoundation library - I had thought that we'd not see support under LiveCode 10 switches from DirectShow to MediaFoundation. That said, our application is macOS and Windows and the appeal of ffmpeg via shell is that the same code will work across platforms for us. Still, for other projects, I'm very happy to have been made aware of the mediaFoundation library!

Re: {OT} Are there any ffmpeg "experts" on this list?
In one of my projects i do use ffmpeg for some audio conversion and id3 tag handling. For me the tool ff-Works (https://ffworks.net) helped me a lot. Normally its a GUI for ffmpeg, but the good thing is the user is also able to see the command line that was used for a task. So in case no one other jumps in and if you are on Mac maybe this tool is also of help for you, i Regards, Matthias > Am 24.06.2022 um 17:07 schrieb Paul Dupuis via use-livecode > : > > I am doing some work with Livecode script constructing calls (via shell()) to > ffmpeg to perform some video/audio concatenation. > > I have barely learned a tiny bit of ffmpeg and and wondering if there are any > people proficient with ffmpeg wh might be interesting in a small bit of paid > consulting to help with ffmpeg command line syntax for various operations? > > If interested, please email me directly. > > > ___ > use-livecode mailing list > use-livecode@lists.runrev.com > Please visit this url to subscribe, unsubscribe and manage your subscription > preferences: > http://lists.runrev.com/mailman/listinfo/use-livecode ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Hello Paul Not a ffmpeg expert, but have you seen the mediaFoundation library? See the dictionary entry for "mediaFoundationTranscode" - it has a detailed example for concatenating 2 media files.
