I have a problem building a custom version of FFMPEG but I have no idea of the correct forum in which to ask for help with it. Any suggestions?
I might add that I am building it under Windows 7 using MinGW and Msys2 environments.
- I would love to change the world, but they won’t give me the source code.

I would suspect whichever language it was written in would be the most appropriate forum.

It's in C but that isn't really the problem. I am getting a weird error message during the MAKE part of the build. I am familiar with Windows programming but haven't done any real Linux style stuff since I used UNIX in 1984!

When I do the make command it goes off and does a lot of stuff but then comes back (with an imagined screeching halt) to:
AR libavformat/libavformat.a
C:\Program Files\mingw-w64\x86_64-4.9.2-win32-seh-rt_v4-rev2\mingw64\bin\ar.exe: libavformat: Permission denied
library.mak:39: recipe for target 'libavformat/libavformat.a' failed
make: *** [libavformat/libavformat.a] Error 1 I am doing this using Msys2 under MinGw on Windows 7.
- I would love to change the world, but they won’t give me the source code.

Usually, yes. However, I theoretically have permission to everything everywhere on all my machines so this doesn't really help me!

UAC can be a fickle beast on Windows 7.
Unless you're logged in under the local Administrator account, you'd be surprised what things you can get blocked from doing (even running under an account in the administrators group.)
I'm going to assume you're invoking make from the command line? Try running your command prompt as administrator first (if you haven't already.) If that fails, try setting the properties on all of the utilized exes to always run as admin. If that still fails, I'd try turning off UAC entirely (I usually use TweakUAC, but last I looked I think it moved to either a paid model, or ad-ware )
I know many people advise against disabling UAC completely, but I find it gets in the way more often than it helps...

Years ago I had to compile the FFMPEG stuff using Cygwin rather than Mingw32. Not sure if that's relevant anymore though.

Cygwin is alive and well and I nearly chose to use it instead of MinGW - I might have to try it yet.

Sure, but you're not going to find many MAKE folks in the ASP.NET forum for instance. Your best bet is the language it's written in still.

If you have problems with Make, I suggest that you post in the exorcism forum!!!
I'd rather be phishing!

Or QA - it's not "limited" to a single topic in the same way that the forums are.

It's more likely to be related to the program than the language, so how about an FFMPEG forum[^]?

I am a first time application developer. It is directed towards the disabled community and it is an application for locating accessible venues. When developing the application will it automatically be offered internationally through the App Store as well as Google Play? If not, is the international market suitable for my application?

Just a thought: have you tried to contact the AppStore/Google and ask them or checked their FAQ? (I'm sure someone will be along soon that may have an answer here).

How could anyone who has not tried it possibly know that?

Smells like spam to me

No, I am definitely not a spambot. Nor, was I hired by some company to spam these message boards. If that were the case, these boards would already be filled up.

With a title like "International Distribution" (think of the "legal highs" or "herbal viagra" spam emails that we all see far too often) and a poorly constructed message..

All that was missing was a link to some site or other, and it was only that which stopped me from flagging the message as spam
You're probably better off posting your message in the Q&A section, but include some more detail like:
- What are you actually developing? A mobile app? A website?
- What technologies you're using? iOS, Java, HTML/JS, Xamarin, Cordova, etc?
- Who is your intended user and how do you want them to get to your app?
Help the people here to help you!

Oh, I don't think so...you'd be surprised how many spammers we get, and how quickly they are disposed of!
