I can confirm this works and builds successfully with Mac Catalina + XCode 11.2.1.

Trying to run the app, it generates the following error.

@Zen-CODE sorry I never mentioned this - when I was fighting with Xcode 12, and I went back to Xcode 11 to get things working, I had to add "libiconv.tbd" (or something like that) to the list of "Frameworks" in the Xcode project - I did it in the GUI but I assume some automagic fix could be made in the Xcode project file?

EDIT: FWIW it works in the simulator, but I didn't have the opportunity to test on real device yet (or rather it crashes but I don't have logs so I don't know why).

@Zen-CODE I have an upcoming PR to get this one working on Xcode 12.2 + a demo app, meanwhile can you please upgrade also hostopenssl to 1.1.1g?

[Zen-CODE]

You don't want to do that as part of this PR? Is there a reason for that?

For the hostopenssl upgrade part it absolutely makes sense to have that in this PR.�

The fixes that I made on the other upcoming PR are quite unrelated but at the same time also fixes an issue that was triggered while testing this PR, so I prefer to hold it separate for future maintenance.

[Zen-CODE]

Sure, makes sense. I'll prep and test that shortly...

[Zen-CODE]

@misl6 Merged those changes so you are unblocked asap. Let's hope it works 👍

@Zen-CODE

With all the recent changes + #571 you should be able to run on both Simulator and real device a videoplayer demo app that uses ffmpeg4.3.1 + openssl1.1.1g on top of Xcode 12.2

Just for reference, I created a simple demo app for demonstrating / testing it.
https://gist.github.com/misl6/a6752029e6589c1e4f5a0d9ab4529907

I'm able to run it on Simulator + a real device with the latest iOS version.

[Zen-CODE]

It still gives an "OpenSSL not found" when building with the existing ffmpeg (Testing on XCode 12.1 first). Please could you change the version in the ffmpeg recipe to "n4.3.1" to fix that in this PR?

Thanks for creating an app to test with, but I can't get it running for love or money. It builds, but gives me the attached permissions error when I try to run. Lots of googling + experiment get me nowhere...Building touchtracer works fine though, and it does build so it's still an improvement as the older ffmpeg does not! And I can't see that these changes would cause this.

[dotrichard]

Can confirm it fixes the build issues Xcode 11.2.1/Catalina
