After installing via SPM I get the following error upon the first build:

'sortedKeys' is only available in iOS 11.0 or newer

in the file DumpHelpGenerator.swift in line 30.

Do you have plans to support progress callbacks for it?

When I set enable for lib fdk-aac, x264 or lame, after downloading library's source. It showed error
"Unknown option "--host=aarch64-apple-darwin"."
then exit.

I run on Big Sur.

I've run the command swift run ffmpeg-ios but found the error above.

In an open source project, we have this example app that depends on FFmpeg-iOS (see here). First, thanks a lot for that 🙂.

When going into the "distribution" stage of the app, the following error occurs:

2021-04-13 19:54:30 +0000  Assertion failed: Expected 1 archs in otool output:

Would you have an idea what that means? We thought that there were maybe non-arm64 symbols in libavcodec.a, but we only found arm64 symbols there...

We need to upload the encoded video to be displayed in a web browser, so we're trying to encode it to H.264. Here's our code:

let result = ffmpeg(["ffmpeg",
                             "-hide_banner", "-loglevel", "error", /// quiet
                             "-i", inPath.absoluteString, /// input file
                             "-filter:v", "scale=\(scale)", /// scale to the desired size
                             "-c:v", "libx264", /// use H.264 codec
                             "-c:a", "copy", /// copy audio stream "as is"
                             outPath.absoluteString])

However, we get the error message:

�[1;35m[vost#0:0 @ 0x117d857a0] �[0m�[4;31mUnknown encoder 'libx264'
�[0m

Is there another way to achieve this?

Hi man, great work. Thanks for your time.

I have some issue when I tray to import avformat I get this error "No such module 'avformat'".
Do I missed some steps?

I've followed following steps:

git clone https://github.com/kewlbear/FFmpeg-iOS.git
cd FFmpeg-iOS

how to cancel current task?

let result = ffmpeg(["ffmpeg", "-i", source.path, destination])

encountered an error while I was converting .m4a to .mp3:

I read in the license terms of LGPL that ffmpeg can be used in a commercial app (without opening up its source code), if the library has been dynamically linked.

ChatGPT told me that this is the case if the library has been added as a .dylib.

Is this the case for this package?

error: target at '..../SourcePackages/checkouts/FFmpeg-iOS/Sources/Tool' contains mixed language source files; feature not supported

Running into a mixed language in target error, any idea how to fix? At least locally?

This occurs after a certain stage when I run swift run ffmpeg-ios
