FFMPEG 命令在 Android Q 中不起作用

Question

尝试使用此命令合并两个音频文件，但它在 Android 10.0(Q) 中不起作用，而 目标 sdk 29。但是，此命令完全适用于 targeting sdk 24 to 28.

我正在使用这个 FFMPEG 实现库 'nl.bravobit:android-ffmpeg:1.1.7'

"-y", "-i", path1, "-i", path2, "-filter_complex", "[0:0][1:0] amix=inputs=2:duration=longest", "-c:a", "libmp3lame", savedPath

my Error log:

给我解决上述问题。

Answer 1

因为这个库只支持最大 sdk 28 见下面 link:

https://github.com/bravobit/FFmpeg-Android/blob/master/android-ffmpeg/build.gradle

所以，在这个库中，SDK 29 中没有运行，因为 targetSdkVersion 28 和 compileSdkVersion 28。如果你想改变这件事，它会为你工作。我希望它能帮助你..！

Answer 2

现在，如果你们正在为 ANDROID Q 寻找 FFMPEG，这里是 link 使用下面的 FFMPEG 构建。将此添加到您的 app/build.gradle

最小 SDK 24

  dependencies {
        implementation 'com.arthenica:mobile-ffmpeg-full:4.3'
    }

最小 SDK 16

dependencies {
    implementation 'com.arthenica:mobile-ffmpeg-full:4.2.2.LTS'
}
