Pre-built FFmpegKit AAR for Android with hardware-accelerated H.264 and H.265 encoding via MediaCodec. LGPL licensed. 16KB page aligned for Android 15+.

FFmpegKit was retired in 2023. Existing community forks provide 16KB page alignment for Android 15 but ship with software-only encoders (mpeg4, no hardware acceleration).

This means every FFmpeg re-encode operation on Android (crop, resize, speed change, filters, format conversion) uses slow CPU-based encoding instead of the device's hardware encoder.

This project provides a pre-built AAR with h264_mediacodec and hevc_mediacodec enabled, so FFmpeg operations use the same hardware encoder that MediaCodec and Media3 Transformer use.

What changes for your app:

Use this if you:

• Previously used com.arthenica:ffmpeg-kit-* from Maven (now retired)
• Use com.moizhassan.ffmpeg:ffmpeg-kit-16kb but need hardware encoding
• Want FFmpeg video re-encoding to be fast instead of painfully slow
• Need LGPL-safe FFmpeg for a commercial Android app
• Target Android 15+ (requires 16KB page alignment)

Architectures: arm64-v8a, armeabi-v7a (covers all real Android devices)

No GPL components. Safe for closed-source commercial apps.

1. Download ffmpeg-kit-hardware.aar from the latest release.

2. Place in your libs/ folder and add to build.gradle.kts:

dependencies {
    implementation(files("libs/ffmpeg-kit-hardware.aar"))
    implementation("com.arthenica:smart-exception-java:0.2.1") // Required runtime dependency
}

3. Use hardware encoding:

import com.arthenica.ffmpegkit.FFmpegKit
import com.arthenica.ffmpegkit.ReturnCode

// H.265 hardware encoding
val session = FFmpegKit.execute("-i input.mp4 -c:v hevc_mediacodec -b:v 2M output.mp4")

if (ReturnCode.isSuccess(session.returnCode)) {
    // Done
}

The FFmpegKit API is identical to the original. Only the available encoders changed.
