Mobile-ffmpeg: unknown encoder libx264 when running sample test app and making custom build

[tianxind]

Description
We are trying to run the test-app and make our custom build with the latest 4.2 LTS release, and with x264 encoder. Everything works fine except that every time we try to call anything in x264, or choose to encode the video with x264 in the sample app, it displays the error message:

Unknown encoder 'libx264'

Command we run to build mobile-ffmpeg libraries: ./android.sh --lts --enable-gpl --enable-x264
Command we run to build the sample app: ./gradlew :test-app:assembleDebug

Environment

• Platform: Android
• Architecture: arm-v7a
• Version (if applicable) v4.2.LTS
• Android Studio version (if applicable) 3.1.4
• Android NDK version (if applicable) r19c

Any help would be greatly appreciated!

Can I get answers to these questions?

1. What are the dependencies in your build.gradle file?
2. Which source branch do you use?
3. What version is printed in the mobile-ffmpeg init string?

Loading mobile-ffmpeg.
Loaded mobile-ffmpeg-<version>.

Hi Tanersener,

Thank you so much for your quick response! Here are the answers to your questions:

1. We are building a react-native app with the prebuilt .so and .a libraries. Here are the dependencies:

dependencies {
    implementation 'com.facebook.android:facebook-android-sdk:[4,5)'
    implementation project(':react-native-fbsdk')
    implementation project(':react-native-vector-icons')
    implementation project(':react-native-linear-gradient')
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    androidTestImplementation('com.android.support.test:runner:0.5') {
        exclude module: 'support-annotations'
    }
    worldImplementation 'com.google.firebase:firebase-core:11.8.0'
    worldImplementation 'com.google.firebase:firebase-messaging:11.8.0'
    implementation 'com.crashlytics.sdk.android:crashlytics:2.9.1'
    implementation 'com.google.firebase:firebase-ads:11.8.0'
    implementation 'com.squareup.okhttp3:okhttp:3.10.0'
    implementation 'com.facebook.react:react-native:+'
    implementation "com.android.support:recyclerview-v7:27.0.2"
    implementation 'org.apache.directory.studio:org.apache.commons.io:2.4'
    implementation 'com.squareup.picasso:picasso:2.5.2'
}

1. Source branch is master (commit 5f9813877fca1b22ab0f4f7987737f3a97de7467). Basically the latest 4.2 LTS release

@tanersener I am facing the same issue with x264 encode. Is there any solution for 4.2 LTS release?

LTS releases include LTS postfix in the version string. This log shows that you are depending full package of v4.2 not your local build.

Please check your dependencies.

@adapana video package does not include x264 library. Please refer to Using section of README to see which packages include x264.

Hi Tanersener,

How do you link the test-app against LTS? Should I do anything else other than first running:
./android.sh --lts --enable-gpl --enable-x264
and then run: ./gradlew :test-app:assembleDebug
Anything else I am missing here?

The gradle dependencies I posted is for our own react-native app. We just add those prebuilt .so and .a libraries to our own app through CMakeList. We are not using the .aar files. That's why you don't see the mobile-ffmpeg dependencies.

Thank you!

test-app is used to test both local builds and published releases. mobile-ffmpeg dependency used in test-app/build.gradle defines which one is tested.

If you look inside test-app/build.gradle at commit 5f9813877fca1b22ab0f4f7987737f3a97de7467 you can see the following dependency, which means that mobile-ffmpeg-full-4.2 is tested at that point.

implementation 'com.arthenica:mobile-ffmpeg-full:4.2'

To test your local build, please use the following dependency.

implementation project(':app')

[seema-spark6]

I am running this command in sample test-app itself:

    String command="-i "+video1 + " -i " + video2 +" -filter_complex \"[1:v]setpts=PTS-10/TB[a]" + ";"+
            "[0:v][a]overlay=enable=gte(t\\,5):shortest=1[out]\" " + ""+
            "-map [out] -map 0:a:0? -c:v libx264 -crf 18 -pix_fmt yuv420p -c:a copy "+ videoOut;

Getting unknown encoder libx264.

Any idea what is the issue in command.

[seema-spark6]

@tanersener Your help will be highly appreciated. I am totally stuck in test-app itself after i added my own command.

[tanersener]

@seema-spark6 Which mobile-ffmpeg package do you use? x264 is included in only GPL licensed mobile-ffmpeg packages. See README.

[enigmablue]

had an issue here also with no encoder, and solved by updating to min-gpl.

[Mr-Ramzan]

@enigmablue please can you explain how one can update to min-gpl
The Steps please

[enigmablue]

for ios

you have to add it to the pod react-native-ffmpeg/[insert package].
Example for min-gps-lts below:

pod 'react-native-ffmpeg/min-gpl-lts', :podspec => '../node_modules/react-native-ffmpeg/react-native-ffmpeg.podspec'

For android its in build.gradle

buildscript {
    ext {
        ...
        reactNativeFFmpegPackage = "min-gpl-lts"
    }

[Mr-Ramzan]

@enigmablue Thank you

[usmanrana07]

@enigmablue can you please elaborate a bit more about usage of this?

[Mr-Ramzan]

@enigmablue can you please elaborate a bit more about usage of this?

If you are looking for android Dependency

implementation 'com.arthenica:mobile-ffmpeg-full-gpl:4.4

Update this"mobile-ffmpeg-full-gpl " part according to requirements See Table On main project page

[gprashanthkumar]

Hi Peers,
If anyone is getting an unknown encoder/codec "libx264" error.
please use min-gpl:x.xx
e.g implementation 'com.arthenica:mobile-ffmpeg-min-gpl:4.4'
It fixed for me.
