• Mute the video stream and overlay the stream with a picture using ffmpeg

  20 novembre 2020, par cold_fire99

  I reveive a stream from OBS and want to mute it and overlay it with a partly transparent picture (png).

  


  Here is the command that I use (insite rtmp module of nginx), but this does not deliver an correct output stream :

  


  exec ffmpeg -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=48000 -i rtmp ://localhost/live/$(name) -i /var/www/stream/facebook-overlay.png -filter_complex "[1:v][2:v] overlay=0:0" -pix_fmt yuv420p -c:a aac -map 0:a -ar 48000 -shortest -f flv rtmp ://127.0.0.1:1936/rtmp/$(name)

  


  Any ideas how this works to overlay with these 3 input streams ?

• RN 0.74.7 can't find repo for ffmpeg-kit-react-native 6.0.2

  30 avril, par user938363

  My React Native 0.74.7 (on MacOS) app has hard time to find the ffmpeg-kit-react-native repo when run-android. It constantly complains no repo found on maven. Here is the error when react-native run-android :

  


  * What went wrong:
Could not determine the dependencies of task ':app:processDebugResources'.
> Could not resolve all task dependencies for configuration ':app:debugRuntimeClasspath'.
   > Could not find com.arthenica:ffmpeg-kit-full-gpl:6.0.
     Searched in the following locations:
       - https://oss.sonatype.org/content/repositories/snapshots/com/arthenica/ffmpeg-kit-full-gpl/6.0/ffmpeg-kit-full-gpl-6.0.pom
       - https://repo.maven.apache.org/maven2/com/arthenica/ffmpeg-kit-full-gpl/6.0/ffmpeg-kit-full-gpl-6.0.pom
       - file:/Users/macbook/Documents/code/js/VmonFront/node_modules/jsc-android/dist/com/arthenica/ffmpeg-kit-full-gpl/6.0/ffmpeg-kit-full-gpl-6.0.pom
       - https://dl.google.com/dl/android/maven2/com/arthenica/ffmpeg-kit-full-gpl/6.0/ffmpeg-kit-full-gpl-6.0.pom
       - https://www.jitpack.io/com/arthenica/ffmpeg-kit-full-gpl/6.0/ffmpeg-kit-full-gpl-6.0.pom
     Required by:
         project :app > project :ffmpeg-kit-react-native


  


  In android/build.gradle, the repo was specified :

  


  buildscript {
    ext {
        buildToolsVersion = "34.0.0"
        minSdkVersion = 23
        compileSdkVersion = 34
        targetSdkVersion = 34
        ndkVersion = "26.1.10909125"
        kotlinVersion = "1.9.22"

        ffmpegKitPackage = "full-gpl"
    }

    repositories {
        google()
        mavenCentral()
        maven { url "https://jitpack.io" }
        // You can comment out the below line if it causes issues:
        maven { url 'https://maven.arthenica.com/public/' } //<<<===repo here
    }

    dependencies {
        classpath("com.android.tools.build:gradle")
        classpath("com.facebook.react:react-native-gradle-plugin")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin")
    }
}


apply plugin: "com.facebook.react.rootproject"


  


  Also the following code is added to android/app/build.gradle :

  


  // 🔥 Add this block to override the wrong version in ffmpeg's gradle.properties
configurations.all {
    resolutionStrategy {
        force "com.arthenica:ffmpeg-kit-https:6.0". //<<<===6.0.2 or 6 didn't work
        force "com.arthenica:ffmpeg-kit-full-gpl:6.0" // Include if using other packages
    }
}


  


  The problem seems to be with RN 0.74.7 only, as my RN 0.78.0 with ffmpeg-kit-react-native installed was able to download full-gpl version and installed successfully. What is missing here to install ffmpeg-kit on RN 0.74.7 ?
