Problems on compile decoder_ffmpeg extension

[lonewolf73]

Hello everyone,

I am trying to compile decoder_ffmpeg extension to obtain a libffmpegJNI.so in all architectures or even a libffmpegJNI.aar , to include in my android java project on Ubuntu 20.04LTS platform but I encounter some problems....

1. Platform : Ubuntu 20.04LTS
2. CMake : 3.31.4 (I even tried before with version 3.22.6)
3. I downloaded NDK r26b as suggested by README.md ( 26.1.10909125 ) and I downloaded and installed also the latest r27c ( 27.2.12479018 ) due I encountered during Android Studio "Make Module androidx.media3.lib-decoder-ffmpeg" a problem about iconv library not found...
4. I installed Opus 1.5.2 from opus-codec.org (I did ./configure , sudo make , sudo make install) to have latest libopus which could decode pure opus audio.
5. I installed first Ffmpeg following the readme and running git checkout release/6.0 (running ffmpeg -version I obtained a 6.0.2 version compiled by native gcc 9 of Ubuntu 9.4.0-1ubuntu1-20.04.2 ) but once encountering problems, maybe because CMake 3.31.4 is quite new, then I reinstalled latest Ffmpeg 7.1 (ffmpeg version N-118350-ge20ee9f9ae Copyright (c) 2000-2025 the FFmpeg developers) , both versions applying --enable-libopus parameter;
6. I have set Gradle 8.6 and AGP 8.4.2 on Android Studio
7. I set ANDROID_ABI to 28 so I set minSdk in gradle files to 28 because having most recent opus and ffmpeg should be more compatible with recent Android app versions
8. I set in build.gradle of ffmpeg extension as like :

}

In both cases with NDK r26b and r27c if I ran build_ffmpeg.sh ( sudo ./build_ffmpeg.sh "${FFMPEG_MODULE_PATH}" "${NDK_PATH}" "${HOST_PLATFORM}" "${ANDROID_ABI}" "${ENABLED_DECODERS[@]}" ) with those options (in particular for audio, I had to modify a bit the sh with COMMON_OPTIONS="${COMMON_OPTIONS} --enable-decoder=opus --enable-decoder=libopus --enable-decoder=pcm_alaw" ) due I included libopus in the linked ffmpeg .... it completed but it didn't produced any .so / .aar files... I encountered indeed :

WARNING: /home/user/DevTools/Android/ndk/26.1.10909125/toolchains/llvm/prebuilt/linux-x86_64/bin/x86_64-linux-android28-pkg-config not found, library detection may fail.
WARNING: Disabled libopus_decoder because not all dependencies are satisfied: libopus

so I think those two messages are just warnings but probably they are mandaroty.
I tried to create local toolchain using make_standalone_toolchain.py in ../26.1.10909125/build/tools but once created I searched inside for that pkg-config but wasn't present so for this part , shall I have to modify something somewhere to make it complete the build_ffmpeg.sh creating those .so / .aar file correctly?

Instead if I try to build using ./gradlew lib-decoder-ffmpeg:assembleRelease from media3 root directory ( it installed the gradle 8.6-all ) I get those errors:

BUILD FAILED in 38s

In this case , does maybe depend from the Gradle version itself and maybe shall I have to upgrade to Gradle 8.9 with AGP 8.7.x since they are anyway supported by Java 17 which is currently installed ?

Thanks in advance to all!

Instead if I try to build using ./gradlew lib-decoder-ffmpeg:assembleRelease from media3 root directory ( it installed the gradle 8.6-all ) I get those errors

These errors indicate the compileSdk in your project is set to less than 35. That's the reason it can't find the symbols.

I haven't looked into your ffmpeg build problems, but if your goal is to bundle support for OPUS specifically, I'd recommend to use the opus extension directly without going through ffmpeg. Our instructions also don't include downloading libopus specifically. Did you follow the steps in the README exactly and did they work?

[lonewolf73]

Hi @tonihei and everyone here ! Thanks for your answer...

• on Ubuntu Linux I installed Opus codec from opus-codec.org because I wanted to be sure to play pure opus (not the one incapsulated in ogg) .
• so I installed also Ffmpeg 7.1 (ffmpeg version N-118350-ge20ee9f9ae Copyright (c) 2000-2025 the FFmpeg developers) , applying --enable-libopus parameter;
• I checked build.gradles and in fact about previous errors it was about some gradle settings so I reached to compile everything in debug and release too.

Then I took those libffmpegJNI.so files for different architectures from /buildout/cxx/... and the lib_decoder_ffmpeg.aar file from /outputs/aar. I put them in my Java app, precisely:

in a jniLibs directory I put those directories with .so files and I added in build.gradle :

	sourceSets {
		main {
			jniLibs.srcDir('src/main/jniLibs')
		}
	}

then I added in MainActivity:

    static {
        try {
            System.loadLibrary("ffmpegjni");
        } catch (java.lang.UnsatisfiedLinkError e ) {
            Log.d("MainActivity", "Couldn't load external libraries");
            e.printStackTrace();
        }
    }

and I added also under /app/libs the lib-decoder-ffmpeg.aar and added in build.gradle

implementation fileTree(dir: 'libs', include: ['*.aar'], exclude: [])

and when I run on debug I see in Logcat :

Load /data/app/~~C9a-lbWrsGJvAQdfZlh1Jw==/xxxxxxxxxxx-AyASJ2U8W-WSouWGUsRj3Q==/base.apk!/lib/arm64-v8a/libffmpegjni.so using ns clns-4 from class loader (caller=/data/app/~~C9a-lbWrsGJvAQdfZlh1Jw==/xxxxxxxxx-AyASJ2U8W-WSouWGUsRj3Q==/base.apk!classes3.dex): ok
Loaded FfmpegVideoRenderer.
Loaded FfmpegAudioRenderer.

but it looks like that opus audio I am receiving through RTSP doesn't play even if I added in the code of exoplayer :

mediaItem = new MediaItem.Builder()
		.setUri(Uri.parse(url_nedia.toString()))
		.build();

defaultDataSource = new DefaultDataSource.Factory(
		this.getContext()
);

Uri uri = Uri.parse(url_nedia.toString());
rtspMediaSource = new RtspMediaSource.Factory()
		.setTimeoutMs(1000)
		.createMediaSource(MediaItem.fromUri(uri));

DefaultRenderersFactory defaultRenderersFactory = new DefaultRenderersFactory(this.getContext())
		.setExtensionRendererMode(DefaultRenderersFactory.EXTENSION_RENDERER_MODE_PREFER);

scaleAndRotateTransformation = new ScaleAndRotateTransformation.Builder().setRotationDegrees(parseFloat(degreesRTSP)).build();

customLoadControl = new DefaultLoadControl.Builder()
		.setBufferDurationsMs(32 * 1024, 64 * 1024, 1024, 1024)
		.build();

mediaPlayer = new ExoPlayer.Builder(this.getContext())
		.setLoadControl(customLoadControl)
		.setRenderersFactory(defaultRenderersFactory)
		.build();
playerView = getView().findViewById(R.id.playerView);
playerView.setPlayer(mediaPlayer);

mediaPlayer.addAnalyticsListener(new EventLogger());
mediaPlayer.setMediaItem(mediaItem);
mediaPlayer.setVideoScalingMode(C.VIDEO_SCALING_MODE_DEFAULT);
mediaPlayer.setVideoEffects(ImmutableList.of(scaleAndRotateTransformation));
mediaPlayer.prepare();
mediaPlayer.setPlayWhenReady(true);
mediaPlayer.play();

where if it uses defaultRenderersFactory it should prefer ffmpeg elaborating the opus decoder.... maybe is there a way to check if it is really elaborating the audio using the ffmpeg ?
Thanks in advance to all !!

[tonihei]

Just to reiterate - could you please follow the steps in the ffmpeg readme instead of wiring up the classes yourself via some aar logic? This will ensure the issue is not related to your special build setup.

maybe is there a way to check if it is really elaborating the audio using the ffmpeg ?

This should be visible in logcat or you attach a debugger to see which renderer class is used.

[lonewolf73]

hello again @tonihei , thanks for your answer .... you mean using build_ffmpeg.sh ?...
I thought even building using Android Studio could compile the same library.... .

anyway trying another test, in Logcat I see now :

Load /data/app/~~C9a-lbWrsGJvAQdfZlh1Jw==/xxxxxxxxxxx-AyASJ2U8W-WSouWGUsRj3Q==/base.apk!/lib/arm64-v8a/libffmpegjni.so using ns clns-4 from class loader (caller=/data/data/xxxxxxxxxx/code_cache/.overlay/base.apk/classes3.dex): ok

where should mean it would call the ffmpeg renderer... but once RTSP stream starts it returns instead :

should maybe that Caused by: java.lang.IndexOutOfBoundsException: Index: 0 means that audio packet is empty when it is playing audio with RTSP stream?
Eventually is there a way to ignore empty or late audio packet?.... I mean something like applying libvlc's parameters --drop-late-frames , --no-audio-time-stretch, --network-caching=1000 ?

Investigating more on logcat result, which I report here, I see there are probably some parameters that aren't recognized... eventually is there a way to pass some parameters to ffmpegdecoder / libopus?...

Thanks again to all!

Doing another little investigation , this time changing audio format to G711_alaw and debugging with Logcat I get this :

Audio sink error

which it doesn't make playing audio either, even in this decoding seems it is not using FFmpegAudioRenderer....
At least using G711_alaw audio I can see the video on surface, with opus I see black screen on surface instead...
Any suggestion?...

Thanks again!
Cheers!

Glad you solved the build problem.

Caused by: java.lang.IndexOutOfBoundsException: Index: 0 at java.util.Collections$EmptyList.get(Collections.java:4888)

This indicates the stream doesn't set up the initialization data correctly. This is different from your original issue though, so if you have reproduction steps and want us to have a look, please file a new issue and attach the media file causing the problem.

(I'll close this issue given the original problem was resolved)
