Android Java — Using and building FFMPEG library in Android Studio(Cmake)
12 septembre 2017, par y3k00000As title, I’m trying to use the ffmpeg source code as library in Android Studio on Ubuntu Linux, but meeting some trouble in compilation stage. I think I must be missing some compile option but having no idea what I miss, can somebody lend a hand ?
My codes & settings are below :
A simple auto-generated .cpp
#include
#include <string>
#include "libavcodec/aacenc.h"
extern "C"
JNIEXPORT jstring JNICALL
Java_y3k_testffmpegnative_MainActivity_stringFromJNI(
JNIEnv *env,
jobject /* this */) {
std::string hello = "Hello from C++";
return env->NewStringUTF(hello.c_str());
}
AACEncContext * aacEncContext; // Just trying by adding this.
</string>I’ve tried these Gradle setting and it didn’t help :
android {
....
externalNativeBuild {
cmake {
arguments "-DANDROID_TOOLCHAIN=clang"
cFlags "-std=c99"
cppFlags "-frtti","-fexceptions"
}
}
}
....CMakeLists.txt

build_oneBy tracing the errors I found these lines :
in float_dsp.h, fixed_dsp.h :

#define av_restrict restrictin aac.h :
....
struct AACContext {
AVClass *class;
....in mpeg4audio.h :
extern av_export const int avpriv_mpeg4audio_sample_rates[16];So I’m guessing it’s because the compiler misrecognized the C code as C++, I tried adding these :
arguments "-DANDROID_TOOLCHAIN=clang"
cFlags "-std=c99"to my build.gradle but didn’t help. Having no idea where to move on. :(
I’m using the latest stable version of Android Studio on Ubuntu desktop. Please don’t be hesitate to ask if any extra information is required.
Also I’ve been tried edit my native-lib.cpp into .c (Surely with the code contents changed), but wasn’t working either.
Appreciate for any help.

Unknown encoder 'libx265' when using command in Android studio java
26 mai 2023, par Entwickler WitzeI try to compress a video using a library and running a FFmpeg command in my android app written in java (although the library is in Kotlin)
I manage to do basic operations but the current one I am going to show you will always fail with the following error code : Unknown encoder 'libx265'


The library expects the input to be a String[] and I assume that there is something going wrong but I cannot find what exactly.


the command line


val query:Array<string> = arrayOf("-i", videoPath , "-c:v" , "libx265" ,"preset", "fast", "-crf", "30", "-tag:v", "hvc1", "-c:a", "eac3", "-b:a", "224k" , "$videoPath.mp4");
</string>

the entire code


fun videoCompress(videoPath: String) {
 val query:Array<string> = arrayOf("-i", videoPath , "-c:v" , "libx265" ,"-preset", "fast", "-crf", "30", "-tag:v", "hvc1", "-c:a", "eac3", "-b:a", "224k" , "$videoPath.mp4");

 CallBackOfQuery().callQuery(query, object : FFmpegCallBack {
 override fun statisticsProcess(statistics: Statistics) {
 Log.i("FFMPEG LOG : ", statistics.videoFrameNumber.toString())
 }

 override fun process(logMessage: LogMessage) {
 Log.i("FFMPEG LOG : ", logMessage.text)
 }

 override fun success() {
 Log.d("yyyy", "success: ")
 }

 override fun cancel() {
 }

 override fun failed() {
 }
 })
}
</string>



what I added to my build.gradle file


implementation 'com.github.SimformSolutionsPvtLtd:SSffmpegVideoOperation:1.0.8'


the result (exact)


Unknown encoder 'libx265'
