  • FFMpeg on Android, undefined references to libavcodec functions, although it is listed on command line

    1er juin 2016, par dimsuz

    I have a problem with unresolved references to ffmpeg’s libavcodec functions, so far failed to find the answer in other places (including my mind) :)

    Let me describe my setup - it takes space, but is really basic, it might be that I’m failing to see some error...

    I built an FFMPeg with ndk r5 toolchain, ffmpeg port I got from http://bambuser.com/opensource (as recommended in other questions here). It built fine, so I put several static libraries in my project like this :

    <project>/jni/bambuser_ffmpeg/libavcodec.a
    
<project>/jni/bambuser_ffmpeg/libavformat.a
    
<project>/jni/bambuser_ffmpeg/libavcore.a
    
<project>/jni/bambuser_ffmpeg/libavutil.a
    
</project></project></project></project>

    Next, I created an Android.mk in bambuser_ffmpeg folder to list these libs as a prebuilt ones :

    LOCAL_PATH := $(call my-dir)
    

    
include $(CLEAR_VARS)
    
LOCAL_MODULE := bambuser-libavcore
    
LOCAL_SRC_FILES := libavcore.a
    
include $(PREBUILT_STATIC_LIBRARY)
    

    
include $(CLEAR_VARS)
    
LOCAL_MODULE := bambuser-libavformat
    
LOCAL_SRC_FILES := libavformat.a
    
include $(PREBUILT_STATIC_LIBRARY)
    

    
(same for other two libs)

    Next, I have another module which references these libs in its Android.mk, sets up include paths, etc :

    LOCAL_PATH := $(call my-dir)
    

    
include $(CLEAR_VARS)
    

    
LOCAL_MODULE := ffmpegtest
    
LOCAL_STATIC_LIBRARIES := bambuser-libavcodec bambuser-libavcore bambuser-libavformat bambuser-libavutil
    
LOCAL_SRC_FILES := ffmpeg_test.cpp
    
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../bambuser_ffmpeg/include
    
LOCAL_LDLIBS    := -llog -lz
    

    
include $(BUILD_SHARED_LIBRARY)

    And finally I have my ffmpeg_test.cpp which is really basic, like this :

    #include 
    

    
extern "C" {
    
#include <libavcodec></libavcodec>avcodec.h>
    
#include <libavformat></libavformat>avformat.h>
    
}
    

    
extern "C" {
    
    JNIEXPORT jint JNICALL Java_com_the7art_ffmpegtest_PaintThread_testFFMpeg(JNIEnv* env, jobject obj, jstring fileName);
    
}
    

    
JNIEXPORT jint JNICALL Java_com_the7art_ffmpegtest_PaintThread_testFFMpeg(JNIEnv* env, jobject obj, jstring fileName)
    
{
    
    av_register_all();
    
    return 0;
    
}

    When I run ndk-build, it compiles fine, but when linking it prints an unresolved reference to almost every function in libavcodec. Looks like only this lib’s functions are failing to be located :

    /home/dimka/src/mobile/android/ffmpegtest/obj/local/armeabi/libavformat.a(allformats.o) :
    In function

    av_register_all':
     /home/dimka/work/suzy/tmp/ffmpeg-android/ffmpeg/libavformat/allformats.c:47:
     undefined reference to
     

    avcodec_register_all’
    /home/dimka/src/mobile/android/ffmpegtest/obj/local/armeabi/libavformat.a(utils.o) :
    In function

    parse_frame_rate':
     /home/dimka/work/suzy/tmp/ffmpeg-android/ffmpeg/libavformat/utils.c:3240:

    /home/dimka/src/mobile/android/ffmpegtest/obj/local/armeabi/libavformat.a(utils.o) :
    In function

    flush_packet_queue':
     /home/dimka/work/suzy/tmp/ffmpeg-android/ffmpeg/libavformat/utils.c:1277:
     undefined reference to
     

    av_free_packet’
    /home/dimka/work/suzy/tmp/ffmpeg-android/ffmpeg/libavformat/utils.c:1283 :
    undefined reference to

    av_free_packet'
     /home/dimka/src/mobile/android/ffmpegtest/obj/local/armeabi/libavformat.a(utils.o):
     In function

    get_audio_frame_size’ :
    /home/dimka/work/suzy/tmp/ffmpeg-android/ffmpeg/libavformat/utils.c:766 :
    undefined reference to

    av_get_bits_per_sample'
     /home/dimka/src/mobile/android/ffmpegtest/obj/local/armeabi/libavformat.a(utils.o):
     In function
     

    ff_interleave_add_packet’ :
    /home/dimka/work/suzy/tmp/ffmpeg-android/ffmpeg/libavformat/utils.c:2909 :
    undefined reference to `av_dup_packet’

    and so on...

    I fail to figure why this is happening. I tried running ndk-build V=1 to check the actual linking command, and libavcodec is sitting there perfectly right, like it should. All other ffmpeg libs are there too.

    Any hints ?

  • Issue #2 when compiling Xuggler for Raspberry pi with libx264

    2 août 2014, par Ashish Sharma

    I am trying to compile Xuggler for Raspberry Pi(Running on Debian OS aka Raspbian),

    I followed the ’Basic Build Instructions’ available here for compiling Xuggler.

    After I successfully installed all the prerequisites and set the correct paths, I ran the following command :

    ant run-tests

    After sometime I am facing the following error and the ant build fails at libx264 :
