  • Compile FFMPEG + x264 - undefined references

    18 juin 2013, par Tishu

    I have been trying to find a solution online for a couple of days with no luck. I am using Ubuntu and trying to compile the latest FFMPEG stable version (1.0.1) with x264 support. I made sure I uninstalled any existing x264 then I downloaded the latest x264 source and compiled it with the following config :

    ./configure --prefix=$PREFIX \
    
    --enable-shared \
    
    --enable-static \
    
    --disable-gpac \
    
    --extra-cflags=" -I$ARM_INC -fPIC -DANDROID -fpic -mthumb-interwork -ffunction-sections -funwind-tables -fno-short-enums -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__ -Wno-psabi -march=armv5te -msoft-float -mthumb -Os -fomit-frame-pointer -fno-strict-aliasing -finline-limit=64 -DANDROID -Wa,--noexecstack -MMD -MP " \
    
    --extra-ldflags=" -nostdlib -Bdynamic -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,nocopyreloc -Wl,-soname,/usr/lib/libz.so -Wl,-rpath-link=$ARM_LIB,-dynamic-linker=/system/bin/linker -L$ARM_LIB -lc -lm -ldl -lgcc" \
    
    --cross-prefix=${ARM_PRE}- \
    
    --disable-asm \
    
    --host=arm-linux \
    

    
    make clean
    
    make install

    All goes well, and I checked the installed version :

    x264 -V
    
    x264 0.129.x
    
    built on Dec 27 2012, gcc: 4.6.1
    
    configuration: --bit-depth=8 --chroma-format=all
    
    x264 license: GPL version 2 or later

    I then try to compile FFMPEG with the following options :

    ./configure --target-os=linux \
    
    --enable-libx264 \
    
    --enable-gpl \
    
    --prefix=$PREFIX \

    --enable-cross-compile \
    
    --extra-libs="-lgcc" \

    --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
    
    --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
    
    --nm=$PREBUILT/bin/arm-linux-androideabi-nm \
    
    --sysroot=$PLATFORM \

    The configure and make clean/make install work well, but when I try to create the .so file the following command fails :

    This fails with the following output :

    The x264 version it is looking for (129) is the one installed and compiled succesfully with —eanable-shared. Obviously all compiles fine when I do not include libx64.

    Question : How can I specify the include path for the last command ? I tried adding the path to $PATH and also adding this as an argument with no luck : -I/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/x264

    Thanks

  • Join two videos with unmatching audio streams in ffmpeg

    1er janvier 2013, par graup

    I already know how to concat multiple files using ffmpeg (e.g. like this).

    However, I have a specific problem. Due to an error while recording, the first video's video stream ends after about 14 minutes, while the audio stream is about 20 minutes long.
    The second video has complete video and audio streams.

    I hope this will make my situation clear :

    File 1:
    
V1: vvvvvvvvvvvvvvv________
    
A1: aaaaaaaaaaaaaaaaaaaaaaa
    

    
File 2:
    
V2: vvvvvvvvvvvv
    
A2: aaaaaaaaaaaa
    

    
Result after converting to MPEG-TS, concatting and encoding to mp4:
    
    vvvvvvvvvvvvvvvvvvvvvvvvvvv________
    
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
    

    
Expected:
    
    vvvvvvvvvvvvvvv________vvvvvvvvvvvv
    
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

    Anyone know how to do that ?
