  • Static Compilation of FFmpeg with x264 support

    17 février 2014, par b1izzard

    Based on the Tutorial, I tried to build the latest FFmpeg binary with x264 support for Command line execution using Android-ndk-r9c.

    I had built the x264 using the below script :

     #!/bin/bash        
    

    

    
PREBUILT=/home/blizzard/bin/android-ndk-r9c/toolchains/arm-linux-androideabi-4.6/prebuilt
    
                PLATFORM=/home/blizzard/bin/android-ndk-r9c/platforms/android-9/arch-arm
    
                PREFIX=/home/blizzard/bin/android-ndk-r9c/sources/ffmpeg
    

    

    
            ./configure --prefix=$PREFIX \

            --sysroot=$PLATFORM
    

    
            make
    
            sudo make install
    
            sudo ldconfig

    For building FFmpeg I had used the below script :

     #!/bin/bash                    
    
              PLATFORM=/home/blizzard/bin/android-ndk-r9c/platforms/android-9/arch-arm

    Can anybody help me in building the latest version of FFmpeg or Can you share the latest FFMpeg binary for Android ?

  • Build FFmpeg for All Android architecture correctly

    22 octobre 2017, par fthopkins

    I built ffmpeg libraries for all android architecture. But some details are confusing my mind. First of all let me explain step by step how i built.

    • I downloaded latest version of libx264 from
      https://www.videolan.org/developers/x264.html
    • Created and run build_all.sh script (in x264 folder) for creating libs for (almost) all android platforms. Then i got android folder in x264 folder. e.g android/arm android/arm64 android/x86 android/x86_64 in x264 folder.
    • I download the ffmpeg3.3.4 from https://ffmpeg.org/download.html
    • I created 4 copies of ffmpeg3.3.4 folder. Named them with android architectures names.
      Like ffmpeg3.3.4-arm64 ffmpeg3.3.4-arm ffmpeg3.3.4-x86 ffmpeg3.3.4-x86_64
    • Created build_(architecture-name).sh for each platforms of android. Than move each one of 'named'.sh files to the named ffmpeg folders according to their architecture names.
      E.g build_android_x86.sh => ffmpeg3.3.4-x86

    • Moved all ffmpeg3.3.4-arm64 ffmpeg3.3.4-arm ffmpeg3.3.4-x86 ffmpeg3.3.4-x86_64 folders to the NDK_PATH (C:\Users\MyName\AppData\Local\Android\sdk\ndk-bundle)
    • Put x264 folder at same level of hierarchy with ffmpeg folders
      in (C:\Users\MyName\AppData\Local\Android\sdk\ndk-bundle)
    • Run each of build_android_x86.sh, build_android_x86_64.sh.. scripts one by one in their own ffmpeg folder. Then i got android folders in ffmpeg folders. (created android folders have library folders)
      e.g ffmpeg3.3.4-x86/android/x86/(bin,inlude,lib,share)

    • Created Android.mk files for all created android folders and moved each one of them to android/armName folder. e.g Android.mk => ffmpeg3.3.4-x86/android/x86/

    • Created videoEdit.c than run ndk-build build command.

    Built with no error. I can run ffmpeg commands but it takes too much time i think. E.g when i try to run hflip it flips the video with 15 seconds.

    Code example :

    JNIEXPORT jint JNICALL Java_com_name_app_library_VideoEditer_natives_VideoEditer_flipHorizontally
    
(JNIEnv *env, jclass someclass, jstring inputFile, jstring outFile) {
    

    
    int numberOfArgs = 14;
    

    
    char** arguments = calloc(numberOfArgs, sizeof(char*));
    
    const char *in, *out;
    

    
    in = (*env)->GetStringUTFChars(env, inputFile, 0);
    
    out = (*env)->GetStringUTFChars(env, outFile, 0);
    

    
    arguments[0] = "ffmpeg";
    
    arguments[1] = "-i";
    
    arguments[2] = in;
    
    arguments[3] = "-c:v";
    
    arguments[4] = "libx264";
    
    arguments[5] = "-preset";
    
    arguments[6] = "ultrafast";
    
    arguments[7] = "-threads";
    
    arguments[8] = "5";
    
    arguments[9] = "-c:a";
    
    arguments[10] = "copy";
    
    arguments[11] = "-vf";
    
    arguments[12] = "hflip";
    
    arguments[13] = out;
    

    
    int i;
    
    for (i = 0; i < numberOfArgs; i++) {
    
        log_message(arguments[i]);
    
    }
    
    log_message("Printed all");
    

    
    main(numberOfArgs, arguments);
    
    free(arguments);
    
    (*env)->ReleaseStringUTFChars(env, inputFile, in);
    
    (*env)->ReleaseStringUTFChars(env, outFile, out);
    

    
    return 0;
    
}

    Also another thing to confusing my mind is output of ./configure command.
    When i open the (e.g) ffmpeg-3.3.4-arm64-v8a folder and run ./configure command in terminal. Output says ARCH   x86 (generic). For all platform output is the same ARCH   x86 (generic). Commands run on emaulator very fast but very slow on real device.

    EDIT all of these steps made on ubuntu then moved all folders to the windows. So dont be confuse about paths.

    With all of these steps i want to ask is, is there anything wrong on my steps. Should i follow any other way or not ? Why the ffmpeg is running slower on real device. I guess building ffmpeg for android is bit messy and making wrong things is very easy. If you look my steps, questions and give me an advice, i will be much appreciated.

  • Translating Handbrake options to a FFMPEG command

    9 mai 2020, par Arif

    I want to convert a bunch of videos from x264 to x265, but I need to do so with ffmpeg in terminal because it's a remote server. These are my Handbrake options (listed items are ticked) :

    



    Summary tab

    



      

    • Web optimized

      • 


    • Align A/V Start

      • 


    



    Dimensions tab unchanged

    



    Filters tab

    



      

    • Sharpen - LapSharp, preset : Medium

      • 


    



    Video tab

    



      


    • Video codec - H.265 (x265)

      • 


    • Framerate (FPS) - 30 - Peak Framerate

      • 


    • Quality - Constant Quality - 28

      • 


    • Encoder preset - Medium

      • 


    • Encoder tune - None

      • 


    • Encoder profile - Auto

      • 


    



    Audio tab

    



      

    • Audio track - AAC, bitrate : 128

      • 


    



    Subtitles tab - No subtitles (remove if exists)

    



    This is the ffmpeg command that I've managed to compile so far :

    



    ffmpeg -i input.mp4 -c:v libx265 -crf 28 -c:a aac -b:a 128k -max_muxing_queue_size 400 -movflags +faststart output.mp4

    



    I have the following two questions :

    



      

    1. Does the ffmpeg command provided list all the options except the peak framerate, sharpening filter and removing subtitle ones ? How do I incorporate these three ?

      2. 


    2. Slightly unrelated, but does having -max_muxing_queue_size 400 negatively affect file size or video quality ? I've only included this because I'd ran into encoding errors in the past.

      3. 


    



    Thank you.

    



    My Handbrake log with the above options, if it helps :
