  • php_ffmpeg some error and solutions

    26 mars 2018, par sonam Sharma

    I have successfully installed php_ffmpeg in my new project with the help of a guy on stackoverflow.com.
    I can do the basic jobs like extracting a frame out of a video
    but when I try to convert the video to another format I get this error :

    Fatal error : Uncaught exception ’Alchemy\BinaryDriver\Exception\ExecutionFailureException’
    with message ’ffprobe failed to execute command "C :\ffmpeg\bin\ffprobe.EXE"
    "sample3.mp4" "-show_streams" "-print_format" "json"’ in

    C :\wamp\www\raidpipe\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe.php on line 244

    I have used this code in my test page :

     <?php
    
 require 'vendor/autoload.php';
    
 $ffmpeg = FFMpeg\FFMpeg::create();
    
 $video = $ffmpeg->open('test/sample3.mp4');
    
 $video
    
->filters()
    
->resize(new FFMpeg\Coordinate\Dimension(320, 240))
    
->synchronize();
    
  $video
    
->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(19))
    
->save('test/clip/frame123.jpg');
    
  $video
    
->save(new FFMpeg\Format\Video\X264(), 'export-x264.mp4')
    
->save(new FFMpeg\Format\Video\WMV(), 'export-wmv.wmv')
    
->save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');
    
 ?>

    When I run this code it gives me the frame without any error

     require 'vendor/autoload.php';
    
  $ffmpeg = FFMpeg\FFMpeg::create();
    
  $video = $ffmpeg->open('test/sample3.mp4');
    
  $video
    
->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(19))
    
->save('test/clip/frame123.jpg');

    Please suggest me a way to convert the video by using the php_ffmpeg
    i need the video to be converted to some basic formats which can be supported by all the browsers and also please let me know is it a good practice to use exc (execute) in php ??

  • how to install arm64 ffmpeg on x86 ubuntu

    22 avril 2023, par rat star

    I've tried to install arm ffmpeg on my Ubuntu x86 because I need x86 environment to develop and run on my aarch64 device. So I installed x264 and use these codes :

    


    ./configure --enable-shared --enable-pic --enable-static --disable-x86asm --cross-prefix=aarch64-linux-gnu- --enable-cross-compile --arch=aarch64 --target-os=linux --enable-libx264 --enable-gpl --prefix=${THIRDPART_PATH} --extra-cflags=-I/usr/local/include --extra-ldflags=-L/usr/local/lib
make -j8
make install


    


    howerver, it succeeded in configure after I installed pkg-config-aarch64-linux-gnu and export path like

    


    export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"


    


    but when I functioned "make -j8", it failed and returned error message below :

    


    /usr/lib/gcc-cross/aarch64-linux-gnu/7/../../../../aarch64-linux-gnu/bin/ld: skipping incompatible /usr/local/lib/libx264.so when searching for -lx264

    How can I solve that ?

    


    I've depicted all above
