• how to compress and change video format by ffmpeg

  29 juillet 2015, par sonam Sharma

  Hello all i have successfully installed ffmpeg into my server for using it for my video hosting site.

  Now i am having a small issue please help me with this, i am really stuck here ...

  I am uploading a video bya form which is like

    <form action="somepage.php" method="post">
  
    <input type="file" />
  
    </form>

  And on the action somepage.php i have something like this

    <?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/frame12223.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');
  
  
  
   ?>

  I know the action page is wrong but i have no idea what to put there i need to get a frame out of that video after 13 seconds and convert and compress the video.

  Please just help me with some sample codes or any link please ..

• FFMPEG with SoX : configure : error : cannot find ffmpeg

  17 janvier 2014, par Alberto Megía

  So I am trying to install in my Ubuntu Desktop 12.04 SoX with FFMPEG support for m4a files.

  I have followed this instructions to install FFMPEG, installing only certain encoders. Finally, this is my set up :

  ffmpeg version git-2014-01-17-3ca7085 Copyright (c) 2000-2014 the FFmpeg developers
  
    built on Jan 17 2014 12:36:01 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5)
  
    configuration: --prefix=~/ffmpeg_build --extra-cflags=-I~/ffmpeg_build/include --extra-ldflags=-L~/ffmpeg_build/lib --bindir=~/bin --extra-libs=-ldl --enable-gpl --enable-libass --enable-libfdk-aac --enable-libmp3lame --enable-nonfree
  
    libavutil      52. 62.100 / 52. 62.100
  
    libavcodec     55. 48.101 / 55. 48.101
  
    libavformat    55. 23.103 / 55. 23.103
  
    libavdevice    55.  5.102 / 55.  5.102

    libpostproc    52.  3.100 / 52.  3.100
  
  Hyper fast Audio and Video encoder

  Then, I wget SoX 14.4.1 version and try to configure with FFMPEG support like this :

  ./configure --with-ffmpeg

  But I get this error :

  checking for FFMPEG... no
  
  checking libavformat/avformat.h usability... no
  
  checking libavformat/avformat.h presence... no
  
  checking for libavformat/avformat.h... no
  
  checking ffmpeg/avformat.h usability... no
  
  checking ffmpeg/avformat.h presence... no
  
  checking for ffmpeg/avformat.h... no
  
  configure: error: in `~/sox-14.4.1':
  
  configure: error: cannot find ffmpeg
  
  See `config.log' for more details

  So I try to set PKG_CONFIG_PATH environment variable :

  PKG_CONFIG_PATH=~/ffmpeg_build/lib/pkgconfig
  
  ./configure --with-ffmpeg

  Getting :

  checking for FFMPEG... yes
  
  checking libavformat/avformat.h usability... yes
  
  checking libavformat/avformat.h presence... yes
  
  checking for libavformat/avformat.h... yes
  
  checking for av_open_input_file in -lavformat... no
  
  configure: error: in `~/sox-14.4.1':
  
  configure: error: cannot find ffmpeg
  
  See `config.log' for more details

  Checking 'config.log' I see the following error :

  | #define HAVE_LIBAVFORMAT_AVFORMAT_H 1
  
  | /* end confdefs.h.  */
  
  |
  
  | /* Override any GCC internal prototype to avoid an error.
  
  |    Use char because int might match the return type of a GCC
  
  |    builtin and then its argument prototype would still apply.  */
  
  | #ifdef __cplusplus
  
  | extern "C"
  
  | #endif
  
  | char av_open_input_file ();
  
  | int
  
  | main ()
  
  | {
  
  | return av_open_input_file ();
  
  |   ;
  
  |   return 0;
  
  | }
  
  configure:15862: result: no
  
  configure:15935: error: in `~/sox-14.4.1':
  
  configure:15937: error: cannot find ffmpeg

  What am I missing here ?
  Thx !
