• While ffmpeg convers via php website doesnt work

  29 octobre 2013, par Xenos Trojanowicz

  So im using

                  if ($success_msg) 
  
              {
  
                  $tmp_parts = explode('.', $file['name']);
  
                  $ext = array_pop($tmp_parts);
  
                  $ext = strtolower($ext);
  
                  if($ext == "avi" && $convert_avi == true)
  
                      {
  
                          $convert_source = _VIDEOS_DIR_PATH.$new_name;
  
                          $conv_name = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
  
                          $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
  
                          $ffmpeg_command = 'ffmpeg -i '.$convert_source.'-acodec libfaac -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$converted_file;
  
                          echo exec($ffmpeg_command);
  
                          $sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
  
                          $result = @mysql_query($sql);
  
                          unlink($convert_source);    
  
                      }
  
                  echo $success_msg;
  
              }

  This code to convert videos from avi to mp4 but i have another big issue when i upload big file let say 170 mb it converts about 25 minutes or so and while it converts website doesnt work for me.

  NOW I KNOW WHY WEBSITE DOESNT WORK :

  • its only for me becose system doesnt open extra slot to enter to website while it converts
  • i know how to solve this problem with cronjob but im afraid that if something goes wrong it will be biggest fail i ever had

  so im hopping that u guys will suggest something smart and easy to deal with this issue

• Mingw-w64 - printf does not work

  27 décembre 2013, par Gosha U.

  First I wanted to modificate ffplay according to my requirments. Then I noticed that original ffplay from my build can't play some video files, but it didn't write any message to console. Then I noticed that ffmpeg also don't write any usage message when I run it without params. But it works. If I run it from terminal it's like running asynchronously ! The terminal just shows next row. I mean it asks for a next command. But the ffmpeg process is visible in task manager and it writes the output video file what I had requested !

  I created following souce file. I have modified the Makefile. So it have built the exe-file works just the same way. I have no idea how it can be.

  #include 
  
  #include "cmdutils.h"
  
  
  
  const char program_name[] = "hello";
  
  const int program_birth_year = 2013;
  
  
  
  void show_help_default(const char *opt, const char *arg)
  
  {
  
      printf("zxcvbnm\n");
  
  }
  
  
  
  int main(int argc, char **argv)
  
  {
  
      printf("1234567890\n");
  
      return 0;
  
  }

  And after that I created real hello world app with MinGW-w64 and qmake without eny extra libs. And its printf does not work.

  I want to prevent this behavior.

  I want to make printf working in traditional manner.

  How I build FFmpeg :

  PKG_CONFIG_PATH=/home/developer/workspace/MinGW32fs/lib/pkgconfig/ \
  
  SDL_CONFIG=/home/developer/workspace/MinGW32fs/bin/sdl-config \
  
  ./configure \
  
    --prefix=/home/developer/workspace/MinGW32fs \
  
    --extra-ldflags="-L/home/developer/workspace/MinGW32fs/lib" \
  
    --extra-cflags="-I/home/developer/workspace/MinGW32fs/include" \
  
    --arch=x86 --target-os=mingw32 --cross-prefix=i686-w64-mingw32-  \
  
    --pkg-config=pkg-config   --enable-libtheora --enable-libvorbis --enable-libvpx \
  
    --enable-outdev=sdl --enable-shared --disable-static \
  
    --disable-doc --disable-manpages --disable-podpages
  
  
  
  make

• Revision c807949408 : Prevent left_block_mode stepping into left tile This commit uses left_available

  22 octobre 2013, par Jingning Han

  Changed Paths :
   Modify /vp9/common/vp9_findnearmv.h

  
   Modify /vp9/decoder/vp9_decodemv.c

  
   Modify /vp9/encoder/vp9_bitstream.c

  
   Modify /vp9/encoder/vp9_rdopt.c

  
  
  Prevent left_block_mode stepping into left tile

  This commit uses left_available flag to decide if the left mode_info
  struct is available for left_block_mode. As discussed with James
  Zern (jzern@), this prevents the codec from fetching mode_info from
  blocks in the left tile, which although effectively not used might
  present concerns for multi-threaded tile decoding.

  This is NOT a bit-stream change.
