• How to get FFMpeg code working on remote server ?

  4 février 2016, par OMi

  I am using the following code to add plain text to videos. It works fine on localhost with EasyPHP server but I am not able to get the output on server (ffmpeg hosting). In addition, video conversion, video to audio everything is working fine.

  @exec('ffmpeg -y -i '.$source_file.' -vf drawtext="fontfile=font_omiA.ttf: \ text='.$watermark_text.': fontcolor=white@0.5: fontsize=20: \ x=(w-text_w)-3: y=(h-text_h-line_h)+10" '.$output_filename.'');

  I tried with following code too but I didn’t get success :(

  @exec("ffmpeg -y -i ".$source_file." \"fontfile=font_omiA.ttf: \ text=".$watermark_text.": \ fontcolor=white@0.5: \ fontsize=20: \ x=((w-text_w)-3): y=((h-text_h-line_h)+10))\" ".$output_filename."");

• FFMPEG Code Understanding

  13 avril 2016, par Edge

  I have the following code :

  }
  
      private function getIntroVideoFile() {
  
          global $upload_dir;
  
          foreach ($this->myusers as $user) {
  
              $sql = "SELECT  IntroVideoFile from IntroVideos 
  
                  where IntroVideoID in (select IntroVideoID from EventInfo where EventInfo.PackageID = '{$user->packageid}' and EventInfo.SlotID = '{$this->curSlotId}') ";
  
              $row = db_fetch_item($sql);
  
              $user->introVideoFile = $row['IntroVideoFile'];
  
  
  
              exec('ffmpeg -re -i "'.$upload_dir.$user->introVideoFile.'" -sameq -vcodec copy -acodec copy -f flv rtmp://XX.XX.XX.XXX:1935/live/'.$user->username . ' >/dev/null 2>/dev/null < /dev/null &');
  
              echo "Starting play ".$user->introVideoFile."\n";
  
          }

  Please can someone explain to me what is happening here.

• Build cpp code to run FFMPEG command in Anroid after generating .so file

  22 octobre 2020, par Nikhil Solanki

  I built FFMPEG so files(libavcode.so, libavfilter.so, libavformat.so,libavutil.so, libswscale.so) by following this tutorial. This tutorial is nice is helpful to build your own .so files as per your library requirement.

  


  Why I am building own one ?
I know that there is some already available libraries in github like bravobit's, tanersener's and also microshow's. These all have certain limitations like some of this will not work for target SDK 29 & 30 and tanersener's lib is good but there is problems with -filter_complex command's output and micrshow's lib is crashing in android 10 and 11 beta ! So, all have specific problems. So, I am considering to create own one.

  


  What I have and already done
After following tutorial(mention in above) I successfully generated .so files and put it into my App.

  


  Here is the screenshot of which I already done .so files :


  


  So, you can see that I put all files into cpp folder. As per version I only need ARMV7 and AMR64.

  


  What is the problem ?

  


  Problem is that I have no idea how to create .cpp file to execute command and what is it actually and how to use it ? I also tried some other libraries .c code but it didn't work for me. So, what is the code of cpp which can execute command ? Is there any other way of this ?

  


  Note of this requirement
We can't run any executable file directly from directory in Android because its restricted in target Android 10 and 11. So, we compulsory need to build native code and call class or it's function.
