 String filter="";
 for (int i=0; icode></extratl>

How to add text on a video using FFMPEG in android
19 juin 2014, par Divya MotiwalaI am trying to add text to the video but not getting the syntax right.
I am forming the command as a string (given below) :String concatePath = "data/data/"+ this.getPackageName() +"/cache/ffmpeg" + " -y -i " +
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)+"/Camera/wildlife.mp4 -vf " +
"drawtext=fontfile=/system/fonts/DroidSans.ttf\\: text='this' \\:x=(w-text_w)/2\\:y=H-60 \\:fontcolor=white \\:box=1 -y "
+ Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC)+"/test/output_text.mp4";So the command that gets executed is :
data/data/com.example.videomerger/cache/ffmpeg -y -i /storage/emulated/0/DCIM/Camera/wildlife.mp4 -vf drawtext=fontfile=/system/fonts/DroidSans.ttf\: text='this' \:x=(w-text_w)/2\:y=H-60 \:fontcolor=white \:box=1 -y /storage/emulated/0/Music/test/output_text.mp4It is giving the error :
Unable to find a suitable output format for ’text=’this’’
, text=’this’ : Invalid argumentHow to solve it ?
Update : I could add text to the video but it takes only single words. When i give space for multi words, it considers it as an invalid argument ! How can i add space to it ?
