在Android中如何使用ffmpeg在已录制的视频上添加文本作为水印？

Question

I am trying to set text as a watermark on already recorded video but it is not working. As I tried image.png as a water mark and it works by following this url http://androidwarzone.blogspot.in/2011/12/ffmpeg4android.html

Command for apply image as watermark on already recorded video:

String[] complexCommand = {"ffmpeg","-y" ,"-i", videoPathHere,"-strict",
"experimental", "-vf", "movie=" 
+ Environment.getExternalStorageDirectory().getAbsolutePath() 
+ "/watermarkImg.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]",
"-s", "160x120","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab", "48000", 
"-ac", "2", "-ar", "22050", 
Environment.getExternalStorageDirectory().getAbsolutePath()+"/watermark.mp4"}; 

but when I tried to implement text as watermark its not working:

String[] complexCommand = {"ffmpeg", "-y" , "-i", videoPathHere, "-strict", "experimental", 
"-vf", "drawtext=fontfile=" + file + ":text=TestText", "-s", "160x120", "-r", "30", 
"-b", "15496k", "-vcodec", "mpeg4", "-ab", "48000", "-ac", "2", "-ar", "22050", 
Environment.getExternalStorageDirectory().getAbsolutePath()+"/watermark.mp4"}; 

Even I tried this also https://video.stackexchange.com/questions/15551/ffmpeg-drawtext-filter-create-transparent-background-with-text

but it is also not working in my case.

So, what is going wrong with adding text as watermark?

I make changes in commenad from ;text=TestText to :text=TestText then it shows given error.
