Hi,

  Following  is the sample  watermark command
   D:/test/ffmpeg.exe -i D:/test/index-720p194.ts  -i D:/test/watermark.png 
-filter_complex 
"[1][0]scale2ref=w='iw*40/100':h='ow/mdar'[wm][vid];[vid][wm]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2"
 -preset fast -codec:v libx264 -c:a aac  -s:v 1280x720 -b:v 1500k -maxrate:v 
1500k -bufsize:v 750k -copyts -y D:/test/tmp-index-720p194.ts

   This command is working and I can see watermark overlayed.

   But this is causing loss of audio
   Can you suggest what arguments I need to pass so that I will not loose audio 
frames
   and regenerate correct timestamps

  When I run this fragment using hls.js
  I get following error Audio frame @ 582.005s overlaps nextAudioPts by -46 ms.


Thanks
Vara Prasad
