How to watermark videos (PHP+ffmpeg on linux)
I'm developing a video download website. We strore videos in FLV format. We convert them to 3GP,MP4 or AVI on user request.
But the problem is people re-distribute those videos without our copyright. So we thought to add a watermark to videos.
We want to add a our banner image at the start of the videos or add our logo in a corner of videos. We use ffmpeg to convert videos and think we will can do this job using ffmpeg. Our ffmpeg version details below.
Please help me for this job.
