Important : The script must detect what kind of video and it's size and output same video size in mp4 video file format.
I need a php library (demo script) where I can specify a video file (mp4,webm,..) and also a logotype , then the script will overlay that logo in the center with 70% of transparency and will create a new .mp4 watermark version, I need this fast and working for php + centos
input parameters : video source + logotype (png or SVG!)
output : video mp4
Developer must supply a working demo as requested.
