The topic is self descriptive.
I'm using KODI with TVH PVR client but it's on Android based TV Box.
I know with ffmpeg is relatively easy under Linux OS, like:

ffmpeg -i pipInput1.flv -i pipInput2.flv -filter_complex "[1]scale=iw/5:ih/5 [pip]; [0][pip] overlay=main_w-overlay_w-10:main_h-overlay_h-10" -profile:v main -level 3.1 -b:v 440k -ar 44100 -ab 128k -s 720x400 -vcodec h264 -acodec libfaac PIP_output1.mp4 

ffmpeg -i master_video.mp4 -vf "movie=second_video.mp4, scale=800:-1 [inner]; 
[in][inner] overlay=70:70 [out]" completed.mp4

ffmpeg -i rtsp://serer/mp4:1.mov -i http://serer2/sample-video2.mp4 -filter_complex “[1]scale=iw/4:ih/4 [pip]; [0][pip] overlay=main_w-overlay_w-10:main_h-overlay_h-10″ -ar 44100 -f flv rtmp://localhost:1935/Stream

Could be possible to be created such PiP IPTV ability server side ?

Thanks to anyone in advance.
