UPDATE!!!! script. I have used the same script for 2 videos and picture int he middle with audio but this time I have added a lot more videos and audio and pictures in the middle. each one has ten different videos and picture and audio
so there would be 20 different videos, 10 pictures and 10 audio files. all uploaded into a server. it would be video would play and finish the video with 1000ms and 400 ms gap and then static picture with audioa nd then 400 ms gap and then video again needs to finsh playing. I have uploaded all 35 vidoes and 15 audios and 35 pictures into a server (will be adding more).
My script and my csv file are below. But when I run the script and I get to the main Template which containes the experiment and it goes to the first video before the middle one. It just shows black screen with play button that u cannot press play and it is stuck at that canvas with the black screen.
