I had my friend who is fluent in both languages spoken in India translate it here's what he said...
Those people that are video taping were yelling at those people who were in the water to hurry up because the water was approaching fast, and they need to get out soon or they are going to get swept. And towards the end they were all saying they are dead because they are no where to be seen and one said he is sure they are all dead because of all the stones. And they were calling the cops/rescue people at the end and saying five people went over the fall and you guys need to hurry up and help them get rescued, he was also telling them the location of the place some picnic spot.
