Hi, We’re planning to use Wowza streaming server to have multicast streaming over RTSP or HTTP in a corporate LAN. However after googling I found not many articles or official documentations on how to implement multicast streaming in Wowza. So any help on this? Thanks in advance.🙂 ---

Hi, The scheduler doesn’t track where the current video file is when it switches so it isn’t possible to restart from the exact location when the live switches back out. Roger. ---

My situation is that I would like to setup a playlist which contains videos that are scheduled to play at certain time. And I would like this playlist to be streamed over RTSP or HTTP in a multicast environment. I’ve been racking my brain to get this solved even after reading the article above. So any suggestion on my scenario? Thank you!🙂 ---

Thanks. I have created a playlist that is scheduled to play at certain time. Below is the playlist I created: > The above playlist will start at 4 Jul 4PM, and keep repeating itself. > > However, what should I do if I want to insert a video source from encoder(say, FMLE) to that stream(Stream1) in case I would like to broadcast some breaking news to the users? > > The flow should be as follows: ---

Hi, Thanks Salvadore, that’s a great module that I can use to meet my needs. However, what should I do in the following situation? Stream1 is playing scheduled videos (for instance, when live source comes in, it was playing 05:00 of item 2 in the playlist). When live source ends, how to I configure it so that it can return to 05:01 of item 2 in the playlist? Sorry for my bad English. I hope you can understand. Thx
