I have made all the changes as mentioned in the article below and restart the engine:
I set myStream as the destination, but when I checked live > Incoming Streams > myStream on enginemanager, there is no incoming streams found. After I set as the article above mentioned, does the video being push to live > Incoming Streams > myStream? Or it still is mp4?
Besides, how is the playback URL looks like?
Anyone has any ideas?
