is this is possible to playback the recorded video from wowza stream engine?

Hi team ,

We are working on the wowza gocoder SDK for iOS and we need some options like we need to post a video for 20 seconds and once we recorded to 20 seconds then we need to playback the recorded video to verify it(as like catsup status).is this is possible by using wowza gocoder SDK(wowza stream engine).

And is this possible to record the live stream video and if possible how to get the recorded video from wowza stream engine?

You should take a look at our nDVR. It will allow a person who wants to catch up on a live stream if they came in late.

You can also take an nDVR store and convert it to MP4 for playback later if you wish.

You can also record all live streams directly to an MP4 file, but note that you will not be able to play the file until the live stream is done.
