- Please advice how to use “ndvr convert” function to download an individual and partial mp4 file during live stream broadcasting.
- Tried wowza converter function in the paid license wowza and still failed.
- E.g. [http://192.168.x.x:8087/v2/servers/](http://192.168.x.x:8087/v2/servers/)_defaultServer_/vhosts/_defaultVHost_/applications/AppEng/instances/_definst_/dvrstores/production.0/actions/convert
