    Default NDVR Adaptive Streaming issues with SilverLight

    Hi,

    I have the nDVR add-on setup in an Origin/Edge configuration. When I push a single bit rate stream I am able to playback via nDVR with HLS, HDS, and SilverLight players.

    If I setup a smil file and push a stream at 2 different bit rates live playback works for all three players (HLS, HDS, and SilverLight). When I try to play back via nDVR it works fine for HLS and HDS, but not SilverLight.

    With SilverLight sometimes playback will start for a few seconds, or not at all and then I see the following errors get logged on the edge server:

    WARN server comment - DvrPlayerAdapterSmoothStreaming.timeToPlaylistIndex: Playlist alignment null store. t=2426494 stream=dvr-stream320.0 alignedEntry:null
    WARN server comment - DvrPlayerAdapterSmoothStreaming.timeToPlaylistIndex: Playlist alignment null store. t=2426494 stream=dvr-stream320.0 alignedEntry:null
    WARN server comment - DvrPlayerAdapterSmoothStreaming.timeToPlaylistIndex: Playlist alignment null store. t=2426494 stream=dvr-stream320.0 alignedEntry:null

    I have tried with multiple feeds and the same thing always happens with the SilverLight player when trying to view adaptive streaming content through the nDVR module. HLS and HDS seem fine. Any ideas?

    Thanks,
    Erik

    This is no longer an issue after I applied patch 14
