We have problem with NDVR, because after some time video codec missing in declaration of HLS playlist and some players then play only audio… We have recorded both… We observed, that situations occurs, when directory 0000 is purged(mostly remain) via window settings…Is possible to manually add video codec ? this is serious problem…

#EXTM3U  
#EXT-X-VERSION:3  
#EXT-X-STREAM-INF:BANDWIDTH=5434778,CODECS=“mp4a.40.2”

and right is:

#EXTM3U  
#EXT-X-VERSION:3  
#EXT-X-STREAM-INF:BANDWIDTH=5431479,CODECS=“avc1.100.40,mp4a.40.2”,RESOLUTION=1280x720
