The following is an example directory structure for a recorded stream of length 1 hour and
10 minutes:
0000_00_00
0000_10_00
0000_20_00
0000_30_00
0000_40_00
0000_50_00
0001_00_00
0001_10_00
manifest.txt
Using the folder named 0000_00_00 as an example, the initial contents would be:
A-0000_00_00_000.m4fa
dvrManifest_0000_00_00.txt
M-0000_00_00_000.m4fm
V-0000_00_00_000.m4fv
The file naming convention is the same as the directory naming with an additional
millisecond value represented by mmm:
HH _ MM _ SS _ mmm .
.m4fa and .m4fv files
Wowza nDVR creates .m4fa audio and .m4fv video files, which are based on the MPEG-4
multimedia container format. Together, these files represent a chunk of recorded audio and
video content that's used for playback of your recorded stream.
You can't play these files directly. However, they are required and referenced when you play
your live recorded stream using nDVR. If you delete or move these files, playback errors will
occur. If your configuration changes and you must move recorded files, make sure that the
corresponding
DVR/StorageDir property is updated in your configuration.
Currently, concatenating these recorded files into a single on demand file for later use isn't
supported.
