MPEG-2 Index File Transfer
Some SGI Media Server clip formats, including MPEG-2 clips, have both clip content and
a companion index file. The index file has a clip content frame directory, consisting of
metadata and frame index information essential to play the clip correctly. Both the index
and clip content file must be transferred for these formats.
If the clip is being recorded and is subject to an FTP transfer to another server for playout,
transfer the index and clip files simultaneously. If concurrent transfer and playout is not
a requirement, transfer the index file first, and then transfer the clip content file.
Index files reside under the /usr/vtr/index directory and have the same name as
their companion clip. Index files are small compared to the content file they describe. The
/usr/vtr/index path is a non-real-time data partition managed by the
SGI Media Server.
Use a small window size with vtrftp. If you use a large window size (typical for clip
files), FTP will time out before the window is filled and you will get an incomplete index
file.
