• StreamPlayerPlus allows the recording of live streams to MPEG-1, MPEG-2 and
MPEG-4 files. Once saved the files can then be installed on the EtherneTV VOD-W
server for playback. Make sure the "hinting" option is checked when recording MPEG-4
files.
• When recording MPEG-4 and MPEG-2 files using StreamPlayer Plus software, it is
advisable to keep the length of the record to under 50 minutes to facilitate creating
playlists and keep viewing time manageable.
• As the disks become full, the performance of head-seek times diminishes and streaming
performance may be affected. Purge unnecessary files and defragment as appropriate.
• Do not use spaces in filenames. Use underscores; for example:
my_history_class.mp4
.
• Apple QuickTime 6.5 or higher, with native MPEG-4 support, is the recommended MAC
desktop player for accessing MPEG-4 files from the EtherneTV VOD-W. QuickTime
supports the Seek feature (accessed through a slider-bar) for MPEG-4 streams. Make
sure
Edit > Preferences > QuickTime Settings > Streaming Transport
option is set to
Automatically determine the best protocol and port ID
or to
Use UDP, RTSP Port ID 554
.
• Over time, frequent asset additions and deletions may fragment the hard drive and
degrade VOD-W performance. To work around this issue and optimize performance,
you should periodically defragment the disk using the standard Windows defrag utility on
the
Accessories > System Tools
menu.
