User Manual

l The ability to perform an FTP Delete cannot be disabled, even after using the Disable FTP Delete command
in the FTP session.
Workaround: Ensure that access to control of the FTP session is restricted to those aware of decisions about
deleting the stream.
l Extracting tracks from an .MP4 recording when there isn't enough storage space for the extracted files causes
the extracted files to become corrupted.
Workaround: Check how much internal storage space is available on Pearl-2 and delete any unnecessary
recordings to free up more space.
l Occasionally, tracks won't extract from a 64 GB .AVI multi-track recording using the Admin UI.
Workaround: Perform the extraction again.
l If AFU is configured for a channel that is paired with an AV Studio account, recordings that are in the AV Studio
queue are deleted after the AFU file is uploaded.
Workaround: Do not configure AFU for channels that are paired to AV Studio.
l Some audible clicks are present during playback of AAC formatted recordings at 48, 44, and 22 kHz when using
Microsoft Edge versions 41-42.
Workaround: Use a different web browser to playback the recordings.
Affecting the Admin panel
l Passwords and IP restrictions set for viewers don't restrict access when using certain common platforms or
when set on a per-channel basis if your stream uses HTTP Live Streaming (HLS) because HLS is processed
directly by the apache server.
Workaround: This only applies if you're using a password for the stream. The only common platforms where
this is a know issue are VLC and iPhone6, iOS 10.0.1, and using another platform prevents the issue. If you're
streaming over HLS, do not set viewer passwords and IP restrictions per-channel. Use global viewer passwords
and IP allow/deny lists instead.
l It is possible to name two or more channels with the same value. Use of automatic file transfer and UPnP is
unpredictable if this occurs.
Workaround:Ensure each channel has a unique name.
l The automatic file upload (AFU) file queue shows a maximum of 15 files, Newer 15 and Top of the list buttons
do not work. All files are transfered, even though they are not listed.
Workaround: Wait for the queue to have fewer files in the list. Use global viewer passwords and IP allow/deny
lists instead.
l Cropping a video source to 16:9 using the layout editor may not scale correctly and can appear as a thin line in
the layout editor. This happens when the device or web browser you're using with the admin interface has a
different approach to composing layout. Recording and streaming are not affected.
Workaround: Due to color space limitations (YUV with 2x2 subsampling), the cropped region's dimensions
must be set to even values.
l Authentication to Pearl-2 using DNS login will often fail for Windows Edge, and on Mac OS X 10.10 with Safari,
Chrome, and Firefox.
Workaround: Use a different web browser such as Chrome or Internet Explorer, or use a different OS.
l When streaming to the Wowza streaming cloud, the Transcoder state field always displays a status of "starting"
even after the stream has started.
