Max release 10.1 is now available for all Max devices. Please be sure to refer here for release notes. Below is a list of some exciting features Max offers and some known behaviors in this software version.
LiveEdge® Max Features
-
WebRTC/WHIP Output Support
-
WebRTC (Web Real-Time Communication) offers a modern ULL output direct to web, a great way to monitor the stream in real-time full raster and frame rate
-
-
Opus Audio Profile/Encoder Codec Support
-
A requirement of WHIP integration support, Opus audio codec is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype’s SILK codec and Xiph.org ’s CELT codec.
-
-
Remote XML Configuration Support
-
LiveEdge® Max now supports the remote management XML control feature to streamline XML-enabled workflows
-
This feature will be enabled on all LiveEdge® Max devices by default that are shipped out operating on software version >V10.1.0. If you have a Max device that was shipped with <V10.1.0 local software version, please contact Videon Support to assist with enabling XML on your device!

Known Behaviors
-
External Storage:
-
External storage device functionality may have unexpected results
-
External USB storage devices are not supported with this release of software.
-
An SD card must be inserted prior to device boot in order for it to mount properly. SD cards being removed from the system post-boot will require a reboot to remount them.
-
Internal Device Storage will now mount and allow normal recording functions.
-
-
-
WHIP/Opus Audio:
-
Opus Audio is supported for WHIP video and Unicast output options.
-
WHIP outputs may be configured for a video-only stream
-
WHIP outputs only support H.264 (AVC) video profile/encoder to be selected and do not support H.265 (HEVC) video profiles/encoders
-
WHIP outputs only support Opus audio profiles/encoders to be selected and do not support AAC audio profiles/encoders
-
If you have selected the WHIP output and no video profiles are selectable for the Video Source but you have created a video profile/encoder, it is most likely because WHIP requires H.264 with no B-frames (Lowest Quality/Latency).
-
XML Control for WHIP Video and Opus Audio is not supported in this release. The local web UI and LiveEdge® Cloud Control, or REST API are recommended for controlling these features in the 10.1 Software Release.
-
-
Video and Audio Profiles/Encoders:
-
For video profiles/encoders, H.264 (AVC) / H.265 (HEVC) codec selection is assigned upon the creation of new profiles/encoders. This is no longer a modifiable setting within the video profile/encoder after it has already been created.
-
Only “Normal” and “Lowest” Quality/Latency settings are supported in Video Profiles/Encoders.
-
B-frames are not strict in the encoding architecture and are “adaptive”, meaning you may not see consistent IBPBP...BPBP GOPs. Sometimes it skips B-frames, so you can see GOPs like IBPBPPPPPBPBP. The higher the bitrate, the more B-frames get skipped.
-
B-frames in the GOP structure are not supported on Max with Constant Bitrate encoding mode. When streaming with Constant Bitrate encoding mode, please select “Lowest” Quality/Latency.
-
- XML Control
- SD cards with XML files installed will not function on LiveEdge® Max
-
XML Control will sometimes take up to 90 seconds to apply the changes that have been configured to an XML file.
-
XML Control-created Data Profiles/Encoders are not properly deleted when removed from the XML file.
-
We recommend manually deleting any Data Profiles/Encoders using LiveEdge® Cloud Control or the local web UI after a Data Profile/Encoder is removed from the XML file. If you allow the Data Profiles/Encoders to exist, they will still be re-used in a new XML file containing them.
-
- Local Web UI
- When performing a Reset Settings procedure on the local web UI, users are likely to encounter a completion notification too early before the system is ready to save new configurations. Please wait for 2-3 minutes after performing a Reset Settings before making any other configurations.
