## TRANSCODING ON AZURE BROADCASTER CLUSTERS


ZEN Master now supports transcoding in Broadcaster clusters on Azure. When adding or editing a
Broadcaster cluster, select an instance name such as “Standard\_N\*” to choose an instance with an
embedded NVIDIA GPU.

MINOR IMPROVEMENTS AND BUG FIXES


• Improved styling of stream visualization Channel diagram and made it the default tab when
selecting a Channel.
• Stream visualization diagram now include Hitless and Transcoded Sources.
• Improved errors when Channel create/enable failed, e.g. if Broadcaster version doesn't support
required features the feature will be mentioned with the minimal required version.
• Creating or cloning a Target will now select the Target.
• Monitoring of S3 Targets no longer requires the S3 bucket to be public.
• Removed 'Low video quality' from Content Quality Analytics. It is superseded by ePSNR analysis
that will be available with Broadcaster V13.
• DASH outputs are now named “DASH + fMP4 HLS”
. Preview playback is currently available only
for the fMP4 HLS. Preview for DASH will be added later.
• Added a white background to TR-101 status icons in Grids for better contrast.
• Added info icons with tool-tips to clarify some fields.
• Can now force Remote Access tunnels to use regular HTTP; automatic HTTPS/HTTP detection fails
on some devices.
• Improved Source stats API.
• Improved events log filtering.
• Removed Azure locations that don't support the required API commands.
• Improved Source detection logic when multiple Broadcaster inputs with the same ID exist on
multiple Broadcasters in the same cluster. Should prevent ZEN Master monitoring an intra-cluster
Pull instead of the actual Source.
• Improved /events API command to include additional filtering options and response fields.
• Improved validation on many UI input fields.
• Fixed ZEN Master reporting a generic error instead of input offline when the input is offline for a
Broadcaster “Configure & Monitor” Source.
• Fixed a rare race condition causing notification emails to not be sent.
• Fixed object stats API call failing on time windows of more than 30 days.
• Fixed stream visualization when user has no view permissions on some objects in the Channel
graph.
• Fixed an issue preventing Broadcasters on AWS EC2 from being deleted if the machine failed or
was terminated via the AWS console.
• Fixed an issue causing pages to load with empty object list when using a link to a specific object
with cached search filter.
• Fixed monitor only Pull stuck in pending mode when monitoring a saved Pull with a stream
redirection.
