Hey everyone, we've released the long awaited 3.5 update! We're quite happy with the changes and hope you'll enjoy them as well.

Downloads can be found here, and the full changelog can be found here.

Noteworthy Changes

Interface Updates

We've added the necessary web glitter and dark skin sleekness to ensure the interface is deemed "slightly prettier". The change isn't too different from our old interface; however, it's much easier on the eyes, and a few sections have been made more compact.
The biggest change is to the "Streams" page, where we have moved most of the subpanels under the new "Actions" button, which can also be accessed by right-clicking when the stream is highlighted.
Clicking on the stream name will bring you to the preview page, and hovering over the stream name will display the source.
Several other actions, such as stopping the stream, invalidating the sessions, or hard restarting through a "nuke stream" command, are available as well.

(f)MP4 Input Support

We have added fragmented MP4 support to our MP4 capabilities for both MP4 files and HLS (CMAF) streams. This means MistServer should now be compatible with almost all HLS URLs, unless the codecs within the HLS are unsupported.

(Haivision) SRT Updated & Full-Featured Single Port Setup

SRT has been updated to version 1.5.4, and versioning has been added to the protocol in INFO-level messaging. The version will also appear in the protocol panel during setup.
We’ve also managed to update SRT to fully spawn separate processes using the same port, which increases both stability and efficiency.
To learn more, we recommend attending FOSDEM 2025 (February 1–2, 2025), where Jaron will explain how we achieved this and what the advantages are. Details can be found here. Once recordings are available, we’ll share them in a follow-up post.

Creation Time Added to MKV/WebM Outputs

This update makes it easier to identify the creation date of a recording and allows UTC timestamps within the recordings. It adds flexibility, especially when timing is important.

Windows Installer – Fixed Permissions for Microsoft Accounts

Windows users with Microsoft accounts previously experienced MistServer with partial permissions, leading to various issues during usage. We’ve rebuilt and properly configured the installer to resolve this problem.
If you use a Microsoft account, we recommend running the updated installer.

Various Small Updates & Improvements

Several smaller improvements have been made to the code, resulting in better resource usage.

Known Issues: Windows UDP-Based Protocol Support Not Working

During updates to our UDP socket implementation, we encountered a limitation in Cygwin that breaks Windows support for the latest improvements. We are working on a fix to enable Windows to use WebRTC, SRT, and RTSP over UDP with a native Windows UDP socket implementation.
If SRT is critical for your setup, we recommend using our 3.4 build for Windows in the meantime!

New Guides Available

We’ve updated several guides in the online documentation, including:
- WebRTC Playback
- Adding GStreamer Encoding
- How to Generate Live Streams
- Example on Geo-IP Blocking

We’ve also refreshed our documentation on starting Docker builds.

Hello everyone!

We've added a new guide on how to add encoding to a stream using stream processes and FFmpeg. We're planning on adding a Gstreamer version as well as we can't be playing favorites.

Encoding is something that is often requested and hopefully this guide will help explaining how to set it up within MistServer. Just keep in mind that your encoding possibilities very much depend on your own server resources!

If you have any questions or wonder how to set something up specifically feel free to contact us

Hello everyone!

We will be returning to IBC this year as well This year you'll find at booth 5.F43. Joining us this year will be Sipradius, together we've made some exciting solutions we'll be proudly showing off.

So be sure to drop by if you want to see the last things we've been working on. Pick our brain about how to solve something, or simply drop by to steal our chocolates.

Hey everyone,

We've been quite busy with setting up the 3.4 release, now that we're done we'll start releasing more articles and how to guides. The first one up is how to push WebRTC WHIP into MistServer using OBS. It's already available in our online documentation right here.

Noteworthy changes

Windows builds!

We finally have releases of Windows builds for 3.X, starting with this version. The MistTray taskbar icon application has not yet been updated, so this release does not include it. MistServer should now be ran using the MistServer Shell shortcut. This boots MistController in a shell window (which you can minimize to get it out of your way, or keep in view to see the logs in it).

There will still be a few differences in the Windows builds compared to Linux (most notably: WebRTC is not functional in the Windows build right now), but future updates will incrementally get Windows and Linux builds to parity again.

Web interface: New stream status page

The stream status page is a new tool in the web admin interface to more effectively analyse the current state of a stream. It also allows the following actions:

• Add tags
• Stopping viewers
• Stopping sessions
• Nuking stream (forceful reset of the stream)
• Look at the meta-data of the stream
• Easily identify the live point for each track and their respective sync/delay
• Creating/removing triggers
• Starting/stopping pushes
• Starting/stopping recordings

Raw pixel support

Usually you don't want to handle raw pixels in a modern media server, but in some cases it is unavoidable. MistServer now supports a new custom data structure optimized for raw video streams, and WebM/MKV-based inputs/outputs/processes have been updated to support raw pixels.

V4L2 Support (Linux only)

You can now use V4L2 to directly access webcams and other compatible devices with MistServer. Both raw pixel mode and (M)JPEG mode are supported.

RTMPS push input and pull output support

You can now set up RTMP with an SSL certificate to support incoming RTMPS connections. (Outgoing RTMPS connections have been supported for several versions already.)

WebRTC datatrack support

WebRTC (both WebSocket-based signalling and WHEP signalling) now have support for datatracks to receive JSON-based data track messages in sync with playback. Ingest support and trick play signalling over datatracks will follow at a later date.

New settings for processes

The restart behaviour can now be configured, allowing you to set how processes should respond to failure conditions. Stream processes can now be marked as inconsequential (meaning they will not impact when a stream is considered available).

Goodbye Cmake

Support for building MistServer using Cmake is now officially dropped. MistServer can only be build using Meson starting with this release.
