Moblin is becoming more and more of a mobile control center
Version 35 doesn't reinvent the IRL stream. But the update improves exactly the areas that get annoying fast on the move: chat display, control from a second device, Twitch events, remote control, and the view of your own setup. The additions for 35.1, 35.2, and 35.3 are listed separately, and new features aren't counted more than once.
Moblin 35.1.0: SRT, ABR, and stability
The note on 35.1 that was already published stays as part of the version sequence. It covered, among other things, SRT 1.5.7, the ABR fix on iOS 27, better validation of manual Moblink relay addresses, and work on stream start, stream stop, repeated macros, and input fields.
Some of these points show up again in the later release notes. So the post doesn't say the same thing twice, they aren't explained one by one again in the 35.2 section.
Practical note: After an update, keep testing stream start, audio, SRT or SRTLA, ABR, Moblink, and the macros you use with your own configuration.
Moblin 35.2.0: only the additional points
The official notes for 35.2 overlap in several places with the 35.1 section we already have. So this lists only additions that aren't described there yet.
| Addition | What it means in practice |
|---|---|
| Kick login | a fix concerns playing the stream during login |
| Go-live notification | stream start can optionally be reported to the Moblin website |
| Face blur icon | the icon's position was adjusted |
| Macros on Mac | macros and actions can be deleted with a right-click |
The changelog also lists further work on Swift 6, workouts, and general usability. Points already covered under 35.1, such as SRT 1.5.7, ABR on iOS 27, Moblink validation, stream start, and repeated macros, are deliberately not listed again here.
No full IRL4YOU long-run test with 35.2.0 yet: This addition puts the official release notes in context. Before an important stream, a private test with your own setup still makes sense.
Moblin 35.3.0: what's new compared to 35.2
The official release notes mention a rework of the jitter buffer for incoming streams (ingests). That affects setups where Moblin receives a second camera as a video source, for example. Whether it noticeably changes your own setup can only be judged with a real-world test.
Background streaming with the camera preview turned on was also worked on. The developer explicitly describes this point as an attempt at an improvement, not a guarantee of error-free background operation. The changelog also lists new emotes in the alerts widget, display of anonymous Twitch gift subs, adjustments to the Twitch EventSub reconnect, and a fix for canceling the YouTube login. Macro events can now pass variables on to following actions.
IRL4YOU take: The ingest and background changes are especially interesting for mobile setups with several sources. We summarize the official notes here, which doesn't replace our own long-run test with Moblin 35.3.0. Before your next outing, check picture, audio, second camera, and scene changes in a private stream.
1. The most important changes at a glance
| Change | Benefit in everyday IRL use | Take |
|---|---|---|
| optimized chat display | less load from animated emotes and chat frames | especially interesting for long streams |
| Chat Phone Mode | focus a second device more on chat and moderation | handy with a phone on a gimbal or in a mount |
| Activity Feed | follow events in addition to the normal chat | can replace another dashboard |
| Remote control and macros | trigger actions from a second device | test with harmless commands first |
| Twitch Polls and Predictions | more community features right in the mobile workflow | according to the changelog, first-stage support for now |
| Bonding variable | make the bonding state usable for displays and workflows | check with your own setup before productive use |
2. Less CPU load from chat
Moblin 35 is meant to render animated chat emotes and the frames around chat messages more efficiently. That sounds unspectacular, but it matters on the move: chat, video encoding, overlays, cellular, and the display all load the same device. Every unnecessary constant load can increase heat and power draw.
So the update is mainly interesting for people who keep chat visible all the time or get a lot of animated emotes. You can't promise a fixed longer battery life from it. That still depends on display brightness, camera, resolution, frame rate, codec, cellular, ambient temperature, and cooling.
3. Chat Phone Mode: the stream phone can stay in its mount
The new Chat Phone Mode focuses the controls more on chat and moderation. That fits a typical mobile setup: the first iPhone sits on the gimbal, the chest mount, or a fixed spot and handles the camera and the stream. A second iPhone stays within reach and shows chat or controls.
That way the streaming device doesn't have to come out of its mount for every message. In Chat Phone Mode, the Quick Buttons are also hidden, and moderation actions are available in the main chat. If you want to use an older iPhone as a companion device, you can also use Moblin as a Moblink relay, provided the feature is set up properly.
Don't operate it while moving: On vehicle streams, chat and controls belong in the hands of a companion, or you only use them when stopped safely.
4. Remote control, macros, and messages to the streamer
You can run macros through the remote control assistant. The assistant can also send text messages to the streamer. Together with Quick Buttons, that gives you a control surface for recurring actions.
A macro can, for example, activate a prepared scene, set a marker, or bundle several harmless steps. A clear separation is the key: a button should have one understandable job. Too many chained actions make troubleshooting on the move needlessly hard.
- Test remote control on the same Wi-Fi first.
- Start with a harmless action.
- Protect access with a strong password.
- Only then add more macros one at a time.
- Keep a safety or private scene that you can reach manually.
5. Activity Feed and more Twitch features
The new Activity Feed adds events to the chat itself. Moblin 35 also brings first-stage support for Twitch Polls and Predictions, shows Watch Streaks and Shared Chat events on request, and expands moderation in Chat Phone Mode.
For IRL streamers, that can partly replace a separate Twitch dashboard on the second device. Still, before an important stream you should check which events actually show up with your own account and which permissions Moblin needs for that. Not every platform feature is necessarily available the same way in every account configuration.
6. Moblin 35 and SRTLA bonding in practice
For IRL4YOU, SRTLA bonding remains one of the most important Moblin areas. Moblin can use cellular, Wi-Fi, and connections provided through Moblink together. The goal isn't top speed but a sturdier uplink when individual paths fluctuate.
According to the changelog, version 35 adds a bonding variable. That will make it easier to bring the state into displays or workflows. Exactly how to use it depends on your own Moblin configuration, and you shouldn't carry it into a live stream untested.
Bonding remains a whole system: Several connections only help if the encoder, SRTLA, relay, bitrate, and latency fit together. If every available connection drops, even Moblin can't send a picture.
7. Testing before your next important stream
Moblin 35 changes many areas at once. That's exactly why you shouldn't install the update right before an important outing and use it untested.
- Back up your existing Moblin settings.
- Check picture, audio, and chat in a private test stream first.
- Test Chat Phone Mode with the second device you plan to use.
- Trigger remote control and each macro one at a time.
- Disconnect cellular, Wi-Fi, and Moblink connections one after another.
- Check that the stream, audio, and sync come back.
- Watch device temperature and battery drain for at least 30 minutes.
If you use SRTLA for several hours, plan a longer trial run as well. Controlled switches between cellular, Wi-Fi, and Moblink matter most, along with watching SRT latency over long sessions. That doesn't mean every setup will show problems, but a long-run test of your own is still worth it.
8. Sources and conclusion
Moblin 35 isn't one spectacular feature but a broad package of efficiency, usability, community features, and technical control. In our view, the lower chat load, Chat Phone Mode, and the extensions for remote control and bonding are the most interesting parts.
For existing users, the update is worth it if you actually need the new features and test them before going live. If you stream stably with your current setup, you still shouldn't switch right before an important date.
