Larix Broadcaster Reviews

Over priced

Was looking to stream my kids ball games but $10/month for a couple games is way to much for how much I use it. Needs to be cheaper or have a lifetime license. There isn’t a lot of updates to the app so it’s just greed at this point.

Wish video stabilization mode worked

Love this broadcaster but if there were two things I wish it had… video stabilization that worked. Lots of settings but none work. Also wish there was a feedback mechanism in app vs having to go write a review with feedback for an app I pay monthly for. :)

Works but keep an eye on your stream

This app works great and has great customization features. Especially in regards to quality for low bandwidth environments. My only issue is the auto focus, the app will auto focus every other second and you can see it on the app and on the stream. If you change lenses, it’ll help a little but if you do it while transmitting then the audio encoder will crash and make everything sound like chipmunks. If these issues didn’t exist, I’d give 5 stars.

Getting worse and worse… Been using the app for over a year

UPDATE: I did update to your new version from 2 days ago, and the rotation bug is NOT fixed for overlays on PREVIEW, which I use extensively to read live chat and alerts! Its still upside down on preview and only right side up on the live end feed. Please test your product because its frustrating having to pay subscription for the product and be your QA as well. I use the software 5 days a week and this has been broken for 2 versions now, I can now only broadcast without live rotation mode until this is fixed… very frustrated. Had no problem with paying monthly fee except now there are more bugs than ever!! Latest bug makes overlays upside down when using live rotation mode, is there anyone even testing this app before releasing new versions? Not to mention it now crashes freq and does not support srtla … it was a good app I will give it one more week to fix the upside down overlays before deleting and cancel my monthly sub.

Eh… subscriptions

I loved the app when it was free now that it has subscriptions with bugs that have been there since the beginning it sorta is disappointing to see. The bug that I been running into is while swapping between cameras it sometimes causes the application to drop all audio. If that was fixed possibly maybe I’d consider getting the subscription but until then I’ll see myself out. All I can ask is to please reconsider I get it is better to get paid for your work but at least fix the bugs before you decide to make it a paid product.

Tooooo expensive

NDI hx camera is 20. 119/y is so crazy

Terrible

This used to be a very good app. Instead of creating new features and charging for those, they took features that we had already been used to for free and started charging for them. This is the opposite of the way apps should be.

Quiet but mighty!

Update July 2023: Instead of offering new, add on features behind a paywall, developers blanketed a $9.99 monthly charge on everything. Greedy and deceitful. 5 stars for functionality, 1 star for taking advantage of your customers. **** First for the developer: Can you add a switch to disable the iPhone’s image stabilization? I am streaming from a moving vehicle, and the smallest windshield vibration causes the stabilization to over correct resulting in jello. (It’s the phone not the app) I don’t know what else to say about this app, but it just does what it is supposed to. No gimmicks, no problems, just runs perfectly for hours on end. I used it with an iPhone 6 for 8hrs a day over 10 days to feed live storm chase video online. Flawless.

Money grab with no justification

I’ve used this app for years for RTMP streaming. Other than app development and bug fixes, rtmp puts no resource strain on the app developers. With the latest updates, they put a 30 min stream limit without paying $9.99/month (or continue with a watermark). I guess I’ll be switching back to a PC with OBS and HDMI capture instead. Charge for an upfront single purchase…reasonable. Charge high monthly fee with no lost resources… greedy money grab. 4 stars if they had kept it fair.

Pricing is absurd

You could pay $10 a month for access to 80 million songs no matter where you go in the world You could pay under $10 a month to stream hundreds of thousands of hours of produced television shows and movies anywhere in the world You could pay $10 a month to have hundreds of games to literally own forever Or you could pay $10 a month to suddenly have to remove a watermark on a live-streaming app What a joke. Fix your pricing.
