Fantastic Restream Integration & Wonderful App
Every once in a great while you stumble across an app that just comes out of the gate doing everything nearly perfectly, and this is one of those apps. After live-streaming music from a full desktop setup for a few months due to quarantines I was looking for a way to take my multi-platform streaming solution back out to live gigs with the same improved audio & video quality I was able to achieve in a studio setting.
Many other apps and in-platform streaming solutions exist but provide limited functionality over video resolution, audio interface selection and encoding, etc. Larix allows me to do absolutely everything I did in the studio, including using a stereo external USB audio interface, customizing resolution and bitrate, recording locally, and streaming to multiple platforms. Literally the ONLY change is a step down to an iPhone camera from a full external DSLR, and that is absolutely incredible.
I cannot say GOOD JOB loud enough with this one, and I can’t wait to see where the team goes from here!
Thanks for making this.

Dave, thank you so much for a great review! Our team wants Larix to become full featured camera for remote production "on-field" streaming so if you have any thoughts on how we could make it better, just let us know via email@example.com . Thanks!
Quiet but mighty!
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.

Thank you for your feedback! We'll check the stabilization option.
Audio issues with recent update
Long time user and huge fan of this excellent application. That said, with one of the recent updates, we are now experiencing audio anomalies that are not hardware related. We use Larix and Facebook live to stream our services and there is now a loud distortion/popping anomaly that occurs with increasing frequency the longer the stream runs. Not sure how to proceed in isolating the problem and was not able to locate a proper channel to reach support. Any advice would be appreciated.

Can you please report us with more details via firstname.lastname@example.org ?
