Hello,
I've been using vMix for a while at my church (almost finishing the trial period and then I'll maybe buy it), and everything was working just fine. This is honestly a great software for professional broadcasting.
However...
From the last week, I've been having some pretty bad problems that affect the stream quality and the program usability.
Problem #1First of all, FFMPEG fails with the following error whenever hardware encoder is enabled on a stream output other than number 1 (I believe...)
(Here's the full report):

The above makes zero sense, it started out of nowhere, and it's making me use the CPU as an emergency measure, otherwise goodbye stream and credibility...
Now, problem number two is the worse of them.
Problem #2We grab the church audio from the main mixer through Line-In. It works just fine, you can monitor it in your headphones just fine from vMix. However, when you're watching it through Android phones and some iPhones, the audio from both YouTube and Facebook is extremely crunched/glitchy, not even recognizable. I've noticed this is
only the case with our audio input from the mixing console, because when we broadcast media files, the audio works just fine.
The audio works fine when we mirror the screen using a Chromecast or play the audio through a Bluetooth speaker.
I hope you guys can help me, I don't want to switch our broadcasting software
again. It's a lot of work. But this is seriously making me think 3 or 4 times before making this investment. It already has a difficult-to-handle price (especially for us in Brazil with our extremely devalued currency and abusive taxes).
