Just tested "SCR Screen Recorder Pro v1.0.5" on LineageOS 13.0 (Marshmallow), and it captured internal audio. I'm not sure why this feature is so elusive, but I appreciate this app being able to do so. Now that I know it is technically possible, does anyone know of a streaming app that can do it?
Side Rant:
I loved the concept of "Live in Five" by Avermedia, but it did not capture internal audio. In fact, as we know, nothing does except this app. But I am looking for something that can stream to RTMP (Twitch) and can capture audio. While this app is great for the YouTubers, us live steamers are still a bit boned
The app recommends "Gusher", a streaming app that wants $0.99/m, but did not see any option to capture internal audio, which is the original point of this app. So I am not sure why it is "Recommended", over the many other better solutions out there that have the same limitation. To be honest, I was unable to test "Gusher". I logged into my test Twitch account, got to the "Title /Game" screen, but every time I tried to enter a title or game, the update button was unresponsive, and "Start Broadcasting" remained grayed out. .......... But anyway this thread isn't about Gusher, though the developer did recommend it.
Update:
It adds some latency to the game audio. This won't work with rhythm games.
Warning:
After a few tests, I decided to uninstall the app. Uninstalling it through normal Android means locks up your device with a black screen, and I had to force restart.
Summary:
The app itself (SCR Screen Recorder) does what it advertises on my LineageOS 13.0 device. It induces some audio buffer.
It seems to get upset when you uninstall it.
