I do not use or have a decent Android device unfortunately, sorry about that. I understand the pain, that’s why I created my own app. 🫂
It sucks that there is FFshare on Android exactly for that, but the defaults are horrible and custom options output is buggy... https://github.com/caydey/ffshare/issues/150
The idea that I'm uploading huge and slow video to my media server is causing me almost physical pain.

No need to apologize. You created an awesome app. I'm just sad that there is foss solution on Android, but it seems to be abandoned and the last version sucks. :-(
