I used the vpn trick to update to android pie and have magisk installed. Everything works fine, 4g wifi etc. However, I noticed in the stock camera app video recording does not work. I can take pictures both on front and rear cam. When I enabled hyperlapse or slowmo, it can record video but never when those features are not enabled. I tried installing Open Camera from playstore (an opensource camera software) and tried to record video with that app but still nothing. It says "Failed to record video". I recently also enabled camera2api and installed gcam and it can take pictures but not record video. Weird thing is that I tried capturing video on Facebook Messenger and it worked. Video recording works on messenger but not on camera apps?? Did anyone experience this or is it just me?

Try to record video without audio in Open camera. If it works, download Cinema FV camera app and try different audio codec. It happened to me on Oreo, I couldn't find the reason. Once the full ROM has been released by Xiaomi, I reflashed it and video started to work in all apps again. Maybe something went wrong during OTA update, hard to tell. All I know is that it messed up with audio codecs and I had to use another as the default one to be able to record video with sound.

Hmm you're right the problem is with the audio. I tried open camera and disabled audio and it worked. I also followed your suggestion and installed cinema fv camera app and tried all the different codecs but it still doesn't work. It works though if I disable audio completely. Maybe I'll just wait for the new security patch to come.
