Yes, I have a similar problem. I can record videos, but the files generated from it are significantly too long (tens to hundreds of hours). Whenever I boot my phone I initally just get a screen showing "N/A" and after booting it initially always shows the date and time from when I first installed/booted up the rom. I suspect at least the first and last issue might be connected and the device/system somehow fails to keep the correct time at all levels and thus adds a lot of needless hours to the video file because one part of the system tells it it is whatever time it actually is and the other is stuck a couple days behind, making the resulting video several days long even though it's just a couple seconds.
Edit: audio and video also seem to be split, with one showing at the very beginning and one at the end. This is why I also think my problem might be the same as OP's as they only hear the audio (video might also be split).
Edit2: The issue of does not occur when setting the camera app to not record audio. Videos are appropriately short in that case.
