How do I record a ~45 minute 1080p video with external mic? I am currently using the camcorder function that comes with lgcamera because it allows me to use the microphone as the source of sound input. But I found that it stops when the recording size reaches 1.9GB (or 2.0GiB in the linux world, or about 16 minutes). I believe this is an arbitrary limit set by Android for apps? I googled and found some people reporting the same file size limit problem.
Is it possible to get around this file limitation problem (I have nexus 5)?
or is there a recording app that would break down the video into smaller sizes? The external mic is a requirement for me though.
If you know how to use external mic that with the native video recording app (1 hour recording limit), that would be even better. soundabout did not work for me.

I emailed Google about this here is the response I got:

"Thank you for contacting Google. I appreciate your patience with me as I look into this issue. It seems as though the limit placed on the video data file of 2gb is written into the android operating system. This is in effect on all types of android devices.
I have researched a few video control apps, they follow the same rule and stop at 1.9-2gb. At this time I do not believe there is a work around for this issue. I do not have software update information available either. Some of the research I have done points to a possible legislative law that limits the video recording time of mobile devices as it takes away from video recorders."
