What device are you running on? Also, you need to specify the path with like /sdcard/ or use the API to get the external storage path.

JJTech0130 commented

Yeah, I changed it to /sdcard but forgot to update the issue. It's running on a control hub.

Windwoes commented

So, I never actually tested the recording feature on a control hub... I do know it worked on Nexus 5 phones.

I can reproduce this not working on a Control Hub, but I don't get a segfault. Instead I get a failure in the RockChip video codec initialization:

I made a standalone test app to test using the MediaRecorder with an external surface (what EOCV does) as well as binding directly to an Android Camera (v1) instance, and both of those work fine on a Nexus 5 and fail with the above error on a Control Hub. I think something is fundamentally broken with the video encoder engine. Surprisingly, the Open Camera app is able to record video on the Control Hub, so that indicates that maybe there are certain configurations that work and others that are broken, I'm not sure. @NoahAndrews any thoughts?
