In Android, Is It Possible To Change Camera (from Front To Back) And Still Keep Recording?

That's my question :). If I start recording using the Front Camera with the MediaRecorder and then switch to the back camera, is it possible to keep recording using the same video

Solution 1:

You can do it on Nexus9 with camera2 api. (Nexus5 can't open 2 cameras at the same time)

• Create 2 Gl contexts(Shared) and 2 texture buffers.
• Create a TextureView for previewing.
• Create a MediaRecoder for recording.
• Open front and back camera.
• Make repeating request that output target is texture buffer.
• Render scene with 2 textures to TextureView's surface for each frame.
• Render scene with 2 textures to MediaRecoder's surface for each frame.

You can switch to each camera by changing render object. You can also render both images in same video using alpha-blend, transform, scaling, etc. by 30fps
