Any way to get preview frames while recording video?

I want to stream video to a server and record it on the device at the same time.

If I'm not recording the video I can use Camera.onPreviewCallback where I get the preview data as a byte array and I send the data to the server.

When I start recording though (I'm using MediaRecorder) then onPreviewCallback is called no more.

How can I still obtain the frames from the camera?

Getting preview callbacks at the same time as recording video is not currently supported by the camera API.

On the latest Android versions, you could use a SurfaceTexture for your preview output, and read the textures back from the GPU to send to your server, instead of using the preview callbacks.
