What "continuous jpeg frames"? The only 'continuous' frames in the viewfinder are the preview frames, and those are not jpeg: they are YCrCb at 15 fps. Unless you make your own jpeg out of YCrBb, but why bother? You need a Bitmap for the Canvas for SurfaceView anyway: you may as well use RGB or ARGB instead of JPEG (see Bitmap.Config). Then no conversion is necessary. In fact, it is not useful with a Canvas, since it is not among the formats listed on Bitmap.Config.
Now if you are willing to live with the Camera object's preview, you can let it display the frames, but capture the frames also for your own processing using the Camera.setPreviewCallback() method to register your own handler for each frame. I realize this does not do exactly what you asked for, but it is a lot less work than what you are proposing, and gives you much of what you probably really need.
