Detailed Description

Command line program to capture a camera video stream and encode it to file. Also optionally display a preview/viewfinder of current camera input.

Date: 28th Feb 2013 : James Hughes

Description

3 components are created; camera, preview and video encoder. Camera component has three ports, preview, video and stills. This program connects preview and stills to the preview and video encoder. Using mmal we don't need to worry about buffers between these components, but we do need to handle buffers from the encoder, which are simply written straight to the file in the requisite buffer callback.

We use the RaspiCamControl code to handle the specific camera settings. We use the RaspiPreview code to handle the (generic) preview window

main

int mmal_status_to_int ( MMAL_STATUS_T status )

Convert a MMAL status return value to a simple boolean of success ALso displays a fault if code is not success

Parameters

status The error code to convert

Returns: 0 if status is sucess, 1 otherwise
