2019-02-25cam: free allocated buffers when done capturingNiklas Söderlund
The allocated buffers needs to be freed once the application is done with them. Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2019-02-25cam: fix return type of configureStreams()Niklas Söderlund
The only caller of configureStreams() stores its return value as an int and not bool. This is confusing and also prevents the (possibly) different error codes returned by Camera::configureStreams() to be propagated inside the cam tool. Fix this by changing the return type to int and propagate the return value from the camera.

2019-02-06cam: Add option to write raw frames to diskNiklas Söderlund

2019-02-06cam: Add capture operationNiklas Söderlund
Add an option to capture frames from a camera and keep it running until the user terminates by sending SIGINT.

2019-02-01cam: Add --format option to configure a streamNiklas Söderlund
Add an option to configure the first stream of a camera from an argument with options and parse the width, height and pixel format from that list. The pixel format is still specified as a integer which should correspond to the kernels FOURCC identifiers. Going forward this should be turned into a string representation and the cam parser should translate between the two.

2019-02-01cam: options: Add option type handling to options parserLaurent Pinchart
Extend the options parser with support for option types. All options must now specify the type of their argument, and the parser automatically parses the argument and handles errors internally. Available types are none, integer or string. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2019-02-01cam: options: Move enum OptionArgumentNiklas Söderlund
The enumeration of the different possibilities for arguments can be used by other parser then OptionsParser. Move it outside the class to make it ready to be used by other parsers.

2019-01-25cam: Add event loopLaurent Pinchart
Add a simple event loop to the cam application and use it in the main() function, with an example of how to handle SIGINT to gracefully stop the loop. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2019-01-22cam: options: Don't implement move semantics for OptionsParser::OptionsLaurent Pinchart
The compiler creates a move constructor automatically when none is supplied, and it does the right thing by default in this case. Using std::move() inside the function prevents the compiler from doing return value optimization and actually hinders performances. Using std::move() in the caller is unnecessary, the move constructor is used automatically by the compiler. For all these reasons remove the tentative optimization that resulted in worse performances and worse code.
