2021-07-22cam: options: Avoid copies of OptionvValue and KeyValueParser::OptionsLaurent Pinchart
The OptionValue toKeyValues() and toArray() functions return a copy of the values. This is unnecessary, and can cause use-after-free issues when taking references to the return values. Return references instead to optimize the implementation and avoid issues. The behaviour of the two functions is now undefined in case of an option type mismatch. The current implementation catches this with an assertion.

2021-07-22cam: stream_options: Use OptionValue::empty() to test if option is setLaurent Pinchart
The roles() and updateConfiguration() functions check if the OptStream OptionValue they receive is empty by first casting it to an array. To prepare for the toArray() function not allowing such a cast when the option value is empty, test if the option value is empty instead.

2021-07-22cam: options: Drop some OptionValue cast operatorsLaurent Pinchart
While OptionValue cast operators to int and std::string allow useful shortcut syntaxes, the cast operators to KeyValueParser::Options and std::vector<OptionValue> are less useful. A an explicit static_cast call would be more cumbersome to write than an explicit .toKeyValues() or toArray(), and implicit cast hide too much of what's going on. Drop those two cast operators, and replace the only implicit cast occurrence with .toKeyValues(). While at it, drop the local opts variable in StreamKeyValueParser::roles() as it isn't used.

2021-07-22cam: options: Support parent-child relationship between optionsLaurent Pinchart
Add support for creating a tree-based hieararchy of options instead of a flat list. This is useful to support options that need to be interpreted in the context of a particular occurrence of an array option. The usage text automatically documents the options in their corresponding context: Options: -c, --camera camera ... Specify which camera to operate on, by id or by index -h, --help Display this help message -I, --info Display information about stream(s) -l, --list List all cameras --list-controls List cameras controls -p, --list-properties List cameras properties -m, --monitor Monitor for hotplug and unplug camera events Options valid in the context of --camera: -C, --capture[=count] Capture until interrupted by user or until <count> frames captured -F, --file[=filename] Write captured frames to disk If the file name ends with a '/', it sets the directory in which to write files, using the default file name. Otherwise it sets the full file path and name. The first '#' character in the file name is expanded to the camera index, stream name and frame sequence number. The default file name is 'frame-#.bin'. -s, --stream key=value[,key=value,...] ... Set configuration of a camera stream height=integer Height in pixels pixelformat=string Pixel format name role=string Role for the stream (viewfinder, video, still, raw) width=integer Width in pixels --strict-formats Do not allow requested stream format(s) to be adjusted --metadata Print the metadata for completed requests Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2021-07-22cam: options: Move key string left in usage() for key-value parserLaurent Pinchart
