public FileFormatBodyC

StringC vName;

Variant name.

FileFormatV4LBodyC(const StringC & vName)

Constructor.

const type_info & ProbeLoad(IStreamC & in,const type_info & obj_type) const

Is stream in std stream format ?

const type_info & ProbeLoad(const StringC & filename,IStreamC & in,const type_info & obj_type) const

Probe for load.

const type_info & ProbeSave(const StringC & filename,const type_info & obj_type,bool forceFormat) const

Probe for Save.

DPIPortBaseC CreateInput(IStreamC & in,const type_info & obj_type) const

Create a input port for loading.
This creates a plain V4L stream. Will create an Invalid port if not supported.

DPOPortBaseC CreateOutput(OStreamC & out,const type_info & obj_type) const

Create a output port for saving.
This creates a plain V4L stream. Will create an Invalid port if not supported.

DPIPortBaseC CreateInput(const StringC & filename,const type_info & obj_type) const

Create a input port for loading from file 'filename'.
Will create an Invalid port if not supported.

DPOPortBaseC CreateOutput(const StringC & filename,const type_info & obj_type) const

Create a output port for saving to file 'filename'..
Will create an Invalid port if not supported.

const type_info & DefaultType() const

Get prefered IO type.

IntT Priority() const

Find the priority of the format. the higher the better.
Default is zero, this is better than the default (streams.)

bool IsStream() const

Test if format is a fully streamable.
i.e. check if you can read/write more than object object.

bool CheckRGB(int fd,struct video_picture & pic) const

bool CheckYUV(int fd,struct video_picture & pic) const

bool CheckYUV422(int fd,struct video_picture & pic) const

bool CheckGREY(int fd,struct video_picture & pic) const

const StringC & Name() const

Name of file format.

const StringC & Description() const

Description of fileformat.

const type_info & ProbeLoad(IStreamC & in,const type_info & obj_type) const

Is stream in this format ?
This asks the question: Can stream 'in' be loaded into object 'obj_type' ? typeid(void) == no, otherwise returns the prefered load type.

const type_info & ProbeLoad(const StringC & filename,IStreamC & in,const type_info & obj_type) const

Is stream in this format ?
This asks the question: Can stream 'in' be loaded into object 'obj_type' ? If used with a empty filename asks: Can load this type of object ? typeid(void) == no, otherwise returns the prefered load type.

const type_info & ProbeLoad(const StringC & filename,const type_info & obj_type) const

Is stream in this format ?
This asks the question: Can stream 'in' be loaded into object 'obj_type' ? If used with a empty filename asks: Can load this type of object ? typeid(void) == no, otherwise returns the prefered load type.

const type_info & ProbeLoad(const type_info & obj_type) const

Is stream in this format ?
Alias for ProbeLoad("",IStreamC(),obj_type); typeid(void) == no, otherwise returns the prefered load type.

const type_info & ProbeSave(const StringC & filename,const type_info & obj_type,bool forceFormat) const

Is Filename in this format ?
This asks the question: Can file 'filename' be saved with object 'obj_type' ? If used with a empty filename asks: Can save this type of object ? typeid(void) == no, otherwise returns the prefered save type.

const type_info & ProbeSave(const type_info & obj_type) const

Alias for ProbeSave("",IStreamC(),obj_type);
typeid(void) == no, otherwise returns the prefered save type.

DPIPortBaseC CreateInput(const StringC & filename,const type_info & obj_type) const

Create a input port for loading from file 'filename'.
Will create an Invalid port if not supported.

The default version of this functions opens the file and passes the stream to CreateInput(IStreamC ....)

DPOPortBaseC CreateOutput(const StringC & filename,const type_info & obj_type) const

Create a output port for saving to file 'filename'..
Will create an Invalid port if not supported.

The default version of this functions opens the file and passes the stream to CreateOutput(OStreamC ....)

DPIPortBaseC CreateInput(IStreamC & in,const type_info & obj_type) const

Create a input port for loading from stream 'in'.
Will create an Invalid port if not supported.

DPOPortBaseC CreateOutput(OStreamC & out,const type_info & obj_type) const

Create a output port for saving to stream 'out'.
Will create an Invalid port if not supported.

const type_info & DefaultType() const

Get prefered IO type.
This specifies the native class for representing the data in a file.

typeid(void) if none, indicates an indirect driver.

IntT Priority() const

Find the priority of the format. the higher the better.
Default is zero.

bool IsStream() const

Test if format is a fully streamable.
i.e. check if you can read/write more than object object. (Default value of this function is true).

static bool ReadString(IStreamC & is,StringC & buff,UIntT maxLen = 256)

read a string form the input.
returns false if the stream contains non text charators or is longer than the given length. This will also restore the file read position after the read.

static StringC ExtractDevice(const StringC & nm)

Get the device from the full name.
For use in '@X:' style device formats.

static StringC ExtractParams(const StringC & nm)

Get the device from the full name.
For use in '@X:' style device formats.
