Member Function Documentation

format()

virtual FormatInfo cv::cudacodec::RawVideoSource::format ( ) const

pure virtual

Returns information about video file format.

get()

virtual bool cv::cudacodec::RawVideoSource::get ( const int  propertyId, double &  propertyVal  ) const

pure virtual

Retrieves the specified property used by the VideoSource.

Parameters

propertyId	Property identifier from cv::VideoCaptureProperties (eg. cv::CAP_PROP_POS_MSEC, cv::CAP_PROP_POS_FRAMES, ...) or one from Additional flags for video I/O API backends.
propertyVal	Value for the specified property.

Returns

true unless the property is unset set or not supported.

getExtraData()

virtual void cv::cudacodec::RawVideoSource::getExtraData ( cv::Mat &  extraData ) const

pure virtual

Returns any extra data associated with the video source.

Parameters

extraData

1D cv::Mat containing the extra data if it exists.

getNextPacket()

virtual bool cv::cudacodec::RawVideoSource::getNextPacket ( unsigned char **  data, size_t *  size  )

pure virtual

Returns next packet with RAW video frame.

Parameters

data	Pointer to frame data.
size	Size in bytes of current frame.

lastPacketContainsKeyFrame()

virtual bool cv::cudacodec::RawVideoSource::lastPacketContainsKeyFrame ( ) const

inlinevirtual

Returns true if the last packet contained a key frame.

updateFormat()

virtual void cv::cudacodec::RawVideoSource::updateFormat ( const FormatInfo &  videoFormat )

pure virtual

Updates the coded width and height inside format.
