Detailed Description

Interface for video demultiplexing. :

User can implement own demultiplexing by implementing this interface.

Constructor & Destructor Documentation

◆ ~RawVideoSource()

virtual cv::cudacodec::RawVideoSource::~RawVideoSource ( )
inlinevirtual

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
propertyIdProperty 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.
propertyValValue 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
extraData1D 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
dataPointer to frame data.
sizeSize 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.
