Ptr<VideoReader> cv::cudacodec::createVideoReader | ( | const String & | filename | ) |
#include <opencv2/cudacodec.hpp>
Creates video reader.
filename | Name of the input video file. |
FFMPEG is used to read videos. User can implement own demultiplexing with cudacodec::RawVideoSource
Ptr<VideoReader> cv::cudacodec::createVideoReader | ( | const Ptr< RawVideoSource > & | source | ) |
#include <opencv2/cudacodec.hpp>
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
source | RAW video source implemented by user. |
Ptr<VideoWriter> cv::cudacodec::createVideoWriter | ( | const String & | fileName, |
Size | frameSize, | ||
double | fps, | ||
SurfaceFormat | format = SF_BGR |
||
) |
#include <opencv2/cudacodec.hpp>
Creates video writer.
fileName | Name of the output video file. Only AVI file format is supported. |
frameSize | Size of the input video frames. |
fps | Framerate of the created video stream. |
format | Surface format of input frames ( SF_UYVY , SF_YUY2 , SF_YV12 , SF_NV12 , SF_IYUV , SF_BGR or SF_GRAY). BGR or gray frames will be converted to YV12 format before encoding, frames with other formats will be used as is. |
The constructors initialize video writer. FFMPEG is used to write videos. User can implement own multiplexing with cudacodec::EncoderCallBack .
