int NDFileOpenMode_t
Definition: NDPluginFile.h:17
N-dimensional array class; each array has a set of dimensions, a data type, pointer to data,...
Definition: NDArray.h:99
Base class for NDArray file writing plugins; actual file writing plugins inherit from this class.
Definition: NDPluginFile.h:28
Writes NDArrays to a ffmpeg file.
Definition: ffmpegFile.h:22
int ffmpegFileFPS
Definition: ffmpegFile.h:37
int ffmpegFileHeight
Definition: ffmpegFile.h:38
virtual asynStatus readFile(NDArray **pArray)
Reads single NDArray from a ffmpeg file; NOT CURRENTLY IMPLEMENTED.
Definition: ffmpegFile.cpp:288
virtual asynStatus writeFloat64(asynUser *pasynUser, epicsFloat64 value)
Called when asyn clients call pasynFloat64->write().

Definition: ffmpegFile.h:35
ffmpegFile(const char *portName, int queueSize, int blockingCallbacks, const char *NDArrayPort, int NDArrayAddr, int priority, int stackSize)
Constructor for ffmpegFile; all parameters are simply passed to NDPluginFile::NDPluginFile.
Definition: ffmpegFile.cpp:387
virtual asynStatus closeFile()
Closes the ffmpeg file.
Definition: ffmpegFile.cpp:297
virtual asynStatus openFile(const char *fileName, NDFileOpenMode_t openMode, NDArray *pArray)
Opens an FFMPEG file.
Definition: ffmpegFile.cpp:19
int ffmpegFileWidth
Definition: ffmpegFile.h:39
virtual asynStatus writeFile(NDArray *pArray)
Writes single NDArray to the ffmpeg file.
