ffmpegInitialise()

void ffmpegInitialise

(

)

Initialise the ffmpeg library.

formatArray()

int formatArray	(	NDArray *	pArray,
		asynUser *	pasynUser,
		AVFrame *	inPicture,
		struct SwsContext **	pCtx,
		AVCodecContext *	c,
		AVFrame *	scPicture
	)

Format an NDArray as an AVFrame using the codec context c.

Use inPicture to wrap the data in pArray, use swscale to convert it to scPicture using the output parameters stored in c. Special case for gray8 -> YUVx, can use the data as is and add a neutral array for the colour info.
