avpicture_fill
Overview
Defined in avcodec.h
Fill in the AVPicture fields.
The fields of the given AVPicture are filled in by using the 'ptr' address which points to the image data buffer. Depending on the specified picture format, one or multiple image data pointers and line sizes will be set.
If a planar format is specified, several pointers will be set pointing to the different picture planes and the line sizes of the different planes will be stored in the lines_sizes array.
int avpicture_fill(AVPicture *picture, uint8_t *ptr, int pix_fmt, int width, int height);
