- * @deprecated use avcodec_find_best_pix_fmt2() instead.

- * Find the best pixel format to convert to given a certain source pixel
- * format.  When converting from one pixel format to another, information loss
- * may occur.  For example, when converting from RGB24 to GRAY, the color
- * information will be lost. Similarly, other losses occur when converting from
- * some formats to other formats. avcodec_find_best_pix_fmt() searches which of
- * the given pixel formats should be used to suffer the least amount of loss.
- * The pixel formats from which it chooses one, are determined by the
- * pix_fmt_mask parameter.
- *
- * @code
- * src_pix_fmt = AV_PIX_FMT_YUV420P;
- * pix_fmt_mask = (1 << AV_PIX_FMT_YUV422P) || (1 << AV_PIX_FMT_RGB24);
