/**
* @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);
* dst_pix_fmt = avcodec_find_best_pix_fmt(pix_fmt_mask, src_pix_fmt, alpha, &loss);
* @endcode
*
* @param[in] pix_fmt_mask bitmask determining which pixel format to choose from
* @param[in] src_pix_fmt source pixel format
* @param[in] has_alpha Whether the source pixel format alpha channel is used.
* @param[out] loss_ptr Combination of flags informing you what kind of losses will occur.
* @return The best pixel format to convert to or -1 if none was found.
