Compute what kind of losses will occur when converting from one specific
pixel format to another.
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. These losses can involve loss of chroma, but also loss of
resolution, loss of color depth, loss due to the color space conversion, loss
of the alpha bits or loss due to color quantization.
av_get_fix_fmt_loss() informs you about the various types of losses
which will occur when converting from one pixel format to another.
@paramin dst_pix_fmt destination pixel format
@paramin src_pix_fmt source pixel format
@paramin has_alpha Whether the source pixel format alpha channel is used.
@return Combination of flags informing you what kind of losses will occur
(maximum loss for an invalid dst_pix_fmt).
