@item skip_alpha @var{integer} (@emph{decoding,video})
|

causes alpha plane not to be decoded, like "gray" which skips chroma.
|
||||
Set to 1 to disable processing alpha (transparency). This works like the
|
||||
@samp{gray} flag in the @option{flags} option which skips chroma information
|
||||
instead of alpha. Default is 0.
