Probably not; the typical use, a "quasi standard", is to have exactly the  
hyphen only as input file name.

If you have raw YUV input, you really need to provide the image dimensions  
(width × height), possibly even the picture type (e.g. FourCC, like "I420"  
or "YV12" for 4:2:0, or possibly "YUY2" if 4:2:2 is supported some day).

So you may use an additional "-y4m" option instead of all the required  
options for raw YUV, to indicate that the piped input is YUV4MPEG instead  
of raw YUV.
