[MPlayer-users] pipe and directly.

[Yoshihiro Ueda]

When occasioning to output the file through the pipe and outputting 
it directly, operation is different. 
When the pipe is passed, severalM of the starts does the output 
failure. 

However, there is no failure at the direct output and it is possible to output it. 

Perhaps, though it seems that the file header is related
Is the one what doing very this difference that is a pipe it, there no failure, 
and can output?

Can you do in the setting of the command option etc.
My best regards.
