[MPlayer-dev-eng] video rate in client/server application

[Daniel Sadoc Menasche]

Hi,

Thanks a lot. In fact I´m using mpeg.  The camera which I´m using
generates mpeg data.  As soon as the server sends a video block to the
client, I´m also making a copy of the sent video on the server, in a file
called video_sent.mpg.

When I run

./client | (mplayer -)

the video plays slowly.

But when I run

mplayer video_sent.mpg

the video plays correctly.

How may I know where is the problem? How may I verify if the enconder I´m 
using is generating bad data?

Is it possible that the problem relies on the communication between the 
client program and mplayer?

Regards,
Daniel Sadoc
