[MPlayer-users] piping with | and stdin, mplayer -

[Konstantin Kletschke]

Hi there!

For benchmark purposes I sometimes cat an video file into netcat and on
another machiene I cat it with netcat into an |mplayer -
On most videos this is working and is the equivalent to a
local "cat bla.avi|mplayer -".
But on some videos that is not working :(

It fills up its cache and than does nothing anymore. Nothing obvious,
don't know what is going under the hood, though...

With -nocache it does not fill up the cache of course

Playing -.
Reading from stdin...
AVI file format detected.

[after a while]

AVI: Missing video stream!? Contact the author, it may be a bug :(

Exiting... (End of file)

The file is:
X-Men.2.german.DVDrip.DivX-5.1.AC3-5.1.CD1.KM.avi: RIFF

PLaying around I tried to create another one, with it it may work:

mencoder -ovc xvid X-Men.2.german.DVDrip.DivX-5.1.AC3-5.1.CD1.KM.avi
-oac lavc -o X2-1v2.xvid -xvidencopts pass=1

But that doesn't work neither.

For example xine does it, but that is not an alternative, it is slow
and crashes very often...
