Hi all, I have been trying to play a video file in *.dat format, whatever the dat extension means. The file plays well in windows. When i try to play it using mplayer it gives the following message and quits. MPlayer 1.0pre6-3.3.3 (C) 2000-2004 MPlayer Team CPU: Intel Pentium 4/Xeon/Celeron Northwood (Family: 8, Stepping: 4) Detected cache-line size is 64 bytes CPUflags: MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled with runtime CPU detection - WARNING - this is not optimal! To get best performance, recompile MPlayer with --disable-runtime-cpudetection. Linux RTC init error in ioctl (rtc_irqp_set 1024): Permission denied Try adding "echo 1024 > /proc/sys/dev/rtc/max-user-freq" to your system startup scripts. Opening joystick device /dev/input/js0 Can't open joystick device /dev/input/js0 : No such device Can't init input joystick Setting up LIRC support... mplayer: could not connect to socket mplayer: Permission denied Failed to open LIRC support. You will not be able to use your remote control. Playing avseq01.dat. Seek failed Exiting... (End of file) I installed Mplayer from Pacman's site using Synaptic. So I guess there shouldn't be any problems with the codecs. Then I tried to play the same file using Xine. This is one of the messages it gives. I am not putting the whole lines. I think this is the most relevant one. It says, 'There is no demuxer plugin available ... means file format not recognised' I press More on the window and get this xine : couldn't find demux for >avseq01.dat< among other messager. I say file * on the command line and it gives this: avseq01.dat: ERROR: cannot read `avseq01.dat' (Input/output error) Anyone faced this before. Anyhelp is appreciated. And one more thing is that I am able to play some wmv files but not others. Regards, Chaitanya. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
