Ok, that sounds crazy in the subject 'cause all mplayer users know you can just run:
Code:

mplayer

then the file name and it will run the file.

But due to the speed of my computer (what there is of it) I have given a lot of parameters to mplayer and I seem to keep adding more:
Code:

mplayer -vo x11 -zoom -aspect 4:3 filename.avi


I'm wondering how to set up a bash script that has all my parameters then allows me to run the file I want. For example, if the script were titled 'video-play' it would something like:
Code:

video-play filename.avi


As I write it now I don't know the one key parts of the script, the part that will allow me to input data after the script, to run it. So I write the bash for mplayer with all the parameters, without the file I want to run, but it of course kicks back even if I type in the file I want afterwards.

Would one of you bash/script wizards tell me how to do this, pretty please? Wink

$1 is for args (filename)

Code:

#!/bin/sh

DEF="-vo x11 -zoom -aspect 4:3"
mplayer  ${DEF} "$1"

Very Happy Hello,
Using a variable as above wont solve the filename issue, but this will..
At the end of your script, add
"$@"
including the quotes..
EX: mplayer -vo x11 -zoom -aspect 4:3 "$@"
Then put the script on the desktop, and drop your files on it....

Perfect, jpeps, thank you! That is all I needed...
I tried yours but for some reason it kicks back that -vo isn't a recognized command...something about my spacing or something, I'm sure, but this worked great:
Code:

#!/bin/bash
mplayer -vo x11 -zoom -nortc -nocache -lavdopts fast -aspect 4:3 "$1"

save the script in whatever name I want, in this case video-play, then I run whatever file I want with it like this:
Code:

video-play moviefile.avi

and it plays the movie great! Now I can add parameters as I want without having to remember every last little one. Thanks again. Cool

Since I kinda like the definition stuff being seperate, the script now looks like this (added that last mod from jpeps and will probably continue to make changes in mplayer definitions until I get the format I want):
Code:

#!/bin/bash
DEF="-vo xv -zoom -nortc -nocache -lavdopts fast -aspect 4:3"
mplayer ${DEF} "$@"


Thanks!

I could be mistaken. I think we needed a loop or something like it to play the second and third videos. Depending I suppose on how the script is run.

Code:
#!/bin/bash

DEF="-vo xv -zoom -nortc -nocache -lavdopts fast -aspect 4:3"

for i in "$@" ; do
    mplayer ${DEF} "$i"
done

An even simper way would be to add to your ~/.bashrc:
Code:
alias mplayer='mplayer -vo xv -zoom -nortc -nocache -lavdopts fast -aspect 4:3'

why not one more option so you see there are many ways to get there


edit this file

/usr/local/bin/defaultmediaplayer

to look like this

Code:
#!/bin/bash
#exec gxineshell "$@"
#exec /usr/bin/gmplayer -msglevel all=-1 "$@" &
#exec vlc -vvv "$@"
exec mplayer -vo xv -zoom -nortc -nocache -lavdopts fast -aspect 4:3 "$@"

Hi steve_s

I don't know about many mplayer options but I do know you can at least put sound and video options in your ~/.mplayer/config file. (I'm fairly sure you can put others in there too). It should be faster than bash.
eg: vo=x11

This isn't a bash script and it is overkill in the extreme.
FWIW here is a BaCon program for video-play.
