[solved] mplayer - don't play, only show info?

chochem · 2008-09-22 12:24:00

I'm trying to get maplyer mplayer/mencoder to just show me what streams are available in a file. There's a lot of useful info reported when I start a file simply typing mplayer file name but I can't find the option to a) display specific info and b) not to start playing the file. Any help?

I'm sorry? I can start mplayer playing and then inspect a log? I don't quite follow you...

We need to see what mplayer actually outputs.

Oh, okay. Here's starting an OGM file with two audio tracks and one embedded subititle stream:

There isn't really a problem with the playback and all I Have to do is stop it, go back over the output and add "-aid 1" and "-sid 0" as arguments and everything plays nciely. It 's just that I'd like to script it for ease of use.

Allan · 2008-09-22 12:58:33

Not a script but some short cut keys that are good:

- To change subtitles j
- To switch audio track #

Is this an mplayer build from svn?

chochem · 2008-09-22 13:04:22

Ah, yes.. The audio switching didn't work with the OGM file but I can see now that it works with stuff like matroska.

No, from the extra repos.

EDIT: Hang on, this is weird. Yaourt says I've got two versions installed, the one from extra AND the one from the AUR both reported as being 1.0rc2-6...

hmm now you should say I'm sorry:)

try to change video output driver:

$mplayer -vo help

skottish · 2008-09-22 15:59:35

A very hackish way to get the only info:

mplayer -endpos 0 <YOUR_MOVIE>

The endpos switch tells Mplayer how long to play for. With this switch, it will start and stop immediately.

chochem · 2008-09-22 18:36:27

Thanks everybody... Kind of a silly request, really but hey. Mashing skottish's and piotrk's suggestions together, I came up with:

mplayer -endpos 0 -vo null -ao null <file name>

which cancels all outputs and stops 'playing' immidiately. Still, seems strange that you have to hack your way to this....
