Playing Movies

[Master of Reality]

Im not sure what the problem is with my video. I try to play an mpeg with mplayer (or noatun, xine, etc) and the output is just greenish lines and such, with audio (i think). It worked in the past so but i recall it also doing this before a long time ago. Any ideas what the problem is?

[Tux]

Got all the codecs installed? win32, xanim, Real etc?

Also have you tried using differnt video outputs? (-vo in mplayer)

[Linux Frank]

Are you sure it is an Mpeg? that particular problem (audio and a green screen) is often indicative of a badly encoded AVI - or an AVI newer than can be supported by currently installed codecs. Mplayer has a seperate package that includes many of the codecs you would need, was this installed?

[Master of Reality]

ahhh... i think that may be how i fixed it last time. I shall install the mplayer codecs pack.

[Master of Reality]

erm.... does anyone know where to put the codecs? i dont have a /usr/local/lib/codecs like the mplayer documentation mentions.

Maybe i should install mplayer from source instead of a tgz package.

[Tux]

/usr/local/lib/win32
and symobolically link /usr/lib/win32 to the above (or vice versa)

[Master of Reality]

alright the sound didnt work before but now it does.. the codec does load.. (avi) but i get some errors... here they are:

anyone know what this means... i would suspect the error where it says couldnt open /dev/mga_vid (which i have no idea what that means)

Does adding "-vo x11" to the command line give you video?

[Master of Reality]

yes, yes it does......... what'd i do?
oh... so it was trying to use some sort of other video.. instead of X11.
I see

[Void Main]

Precisely. It is defaulting to a video device that you don't have. x11 usually works on everything although it is about the least efficient. Usually "sdl" or "xv" are better choices if your system supports them. You can set this as the default in your config file. The easiest way to do that is just run "gmplayer" and right click on it and change the video output in the options.

[Master of Reality]

hmmm any ideas as to how to make the sound play at the same time as the movie. There is about a 4 or 5 second difference. I tried ALSA and OSS drivers which both do the same. And i dont have the others.

[Void Main]

Never had that problem. What format is the movie in and how fast is your machine?

[Tux]

You often get that A/V sync problem with stuff encoded with older divx and xvid codecs. The solution is to ge t mplayer to compensate.

You could to this on the command line like this:

(g)mplayer video.avi -ao alsa9 -af delay 1.2

This would play video.avi, output audio to ALSA and delay audio by 1.2 seconds from video. You can also use a -ve value. These setting can also be set in gmplayers controls.

[Tux]

Another thing:

The +/- keys adjust audio sync up and down 0.1s each press on the fly, that can be more useful than guessing values.

[Master of Reality]

ill try the delay dealy.

It was avi and mpg and my machine is 96MB RAM, 32MB video and 1GHz Duron
