MPlayer/MEncoder Tips and Tricks

[corra]

Hi,
congratulations for this nice how-to...I'd like to know if it's possible to jump from a track to another (by keyboard) when you listen to an audio cd with mplayer. I read the manual but ->, -<, Pg up and pg down are what I'm looking for...
Thank you,
Corra

If you play audio cd like this:

Code: Select all

 $ mplayer -identify cdda://

it will list numbers of track and spew out information about each track (though not the title). From man mplayer:

Code: Select all

! and @
                   Seek to the beginning of the previous/next chapter

So holding down the SHIFT key and pressing @ will make mplayer jump to next track, while holding SHIFT and pressing ! will make it jump to previous.

It doesn't work...here is what happens when I press @:

Code: Select all

It worked fine with my svn mplayer however the debian-multimedia's mplayer seems to be struck. I'm not sure what's the difference in the mplayer I compiled and the one from debian repository.

[RoyFokker]

Unfortunately due to the inflexible linux sound implementation if you want to use mplayer to watch a video only and listen to audio only in another program, the audio will mix together from both apps. If you mute the PCM level on mplayer it will mute on every other running program as well.

I have found the commandline option:
mplayer -ao 0
is useful so you can listen to mp3 or flash audio with other programs while watching a muted video in mplayer.

Good post!
re the debian-multimedia key, this is the key, the preceding characters are unnecessary:
# gpg --keyserver pgp.mit.edu --recv-keys 07DC563D1F41B907
# gpg --armor --export 1F41B907 | apt-key add -

You can also use this pgp url:
gpg --keyserver hkp://wwwkeys.eu.pgp.net --recv-keys 1F41B907
gpg --armor --export 1F41B907 | apt-key add

Sorry for waking up this old thread but it fits what I need to know:
When adding a repository, it asks for a key How do you know what that key is? Besides that What does that key mean?

Thanks in advance,

Great thread. Is it worth converting from Totem to Mplayer?

Great thread. Is it worth converting from Totem to Mplayer?

I don't know - it's up to you. You could always keep Totem, but it could get conflicting especially when playing the plugins in Iceweasel/Firefox. In one of my installation that also included full Gnome desktop that has Totem by default, I simply make sym linksof mplayer plugins in /usr/lib/mozilla/plugins/ to /usr/lib/iceweasel/plugins/ for example:

Code: Select all

ln -s /usr/lib/mozilla/plugins/mplayerplug-in-dvx.so /usr/lib/iceweasel/plugins/

Make sym links for all mplayer plugins *.so files. So when I start up iceweasel, it'll be mplayer plugin that it's using not totem.

When I first tried mplayer, several years ago, I just couldn't get it working well. I tried several different systems then and settled on Totem. Now, however, I'm wondering if mplayer has caught up with or passed Totem. Is there any sign that Debian might switch from default Totem?

Not in standard Debian installation, at least there is no media player installed by default. If you install desktop like Gnome, Totem will be installed as one of dependencies. I install just barebone system with multimedia stuffs from Debian-multimedia repository. So far MPlayer (and Mencoder) never gave me any problem. It is highly versatile, stable and does about everything for me.

I found a couple of interesting tips about mplayer here:
http://xt7-player.sourceforge.net/xt7fo ... p?f=5&t=81
http://xt7-player.sourceforge.net/xt7fo ... p?f=5&t=10

In particular about audio options tuning, channel mapping, and realtime audio normalization using ladspa, impressive!

Thanks. It's quite interesting especially for anyone who want to map 5.1 sound to 2.0 speaker system. As usual, mplayer by itself has options like pan and channels.

See, Chapter 4. Advanced audio usage in MPlayer's online documentation:

http://www.mplayerhq.hu/DOCS/HTML-singl ... l#advaudio

Btw, as an example to play 5.1 sound from first title of a DVD film in a 2.0 speaker system using the pan filter options given in the link above:

Code: Select all

mplayer dvd://1 -channels 6 -af pan=2:0.5:0:0:0.5:0.5:0:0:0.5:1:1:0.5:0.5

[L4m3b0yz]

I'm reading the man page right now, and the pan filter syntax is driving me crazy, Not even that xt7-player has a gui for it, but i think i will succeed .

...Or maybe it's time to buy a 5.1 system...

This is an old post, but I'll post here anyway in case some newbie search for answer.

I am a pretty new newbie. Had been trying for a few days to get mplayer working. I cannot follow the instruction here, e.g., I don't know where is "my path to video". Search LQ and mplayer.org and can't get it to work.

What I did to make it work was this:

In gnome desktop, add media to sources.list as stated in post 1.
Using Synaptic package manager, check (search) if mplayer has been installed, if not mark and install it.
Again check if w64codec or w32codec (depending on your system) has been installed, if not install it.
Again check if smplayer has been installed, if not, install it. This is the front end to mplayer (a gui interface).
Next, execute smplayer (applications->sound & video->smplayer
Next option->preferences-general tab-video In this menu here choose what you wish to use. I use vx since it has hardware acceleration. For audio, I use OSS (I use alsamixer to configure my sound)
Next, under the video tab I checked all options, but for some dvd's postprocessing does more bad than good, if so, uncheck it.
Next under options-drives select cd devices, I use /dev/cdrom for both cd and dvd.

That is all, should work like a charm.

"my path to video" is actually "your path to video".

I see that debian-multimedia has added mplayer-mt (multicore playback for h.264 and mpeg2 codecs) to the testing and unstable repository. I tried a backport of the deb on 64 bit to a "safe" Lenny version (no restricted encoding ability, such as h.264 or mpeg4; plays back those files just fine, which is OK with the patent holders, more business for their content)

I did add some safe opensource libraries to build against:

libvdpau1 from debian-multimedia stable for accelerated hardware video for newer nvidia cards.
libopencore-amrnb and -amrwb from Squeeze, these can be directly installed into Lenny without any other updating needed.
libasound2 from lenny-backports, the Lenny version is just too old to work with the latest source code.

If anyone is interested, I could build a 32 bit version, too, and put the debs, plus the other deb files, into a zip archive. That way, you could just extract the archive and install them all with

dpkg -i *.deb
apt-get -f install

Edit: I could throw the latest SMplayer front-end deb builds from svn in there while I'm at it...
