MenCoder, FFMPEG, VP7 codec troubles

[iSlayter]

Hello everybody.

I've got a problem. On my web-server stores 250 Gb of videos encoded with codec VP7.

Now I must:

• Re-encode videos with xvid.
• Take screenshots in GIF format from 10 frames.
• Place watermark from transperent GIF

Initially I wanna use FFMPEG, but when I install it I get error while encoding because he doesn't understand input codec. And also I know that getting screenshots is very slowly in FFMPEG (for screenshot at 30 minute it takes 52 seconds). So I decide to try Mplayer. But he is not support watermarks at all.

AFAIR VP7 is part of Intel Indeo codecs which versions above 3.0 doesn't supported in any opensource project.

Then I find rather interesting lines at http://www.mplayerhq.hu/design7/info.html

# Intel Indeo3 (3.1, 3.2)
# Intel Indeo 4.1 and 5.0 (using x86 DLL or XAnim codecs)

Then when I install mplayer and try to use it I've got another error:

What's wrong with it? (((

Have you installed the w32codecs package from the medibuntu repository?

[cordel]

My guess is that you have not installed the required dll as it lists. This will likely need to be run under wine as well to have use of the dll or run on ms machine. Might check the mplayerhq.hu faq, I seen a hint about this there I think.

Have you installed the w32codecs package from the medibuntu repository?

Sorry, I'm very newbie
I try to do it this way:

root@Ubuntu-804-hardy-LTS-64-minimal:~# apt-get install w32codecs
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package w32codecs is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package w32codecs has no installation candidate

How I can change repository server on other from ssh?
Before tuning server I already use Ubuntu as a Desktop but install everything with synaptic. Not manually

[geirha]

The medibuntu link I provided has instructions on how to add the medibuntu repository (Repository Howto). After it is added, running apt-get install w32codecs should work as expected.

Thanks! I try to follow manual at link you provided but now I get same error.

BTW how can I get list of packages by PCRE (for example "/w32codesc(.*)/i"?

You need to run

sudo apt-get update
# or
sudo aptitude update

To download the package lists first. Forgot to mention that.

BTW how can I get list of packages by PCRE (for example "/w32codesc(.*)/i"?

aptitude search accepts regular expressions

aptitude search '^w[0-9]+codecs$'

This is documented in /usr/share/doc/aptitude/

w32codecs unexist becaus ubuntu installed - x64.

Already install w64codecs but it doesn't help.

Why this error ocures again and again?

http://ubuntuforums.org/showthread.php?t=502179 here I find the same problem but mencoder show error when I try to use key

-xvidencopts

Try running update-manager, it should give you an update on mencoder since the medibuntu has it's own version of mencoder as well. Might be needed to use those w64codecs.

Sorry again but how I can update mencoder? I type "apt-get install mplayer" and it downloads near 53mb of something. Then I try command:

mencoder test.avi -o test_converted.avi -oac copy -ovc lavc -lavcopts vcodec=mpeg4:mbd=1:vbitrate=1800 -ffourcc XVID
