Cannot find encoder MPEG-2 Video

[mapiazza]

HI all,
I'm newbe of VLC, I'm testing the trasncoder capabilities of VLC and I have a issue, when I try to trascode from a mp4 file to a mpeg2 stream I have this error:

avcodec encoder error: cannot find encoder MPEG-2 Video
[00000415] stream_out_transcode stream out error: cannot find video encoder (module:any fourcc:mp2v)

Probably I'm doing some error on the commad line or I missing some library.

The sever is a Ubuntu 8.10 server edition and the VLC is 0.9.4

Any clue?
Thanks
Matteo

HI

After the installation of ubuntu-restricted-extras packet I'm able to use mp1v as encoder but not mp2v:

I have this error:

Ubuntu removed encoders from VLC.

Is there any way to add them back in again? I do not want to install "ubuntu-restricted-extras" since it'll fubar some of my other stuff. Which libs should I install to get MPEG2 encoding back?

[Brownstone]

Nevermind, I found them:

Code: Select all

sudo apt-get install ffmpeg libavcodec-unstripped-51

Yes, this is the good way.
