Compiling vlc for linux: cannot find encoder (ffmeg)

Postby DeftonesXP » 06 Jun 2005 17:16

Hi vlc team !

First of all, thanks for your great job !!

Here's my problem :
I am trying to use vlc under linux ( RedHat 8.0 ).
Since all the rpms that I could find are for RH 7 or 9, I decided to complile vlc. So I went to your source download page and downloaded all the files. I compiled everything.

Then, I tried to transcode a mpeg file to mp4 but I got this error :

[root /]# vlc
VLC media player 0.8.1 Janus
Remote control interface initialized, `h' for help
trying to add /record/try.mpg :sout=#transcode{vcodec=mp4v,vb=128,scale=0.25,acodec=mp4a,ab=64}:duplicate{dst=std{access=file,mux=mp4,url=/record/test.mp4}} to playlist
add: returned 0 (no error)

[00000393] stream_out_transcode private error: cannot create video chain
[00000422] main packetizer error: cannot create packetizer output


So I thought that ffmpeg wasn't properly linked to vlc. I looked around and found that I forgot to include configure option with vlc. I included the codecs in the config. params (i.e. --enable-faac). Recompiled everything again ... didn't work :(

Then I found that I could do the same but with ffmpeg, and use --with-ffmpeg-faac in the vlc config. Another config to do!! just to be sure, I did a big 'make clean'... in case that would help me...

No... not at all ... I still get the same ffmpeg error !!! :evil:
Can someone help me please ?

Thanks !


Notes :
1) I know this command is working because I tested it using a windows version of VLC. I used the same mpg file in both tests.
2) I don't have any xWindows in linux, so I compiled vlc without xwin support.
3) Here's the configure options I am using for vlc and ffmpeg :
ffmpeg :
./configure --prefix=$INST --enable-pp --enable-gpl --enable-libogg --enable-vorbis --enable-faad --enable-faac --enable-a52 --enable-mp3lame --enable-shared
vlc :
./configure --prefix=$INST \

Ok , since no one can answer my question, here's an easier one!

Since I compiled and installed vlc many times, I searched for old libs lying around. And guess what...

[root]# find / -name libfb_plugin.so
/lib/vlc/video_output/libfb_plugin.so
/usr/lib/vlc/video_output/libfb_plugin.so
/usr/local/lib/vlc/video_output/libfb_plugin.so
/usr/src/vlc/vlc-0.8.1/modules/video_output/libfb_plugin.so
[root]#

Ah AH!!! :oops:

If I was using this option when configuring vlc : --prefix=/usr/local
where should the libs be after doing a "make install" ?
Are the libs in /usr/local the only good ones ? If so, I will delete all the other dirs, like /usr/lib/vlc ... except the src dir :)

Thanks !

/me doesn't understand why ppl think that having the same error message indicates the same problem....


If 2 people drown, do you automatically assume that both drowned in the same way???
Don't use PMs for support questions.

-> I want to answer "Maybe it's because we are lot of newbies, and for undestand a problem, in first, I look if anybody else is in the same situation..."

Maybe our 2 problems are different, and I'm really interesting to know why...
