ffmpeg encoder error

[rptr]

I use Ubuntu Feisty Fawn 7.04. When I try to transcode an input stream in mp3 with vlc I obtain the following error message :

Code: Select all

[00000343] ffmpeg encoder debug: libavcodec initialized (interface 3345152 ) [00000343] ffmpeg encoder error: cannot find encoder MPEG Audio layer 1/2/3 [00000299] stream_out_transcode private error: cannot find encoder ((null))

For vlc installation I use the following command :

Code: Select all

sudo apt-get install vlc

I use this config for ffmpeg :

Code: Select all

FFmpeg version SVN-r9977, Copyright (c) 2000-2007 Fabrice Bellard, et al. configuration: --enable-gpl --enable-pp --enable-pthreads --enable-libogg --enable-libgsm --enable-dc1394 --disable-debug --enable-shared --prefix=/usr --enable-encoder=mp3 --enable-libmp3lame libavutil version: 49.4.1 libavcodec version: 51.40.4 libavformat version: 51.12.1 built on Aug 7 2007 15:02:48, gcc: 4.1.2 (Ubuntu 4.1.2-0ubuntu4)

I also try to install vlc manually with some modifications in the configuration...

Code: Select all

./configure --enable-ffmpeg --with-ffmpeg-tree=../ffmpeg --with-ffmpeg-mp3lame --with-ffmpeg-config-path=../ffmpeg/ffmpeg --enable-faad --enable-theora --enable-flac --enable-esd --enable-dvbpsi --enable-libmpeg2 --enable-vorbis --enable-sout --disable-mad --disable-libmpeg2 --disable-wxwidgets --disable-skins2

...but I obtain some errors while creating the makefile and then still the same error while transcoding in mp3. Do you have any suggestions ?

[funman]

did you install ffmpeg build over the ubuntu's ffmpeg ?

you can try ffmpeg builds of medibuntu or other sources, it should have the mp3 encoder

[rptr]

did you install ffmpeg build over the ubuntu's ffmpeg ?

Yes, exactly. ffmpeg is not the problem, I can easily encode in mp3 using this command :

Code: Select all

ffmpeg -i input -f mp3 output.mp3

My problem is that I want to do the mp3 conversion directly with vlc :

Code: Select all

vlc -vvv --color input --sout '#transcode{acodec=mp3,ab=128}:standard{access=udp,mux=ts,dst=230.1.1.1}'

[funman]

if there is errors during vlc compilation, it obviously won't work then :/

what if you use mux=raw ? (maybe streaming won't work, but just to check)

[rptr]

I know it Perhaps something is wrong in my config... Can you tell me if you see an error ?

what if you use mux=raw ? (maybe streaming won't work, but just to check)

Same error with mux=raw...

[Jean-Baptiste Kempf]

Did you clean your cache ?

[rptr]

Yes, but no effect... Still ffmpeg encoder error...

[Jean-Baptiste Kempf]

Have you try to not specify ffmpeg-config, but just ffmpeg-tree ?

[rptr]

Yes. As I said before, first I had the default vlc package installed using ubuntu synaptic package manager and then I try to reinstall manually over it. I obtain some "undefined references" while creating the makefile. I think this is the problem, but I don't understand why the "make" command generates these errors... Perhaps a wrong configuration ?

[funman]

paste the make output

[rptr]

end of make output...

[funman]

well you need to link to raw1394 libraries i guess.

either install the development files or use --disable-raw1394 in vlc (i'm not sure for the exact syntax)

[rptr]

I try --disable-raw1394 and also --disable-dc139... but always the same errors while executing make...

Perhaps can I send to you the vlc-config file ?

[funman]

well --disable-*1394 while building ffmpeg should do the trick

[rptr]

well --disable-*1394 while building ffmpeg should do the trick

I try that but always the same errors... Have you another solution ?

[funman]

no... works fine for me...

did you run

Code: Select all

sudo apt-get build-dep vlc

?

[rptr]

did you run

sudo apt-get build-dep vlc

?

Yes, already done.

[funman]

which version of vlc are you compiling ? you should try to compile the same than in ubuntu

even get the source package of vlc in ubuntu would be the best: apt-get source vlc

[rptr]

which version of vlc are you compiling ? you should try to compile the same than in ubuntu

vlc version is 0.8.6...

even get the source package of vlc in ubuntu would be the best: apt-get source vlc

there is no possibility to transcode in mp3 with the source package in ubuntu...

[funman]

use ffmpeg or lame

[rptr]

I already use ffmpeg : vlc to read | ffmpeg to encode in mp3 | vlc to stream

But it would be better with only vlc... if possible

[rptr]

I think the best thing to do is to uninstall vlc and to reinstall it. Can you give me a correct configuration to do that ? I just need the defaults options and ffmpeg, ffmpeg-mp3lame. Thanks

[funman]

??? option to build it or install it via apt-get ?

[rptr]

To build it...

[funman]

well the defaults go well too
