Streaming and transcoding

Postby Lisofc » 02 Apr 2008 11:25

Hi,

After search on google and into this forum, I don't understand why my commande line doesn't work. (the input stream bitrate is 128k and the command line was in the wiki)

Code: Select all

./vlc -I dummy -vvv --color http://scfire-dll-aa01.stream.aol.com:80/stream/1048 --sout "#transcode{aenc=mp3,ab=64}:std{access=shout{mp3,name='TT',url=''},mux=raw,dst=source:pass@ip:port}" vlc:quit
I can stream the input file but there is no transcoding, the output stream is 128k also...
And the vlc stop to send packets after 15 secondes...

I can see there is a problem with the "codec mp3"... I have compiled ffmpeg with libmp3lame....
And VLC with : $ ./configure --enable-ffmpeg --with-ffmpeg-mp3lame --enable-mad --disable-libdvbpsi --disable-a52 --disable-dca --enable-libmpeg2 --disable-fribidi --disable-speex --disable-flac --enable-live555 --disable-caca -disable-kde --disable-qt --enable-release --enable-x264 --disable-flashsv --disable-wxwidgets --disable-skins2 --disable-v4l --disable-dvb --enable-shout --disable-glx


Can you see a problem in the command line maybe ?

Thanks.

Here the logs :

Thanks.

Ok, the problem ffmpeg encoder error: cannot find encoder MPEG Audio layer 1/2/3 is gone.

But the stream is online only 15 secondes, and there is no transcoding... and after 15 secondes, there is no source again connected to my server...

Another idea ?

you compiled with disable-a52 so you should try recompile with enable-a52 ;)

Ok. I haven't got libmad...

Code: Select all

apt-get install libmad0 libmad0-dev then ./configure --enable-ffmpeg --with-ffmpeg-mp3lame --enable-mad --disable-libdvbpsi --enable-a52 --disable-dca --enable-libmpeg2 --disable-fribidi --disable-speex --disable-flac --enable-live555 --disable-caca -disable-kde --disable-qt --enable-release --enable-x264 --disable-flashsv --disable-wxwidgets --disable-skins2 --disable-v4l --disable-dvb --enable-shout --disable-glx
And then a "make".

But I have this problem now :

Code: Select all

[00000569] mpgatofixed32 private debug: libmad error: bad main_data_begin pointer [00000569] mpgatofixed32 private debug: libmad error: bad main_data_begin pointer
Any idea ?

Thanks.

You have to install it on your system first. Make a check if it is installed.
