vlc cross-compiles for ARM but cannot stream MP3

[kcleung]

I have successfully cross-compiled VLC for ARM on AMD64 host. I am hoping to get a very simple VLC with only the ability to stream MP3 using HTTP. No GUI is available or desired, and if possible to remove even the command-line interface.

The options passed to configure are:

Code: Select all

--target=arm-linux \ --host=arm-linux \ --build=x86_64-pc-linux-gnu \ --prefix=/usr \ --exec-prefix=/usr \ --sysconfdir=/etc \ --without-html-dir --disable-gtk-doc \ --disable-nls \ \ --disable-dbus --disable-avcodec --disable-avformat --disable-swscale --disable-postproc --disable-a52 --disable-fribidi --disable-skins2 --disable-remoteosd --disable-vlm --enable-static --disable-shared --disable-glx --enable-run-as-root --disable-dependency-tracking --disable-rpath --enable-release --enable-optimize-memory --with-libiconv-prefix=/home/user/buildroot/build_arm/staging_dir/usr --enable-mad --disable-theora --disable-vorbis --disable-tremor --disable-ogg

However, the compiled VLC refuses to stream MP3 files.

Code: Select all

Is there any additional environment variables or options to pass to configure, for VLC to work?

Thanks in advance.

Let's try something else, can you do a vlc --list ?

[kcleung]

here's the output of "vlc --list":

Code: Select all

# vlc --list VLC media player 1.0.1 Goldeneye main main program

Now this is weird!

I tried to enable the ncurses interface. configure finds the ncurses library:

Code: Select all

checking ncurses.h usability... yes checking ncurses.h presence... yes checking for ncurses.h... yes checking for mvprintw in -lncursesw... no checking for mvprintw in -lncurses... yes checking for tgetent in -lncurses... yes

The ncurses module is compiled:

Yeah, please delete you vlc cache and preferences.

This is what I've got after running "rm -rf /root/.cache /root/.config" (only one user in the ARM target environment):

This is wrong

Try to use --plugin-path to tell vlc where are the modules you compiled

[kcleung]

Thank God I got this working with 0.9.9a before and can compare the installations.

Somehow, the 1.0.1 make install is not copying the plugin files where they should, while 0.9.9a does it correctly. I'm investigating.

Could my mistake be due to me enabling the --disabled-shared option for version 1.0.1? I turned it on, to workaround a problem where libvlccore / libvlc are built in wrong order. But it seems no plugins are being generated due to this option too.

[Rémi Denis-Courmont]

Only libvlc can be built statically. libvlccore and plugins must be shared.
