[issa82]

Hi,
Im trying to cross compile vlc from source code (vlc-2.1.4) to run as command line on android 4.2 (arm7).

toolchain already in place, FFMPEG installed successfully

after few trial below is the configuration:

Code: Select all

export CC=/home/toolchain/bin/arm-linux-androideabi-gcc export CXX=/home/toolchain/bin/arm-linux-androideabi-g++ ./configure '--disable-v4l' '--disable-v4l2' '--disable-nls' '--disable-mozilla' '--disable-dbus' '--disable-dbus-control' '--disable-telepathy' '--disable-lua' '--disable-cdda' '--disable-vcd' '--disable-dvb' '-disable-libcddb' '-disable-x11' '--disable-glx' '--disable-opengl' '--disable-xvideo' '--disable-xvmc' '--disable-freetype' '--disable-fontconfig' '--disable-fb' '--disable-qt4' '--disable-skins2' '--disable-sdl' '--disable-sdl-image' '--disable-notify' '--disable-libgcrypt' '--disable-mad' '--enable-avcodec' '--enable-avformat' '--disable-swscale' '--disable-postproc' '--disable-a52' '--disable-remoteosd' '--disable-live555' --host=arm-linux --without-x --disable-xcb --without-kde-solid --disable-dvdnav --disable-dvdread --disable-vcd --disable-libcddb --disable-qt --with-arch=arm-linux CPPFLAGS=-I/home/toolchain/sysroot/usr/include LDFLAGS=-L/home/toolchain/sysroot/usr/lib --disable-alsa --disable-theora --disable-x264 --disable-ogg --disable-mux_ogg --disable-libxml2 --disable-bonjour --disable-udev --disable-mtp --disable-upnp --disable-atmo --prefix=/home/toolchain/sysroot/usr --without-x --program-prefix=arm7 --with-contrib=/home/toolchain/sysroot/usr/ --prefix=/home/toolchain/sysroot/usr/local/

when i compile i get:

Code: Select all

VLC for Android cannot run from the command line, sorry.

[issa82]

Thanks for the reply, why not?
just to clarify, im not building vlc as APK file for android, im cross compiling it to run as command line on linux-arm, android platform

[flx42]

Why are you trying to do that? Which feature of VLC do you want to use that requires running it from command line on Android?

[edwardw]

You cannot run the Android port from the command line, because it is written in Java and using the Android Runtime.

I got it working, thanks for the replies

Im compiling VLC from default source code and not from android version

[issa82]

Why are you trying to do that? Which feature of VLC do you want to use that requires running it from command line on Android?

Android VLC (LIBVLC) does not have deinterlace feature.

This is not supported and will not work.

[issa82]

This is not supported and will not work.

I got vlc working on command line on android platform ARM7, do you want the binary to test it your self?

[edwardw]

It is probably broken in that it cannot access various Android system APIs, which depend on the Android Runtime, like video output for instance.

It is probably broken in that it cannot access various Android system APIs, which depend on the Android Runtime, like video output for instance.

It doesnt need to access android system API, I am using it to as streaming system on linux command line, it receive the stream from network do what ever its requested to do, and then stream it back on local system where android native media player will read the stream from unicast or http url and play it as normal.

PS: this not for mobiles or tablets its for special android based STB.

Thanks for the reply anyways

I have used the vlc-nox build in Debian in a chroot on Android. I built the chroot using the Lil Debi app. It works, but is old. The deb-multimedia repos have nice fresh builds though, if you add them.
