The VideoLAN Forums

I'm writing an android app which needs a media player (over rtsp) and after a lot of research I found that the best way to this is to compile the VLC app and start from there.
I've been trying to compile VLC on android. I followed "wiki.videolan.org/AndroidCompile" but didn't succeed.
Here is what I've done:

I'm using Kubuntu 12.10 and Eclipse juno (maybe irrelevant at this point)
All the packages mentioned in the AndroidCompile page are installed.
I don't see any error messages.
I uploaded the output of compile.sh here:
https://www.dropbox.com/s/s2867xttwu2o3 ... output.txt

The AndroidCompile page says that by now I should have an autogenerated debug apk in the bin/ folder. There is no bin/ folder in ~/workspace/android/ and there is no *.apk file *anywhere*. I thought if it has compiled correctly at least there should be some *.so files:
one more thing, in ~/workspace/android/ there is a script named gen-env.sh that supposedly generates a file named env.txt into vlc-android/assets/ and this script gets called by the make file. But there is no env.txt and in the output of compile.sh there is no mention of gen-env.sh

Anyway, I imported the vlc-android project into eclipse. Running it on its own of course doesn't work first I get an exception which can be fixed if I manually run gen-env.sh but then I get an error saying it couldn't load libvlcjni

So I tried to compile the native code.
I checked the Android.mk file and turns out VLC_SRC_DIR is not set. So:
I don't know what to do next. Am I doing something wrong? because these things haven't been mentioned in AndroidCompile. It just says run "sh compile.sh", import project into eclipse then run & enjoy!

I'd appreciate any help... I've been spending hours trying to get this to work.
Thanks

Install the 'yasm' package and run 'sh compile.sh' again. Also, I've updated AndroidCompile with this information.

Thank you for the quick response Edward. It compiled correctly (maybe?) but now it crashes as soon as I start the VLC app
Here is what I got from LogCat: I get this message whether I use x86 or armeabi (with NO_ARMV6 for emulator). I'm using android SDK 4.2 (API 17).
If it helps: Just a little suggestion, since the compile.sh doesn't produce any error messages if something fails due to a program missing (e.g. yasm) you might want to mention in the AndroidCompile that at the end we should get the "BUILD SUCCESSFUL" message.

EDIT: I'm using Eclipse Juno and ADT 21

In case anyone is interested, I solved the problem a few days ago...
Actually this is kinda embarrassing... in Eclipse instead of Import existing android project, I selected Import existing project.

Hi, I have explained my problem in other post. But I have read this post and my problem is like that shanab_sh says.
I execute 'sh compile.sh' and I get a message that says: BUILD SUCCESSFUL

But my problem is that I don't know how can I compile JNI source code in Eclipse Juno, when I modify a class of the JNI folder.
I have created a 'New Builder' following these guidelines: http://mobilepearls.com/labs/ndk-builder-in-eclipse\, but I get the following message in my console:
/home/vmg/workspace/android/android-ndk-r8c/build/core/add-application.mk:128: Android NDK: WARNING: APP_PLATFORM android-9 is larger than android:minSdkVersion 7 in ./AndroidManifest.xml

make: *** No rule to make target `jni/..//modules/codec/omxil/iomx.cpp', needed by `obj/local/armeabi/objs-debug/iomx-gingerbread/__//modules/codec/omxil/iomx.o'. Stop.

Also, when I run the application VLC for Android in the LogCat output I get this lines:

Please, help!

Don't use the Eclipse builder. You have to use follow the AndroidCompile page as linked above.

Thanks for the reply.

I have followed the guidelines of that page (http://wiki.videolan.org/AndroidCompile) and have got a project in Eclipse with the source code. When I run this project, it installs on the device correctly.
But my problem is that I want to modify the classes .c of the JNI folder and run this project and that the changes performe correctly. I have changed some things and when I run the application, it hasn't got those changes.

I want to know how can I compile the project in Eclipse and that the changes of these class, that are written in C language, take effect.

THanks!

This has nothing to do with Eclipse.

Thanks, again!
I have to compile the classes .c, for these changes take effect. I try to compile the class libvlcjni.c from the terminal and this is what I get:

vmg@bakio:~/workspace/android/android/vlc-android/jni$ ls
Android.mk eventfd.c pthread-condattr.c utils.h
aout.c libvlcjni.c pthread-once.c wchar

vmg@bakio:~/workspace/android/android/vlc-android/jni$ gcc libvlcjni.c
libvlcjni.c:29:21: fatal error: vlc/vlc.h: No such file or directory
compilation terminated.

Change directory back to the root of VLC for Android (~/workspace/android/android/), and try this:

Thanks for the reply!

I have modified the libvlcjni.c class with the following change:
#define LOG_TAG "VLC/JNI/Vir/main" instead of #define LOG_TAG "VLC/JNI/main" to see if the trace output has the new LOG_TAG.

And I have tried it:
source ./env.sh
make distclean -e
make -e

This is the message of output in the terminal:
But when I installed the application in my device, this is the message in the Log-cat output of Eclipse:

Thus, the applicacion doesn't run correctly.

THanks!

libvlcjni.c:29:21: fatal error: vlc/vlc.h: No such file or directory

Did not compile correctly.

Thanks! I haven't explained correctly.

I tried to compile libvlcjni.c and I got this: And edward answered me:

Change directory back to the root of VLC for Android (~/workspace/android/android/), and try this:

Code: Select all
source ./env.sh
make distclean -e
make -e

I tried it and the output of the terminal is as follows: I thought that the process was accomplished successfully and the libvlcjni.c class was compiled correctly, but when I installed the application in my device, this is the message in the Log-cat output of Eclipse:
I have seen that there are two errors:
Thus, the applicacion doesn't run correctly.

You do not compile like this ('gcc libvlcjni.c"), because it is trying to invoke host GCC for a cross compile, which makes no sense.

You must use Makefiles to build VLC for Android, as it is the only way that all the variables needed are set correctly.
