Hi all,

I can't seem to locate an librtmp.so v2.4 for Android anywhere (all the links are down) so I decided to compile my own, however it crashes XBMC and I can't figure out why.

Compilation Process:

1. Used 64bit Fedora Linux to compile
   
2. Got Android NDK from: http://developer.android.com/tools/sdk/ndk/index.html
   
3. Set up NDK with '/tmp/rtmpdump/android-ndk-r8e/build/tools/make-standalone-toolchain.sh platform=android-14 --install-dir=/tmp/rtmpdump/android-toolchain --system=linux-x86_64'
   
4. Set my path with 'export PATH="tmp/rtmpdump/android-toolchain/bin:$PATH"'
   
5. Got Polar SSL from: https://polarssl.org/download
   
6. Compiled Polar SSL with 'make CC=arm-linux-androideabi-gcc APPS='
   
7. Installed Polar SSL to android-toolchain with 'make install DESTDIR=/tmp/rtmpdump/android-toolchain/sysroot'
   
8. Got S74ck3r's version of rtmpdump from: https://github.com/S74ck3r/rtmpdump.git
   
9. Compiled with 'make SYS=android CROSS_COMPILE=arm-linux-androideabi- INC="-I/tmp/rtmpdump/android-toolchain/sysroot/include" CRYPTO=POLARSSL'
   

This gave me my librtmp.so.0 (librtmp.so symlink). I then copied this over to my tablet's XBMC lib folder but when starting XBMC it crashes when loading libCURL. Restoring librtmp.so fixes the issue.

Tail end of xbmc.log:

Any thoughts? Or anyone have a 2.4 binary I can try?

Thanks,

Hrm, as I read what I've typed, I wonder if libCURL is compiled with OpenSSL statically and when librtmp introduces PolarSSL they conflict. No idea how to do this with OpenSSL though..

Hrm, I get the exact same error with libcurl.so using those. I'm using Android 4.2.2 on a Nexus 10. Did you do anything specific other than copying the .so file over?

Thanks,

I got this same problem, http://forum.xbmc.org/showthread.php?tid=160248 yet oddly unlike yours mine got no replies.

Anyway, we did an "adb logcat" on the Nexus 7 4.2.2 and found it claims the reason you get a libcurl.so error is because when loading compiled librtmp's like you mentioned above, even though that method works on many other systems (obviously not using Android NDK), the Android claims "undefined symbol 'sqrt'"..... which means the Android is having issues with libm for some reason, thus refusing to load librtmp.so and then libcurl.so gets annoyed because it appearntly depends on librtmp.so.

I purposely tried putting -lm into my compile and still no go.

I dont have 4.2.2, only 4.1.
Probably the problem is related with different OS versions...

Thanks for your reply, seems we are getting closer and closer to the solution. At least we know now why I seen many ppl like other librtmp's yet we keep getting failure. Maybe if somebody finds the exact commands used to compile the offical librtmp.so in Android we can get somewhere .

Ok, I got a temporary fix for your solution. Use the librtmp.so file in Dropbox posted earlier in the thread.

https://www.dropbox.com/s/hbuqpw17snhw0tj/librtmp.so

Go to /data/data/org.xbmc.xbmc/lib
Replace the old librtmp with the new one.
Then change the permission to rwx r-x r-x or the same permission as all the other files in that folder
A simple permision chart:
(read write execute)
User (x x x )
Group (x _ x )
Other (x _ x )

Once you have done that, open XBMC and it will work. I used this with great success on Amazon plugin for Nexus 7, Nexus 10, and Galaxy S3 all running cyanogenmod rom. However, it won't work on Twitch TV, not sure why. Maybe some other bugs in that addon. Have not look it up yet.

WARNING: you have to redo this every time you reboot the device because Android will replace the new librtmp file with the old file from the XBMC apk file.

I am trying to repackage the XBMC.apk so it could install a new librtmp file instead of the old file but I am having problem with signature verification. I will post update once I got it working.

Hope this work for you.

A stupid question: I have replaced the file and it works, but when reboot my device the file is gone. Why is that?

[Laser78]

I wanted to tell you that I have already Seller LIBRTMP XBMC running on a computer in ANDROID (Minix X5)

A stupid question: I have replaced the file and it works, but when reboot my device the file is gone. Why is that?

Its because of apk signing on the Android. Muself and S74ck3r are producing a librtmp.so with all fixes and then I am going to place it in the libstagefright apk so that it remains on boot and I will host it on my Mediafire.

Should only be a few more days.

Thanks for fixing librtmp. Will this also solve the problem that the streams are out-of-synch? The video is too slow. Even in the low quality videos of ustvnow

AFAIK, my buddy has tested the file numerous times on his Nexus 7 and his videos have had no problems at all.

My USTVNow refuses to work on any of my XBMCs .

[RedPenguin]

I have created an Android APK with another signature meaning it will not install over-top the current XBMC you would have on your Android but should work where the file is not replaced over and over.

I just try and not installed.

I deleted the previous version of XBMC and tried to install this, but get the message "Application Not Installed".
