Compiling ffmpeg for android

[Luis Linietsky]

Hello there,
I have been trying unsuccessfully to build Tutorial5 from the gstreamer android tutorials with ffmpeg plugin.

I keep getting the following error:

luigi at Fender:~/workspace/Tutorial5$ ndk-build
GStreamer      : [GEN] => gst-build/gstreamer_android.c
GStreamer      : [COMPILE] => gst-build/gstreamer_android.c
GStreamer      : [LINK] => gst-build/libgstreamer_android.so
/home/luigi/projects/android-ndk-r8d/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld.gold: /home/luigi/projects/gstreamer-sdk/lib/libavcodec.a(flashsvenc.o): in function flashsv_encode_frame:libavcodec/flashsvenc.c:169: error: undefined reference to 'compress2'
/home/luigi/projects/android-ndk-r8d/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld.gold: /home/luigi/projects/gstreamer-sdk/lib/libavcodec.a(tiffenc.o): in function encode_strip:libavcodec/tiffenc.c:165: error: undefined reference to 'compress'

The .o files are referencing compress and compress2 from zlib, but the symbols in such library are z_compress and z_compress2 (there is a #define compress z_compress in the header), so i guess this is a compilation error? also I just need to use h264 from ffmpeg, so is there any plugin or module i can disable for this error to not happen? (I don't really need flash or tiff decoding)
