Got stuck when booting

[Kiki]

Hi all，
I was trying to port ffmpeg onto Android, but I got stuck when
booting with my "system.img".
I built libavutil, libavcodec and libavforbat first;
And I wrote a simple ffmpeg player (changed libmediaplayerservice);
Log and prelink map attaching.

Seems loading "libavformat.so" failed.
09-28 09:13:19.046: INFO/DalvikVM(593): Unable to dlopen(/system/lib/
libandroid_servers.so): Cannot load library: link_image[1638]: 553
could not load needed library 'libsystem_server.so' for
'libandroid_servers.so' (link_image[1638]: 553 could not load needed

prelinked library 'libavformat.so' mapped at 0x44b74000, not at
0x2f500000)))

How to fix it? (prelinked library 'libavformat.so' mapped at
0x44b74000, not at 0x2f500000)
I addressed libavformat at 0x2f500000 in prelink map.

Hi All,

Good news!I can boot the emulator now.
I add several logs to linker.c, and the output info surprised me.
All these 3 so size are bigger than built lib size more than 50%!
That is to say, "libavcodec.so" under /out/target/product/generic/
obj/
lib is 2M,
but you can see its real size is more than 6M when running!
I gave the libavcodec.so a slot in "prelink-linux-arm.map" with the
size of 3M only, so it got stuck when booting-_-//
When I changed the slot size to 7M, booting successfully!
I hope this case can help other people.


Nevertheless, who can tell me why the lib size became so large when
running?
