[FFmpeg-user] AAC decoding on Android

[Ali Shaheen]

Hi,
    I tried with latest 0.11.1 ..it was giving error with avcodec_init() ..
i think now it has been removed in 0.11.1.
After commenting that, now i am getting SIGSEGV fault when
av_find_stream_info(formatctx)     tries to fill my formatctx with the info
from custom stream ( AVIOContext) .

I think i should move back to 0.8.11 again on which it was working :)

Thanks
