[x264-devel] X264 encoder crash run on android2.2 when optimization with neon

[chris.huang]

Dear All,
  
    I have encountered problems in my nexus one phone, I have seen some similar problem in google search, when I  encoder camera picture to h264 format with libx264 in armv7-a (enable -mcpu=cortex-a8 -mfpu=neon),  the application will crash,But the application run ok and I can see the picture if I disable-asm(disable -mcpu=cortex-a8 -mfpu=neon) feature. 
    I have debug the source code, and find it crash in common/arm/mc-c.c x264_memcpy_aligned_neon function , when i try to use common memcpy to replace it, it will not crash but display picture will have many garbage colors.
    Could anyone give me some suggetion? Thanks very much.
