FFmpeg is software decoder.
libstagefright can support software (Google implement AVC, MPEG4, VP8, AAC, MP3, etc) and hardware decoder (some IC Vendors implement HW decoder core, TI, ST, etc.)

Sorry to bother you,
I have another question,if h264.c in libavcodec is just for software decode
and libstagefright is just for hardware decode?I'm now trying to use
stagefright in Android directly to do H/W decoder.
Thanks
