HI3516A ffmpeg x264 Cross Compilation

Environment: Centos_6.5_x86

Cross tool chain: arm-hisiv300-linux-

Steps:

1. Download x264:

# git clone git://git.videolan.org/x264.git

2. Download FFmpeg

git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg

3. Cross-compiling

1) [Root@demo x264]#./configure--enable-pthread--enable-static--disable-shared--host=arm-linux--disable-asm

2) Modify Config.mak

[Root@demo FFmpeg] #make
Summary of issues:

1) ffmpeg undefined reference to symbol ' Dlclose '

Configure option, add--EXTRA-LIBS=-LDL to it.

2) Report an error:

X264.c:50:34:error:libavformat/avformat.h:no such file or directory
X264.c:51:30:error:libavutil/pixfmt.h:no such file or directory

Modify the tenth line of the Config.mak file and add-i//home/ffmpeg/ffmpeg/ffmpeg to find it.

3) After running the Make command, the compilation passes, but there is an error linking. When compiling the LIBX264.A library, the command shown is:

Arm-linux-arlibx264.a ....

The make file has no spaces between the link command and the library name, causing the system to not recognize this command

Manually execute the following command:

Arm-hisiv300-linux-ar RC libx264.a common/mc.o common/predict.o COMMON/PIXEL.O common/macroblock.o COMMON/FRAME.O COMMON/DCT.O common/cpu.o common/cabac.o common/common.o common/osdep.o common/rectangle.o common/set.o common/ QUANT.O common/deblock.o common/vlc.o common/mvpred.o common/bitstream.o encoder/analyse.o encoder/me.o encoder/ RATECONTROL.O encoder/set.o encoder/macroblock.o encoder/cabac.o encoder/cavlc.o encoder/encoder.o encoder/ LOOKAHEAD.O COMMON/THREADPOOL.O

4) Arm-linux-ranlib libx264.a (for generating x264-config.h files)
