x264 for uclinux on DE2

Altera_Forum · ‎07-31-2006

Hi,

I want to add x264( encoder for h.264) to uclinux as an application.

I follow uClinux-dist-test/Documentation/Adding-User-Apps-HOWTO .

1. add a line to user/Makefile , dir_$(CONFIG_USER_X264_X264) +=x264

2. add a line to misc section of config/config.in, bool 'x264' CONFIG_USER_X264_X264

3. mkdir ~/uClinux-dist-test/user/x264

4. put all the code in user/x264 dir,

5. create Makefile in user/hello dir,

The Makefile ad follows:

# Makefile

include config.mak

CC=gcc

LDFLAGS= -lm -s

AS=nasm

ASFLAGS=-f elf

VFW=no

EXE=

VIS=no

HAVE_GETOPT_LONG=1

DEVNULL=/dev/null

CONFIGURE_ARGS=

I have "make" and "make linux image", but in the uClinux-test-dist/romfs/bin the executable file is elf, not flat. So when I download the kennal to the board ,the application did not work. I had tried to modify

"LDFLAGE= -W1 -elf2flt -lm -s" ,it was not useful.

Pls give me some advice.

Thanks!

Hi,

There is nobody to do the work about h.264 for uclinux on DE2???

If someone got some experience,pls give me some advice.Thanks!
