  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

cd ffmpeg
    
./configure $FFMPEG_FLAGS --extra-cflags="$CFLAGS $EXTRA_CFLAGS" --extra-ldflags="$EXTRA_LDFLAGS"

    the error :

    ERROR: opus not found
    

    
If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "config.log" produced by configure as this will help solving the problem.

    if want i can post the config.log content, but it is big.

    on folder ffmpeg I have a git clone from source.ffmpeg.org on branch release/1.2

  • Using FFMPEG library in PPAPI : Naclports with FFmpeg

    30 avril 2017, par rasulzhan

    I have configured Webports, ffmpeg ; and I have created the following Makefile for the current project. However, I have met some problem with ffmpeg library linking.

    $ TOOLCHAIN=pnacl make
    
  LINK pnacl/Release/client_unstripped.bc
    
pnacl/Release/src/client.o: error: undefined reference to 'av_register_all'
    
make: *** [pnacl/Release/client_unstripped.bc] Error 1

    Can you tell me what I am doing wrong here, my Makefile is shown below :

    VALID_TOOLCHAINS := pnacl glibc clang-newlib win

    NACL_SDK_ROOT ?= $(abspath $(CURDIR)/../..)

    TARGET = client

    OTHERDIR=src

    INC_DIR = inc

    FFMPEG_INC_DIR = ../../toolchain/mac_pnacl/le32-nacl/usr/include

    INCLUDES = -I$(INC_DIR) -I$(FFMPEG_INC_DIR)

    include $(NACL_SDK_ROOT)/tools/common.mk

    CHROME_ARGS += —allow-nacl-socket-api=localhost

    LIBS = nacl_io ppapi_cpp ppapi

    # Build rules generated by macros from common.mk :

    $(foreach src,$(SOURCES),$(eval $(call
    COMPILE_RULE,$(src),$(CFLAGS))))

    # The PNaCl workflow uses both an unstripped and finalized/stripped binary.
    # On NaCl, only produce a stripped binary for Release configs (not Debug). ifneq (,$(or $(findstring pnacl,$(TOOLCHAIN)),$(findstring

    LINK_RULE,$(TARGET),$(SOURCES),$(LIBS),$(DEPS))) endif

    $(eval $(call NMF_RULE,$(TARGET),))

    And here is the way, how the library has been used in the class context.

    class VideoDecodePack {
