  fate : Remove vsync drop from some h264 tests
  Note some tests need vsync drop to produce exact timestamps, these seem not to
  
  need it. quite likely many more dont need it either, ive not checked beyond finding
  
  one that needs it and the ones which have it removed

• lavc : introduce a new decoding/encoding API with decoupled input/output

  22 mars 2016, par wm4

  lavc : introduce a new decoding/encoding API with decoupled input/output
  Until now, the decoding API was restricted to outputting 0 or 1 frames
  
  per input packet. It also enforces a somewhat rigid dataflow in general.
  This new API seeks to relax these restrictions by decoupling input and
  
  output. Instead of doing a single call on each decode step, which may
  
  consume the packet and may produce output, the new API requires the user
  
  to send input first, and then ask for output.
  For now, there are no codecs supporting this API. The API can work with
  
  codecs using the old API, and most code added here is to make them
  
  interoperate. The reverse is not possible, although for audio it might.

• 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

  CFLAGS = -Wall -g -O2 $(INCLUDES)
  -L../../toolchain/mac_pnacl/le32-nacl/usr/lib -lavformat \
  -lvpx -lvorbisenc -lvorbis -logg -ltheoraenc -ltheoradec -logg -lmp3lame -lm -pthread -lavcodec -lvpx -lvorbisenc -lvorbis -logg \
  -ltheoraenc -ltheoradec -logg -lmp3lame -lm -pthread -lswresample -lm -lavutil -lm -lavdevice -lavfilter

  SOURCES = $(OTHERDIR)/tcp_util.cc $(OTHERDIR)/tpool.cc
  $(OTHERDIR)/net.cc $(OTHERDIR)/rtsp_response.cc \ $(OTHERDIR)/rtsp.cc
  $(OTHERDIR)/rtsp_common.cc \ $(OTHERDIR)/rtsp_client.cc
  $(OTHERDIR)/udp_util.cc \ $(OTHERDIR)/client.cc

  # 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)),$(findstring
  Release,$(CONFIG)))) $(eval $(call
  LINK_RULE,$(TARGET)_unstripped,$(SOURCES),$(LIBS),$(DEPS))) $(eval
  $(call STRIP_RULE,$(TARGET),$(TARGET)_unstripped)) else $(eval $(call
  LINK_RULE,$(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 {
  
  public:
  
      VideoDecodePack() {
  
          av_register_all();
  
      }
  
  };
  
  
  
  class ClientInstance : public pp::Instance {
  
   public:
  
    explicit ClientInstance(PP_Instance instance) : pp::Instance(instance){
  
      cses = InitRtspClientSession();
  
      _videoDecoder = new VideoDecodePack();
  
    }
