• avplay : drop support for building without lavfi

  avplay : drop support for building without lavfi
  lavfi has been considered to be stable for a while now, so it is enabled
  
  in most configurations. Supporting avplay without lavfi requires a lot
  
  of nontrivial ifdef mess for no good reason.

• Error while building PJSIP with FFMPEG storage size of 'dstFormat' isn't known

  8 mai 2018, par Dmitry Zhgun

  Building PJSIP for armeabi with FFMPEG gives me following output :

  ../src/pjmedia/converter_libswscale.c: In function 'factory_create_converter':
  
  ../src/pjmedia/converter_libswscale.c:70:24: error: storage size of 'srcFormat' isn't known
  
   enum AVPixelFormat srcFormat, dstFormat;
  
                      ^

  I’ve read many articles about problems with PixelFormat -> AVPixelFormat in newer versions of FFMPEG(Such as one i’ve built for PJSIP) - I got all of my pj sources updated according with AVPixelFormat.

  Building environment :

  Ubuntu 16.04 LTS 64bit running in VirtualBox

  PJSIP 2.6

  FFMPEG 3.0.9

  Compiling PJSIP with flags :

  #define PJMEDIA_HAS_VIDEO 1

  #define PJMEDIA_HAS_FFMPEG 1

  NDK-flag :

  —with-ffmpeg="$BASE_DIR/ffmpeg-output"

  ffmpeg-output folder contains these files :

  • libavcodec.so
  • libavcodec.so.57
  • libavcodec.so.57.24.102
  • libavdevice.so
  • libavdevice.so.57
  • libavdevice.so.57.0.101
  • libavfilter.so
  • libavfilter.so.6
  • libavfilter.so.6.31.100
  • libavformat.so
  • libavformat.so.57
  • libavformat.so.57.25.100
  • libavutil.so
  • libavutil.so.55
  • libavutil.so.55.17.103
  • libpostproc.so
  • libpostproc.so.54
  • libpostproc.so.54.0.100
  • libswresample.so
  • libswresample.so.2
  • libswresample.so.2.0.101
  • libswscale.so
  • libswscale.so.4
  • libswscale.so.4.0.100

  Trying to build different versions of FFMPEG didn’t work at all(Got the same error at the end)

  Any help will be appreciated.

  UPD :
  Is there any strange stuff aboud AVPixelFormat in this part of compiler output related to ffmpeg :

  checking ffmpeg packages...  libavdevice libavformat libavcodec libswscale libavutil
  
  checking for enum AVPixelFormat... no
  
  checking for v4l2_open in -lv4l2... no
  
  Checking if OpenH264 is disabled... yes
  
  Skipping Intel IPP settings (not wanted)

  I mean the line says "checking for enum AVPixelFormat... no" - is there any flag I need to write to say to PJSIP "you have to work with AVPixelFormat" ?
