• 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" ?

• Ffmpeg won't copy excerpt of video correctly

  5 mai 2022, par JR Jr.

  I am using a DOS batch to automate and copy excerpts of various high definition videos (mkv's with more than 1GB each).
The script is very convenient and runs fast and fine, but Ffmpeg is not doing its job correctly (it seems Murphy's law is inexorably enthralled into technology, things never come easy, which is why I love and hate it).

  


  Anyway, to cut a long story short, each time the batch job runs, a code like below is executed (pardon me the indiscrete folder name, it's about the 90's TV show, it's not porn !).

  


  call "C:\ffmpeg\bin\ffmpeg.exe" -y -i "D:\100\Sexo\S01\SATC - S01E03 - Bay of Married Pigs.mkv" -ss 00:18:05 -to 00:19:15 -codec copy "002-SATC - S01E03 - Bay of Married Pigs-00_18_05-00_19_15.mp4"


  


  The problem is that the first 6 seconds or so of the resulting video has no video, only audio with a frozen image that only starts to move after about 6 seconds, which is a huge defect, not to mention very annoying (a big let down, after all my meticulous scripting work :(). And this happens for most of the files, except a few ones.

  


  Even though this is copying and changing the format from mkv to mp4, per another thread on this site (https://askubuntu.com/questions/396883/how-to-simply-convert-video-files-i-e-mkv-to-mp4), this is not re-encoding, so this is not the issue. Actually, the same problem occurs even if I don't change the format from mkv to mp4.

  


  Even though I foresee a "there's no way to fix this", let me ask : is there a way to fix this ? Hopefully there is a way.

  


• Anomalie #3430 (Nouveau) : les champs multi ne fonctionnent plus si une des rubriques n’est plus e...

  18 avril 2015

  Le bug est un peu compliqué

  Voici la configuration :
  - Site multilingue Francais / Anglais
  - Réglages : Traduction Rubrique : non - Traduction Article : oui
  - Pas de forcer_lang

  Si on a les rubriques suivantes
  - 10. Actu
  - 20. Gouache
  - 30 Musique

  Lorsqu’on liste les rubriques dans l’espace public avec un ?lang=en
  on obtient
  - News
  - Gouache
  - Musique

  Le fait d’avoir une rubrique sans multi (gouache) casse le fonctionnement des multi à venir.
  même en forcant avec un [(#TITRE|extraire_multi{#ENV{lang})] impossible d’avoir le multi sur music
  actuellement, la seule façon de resoudre le pb est de placer multi sur toutes les rubriques même si c’est inutile
