• Can build & make video call with pjsip and ffmpeg

  10 mai 2023, par QViet

  I try to build PJSIP with ffmpeg with this config :

  


  i Follow those step :

  


  

  • build need lib and place in thirdparty folder name ffmpeg

  


  • setup link lib & header already.

  


  • run build with "$configure —with-ffmpeg="

  


  • config_site.h add :

  


  


  


  #define PJMEDIA_HAS_OPENH264_CODEC 1 
#define PJMEDIA_HAS_VIDEO 1 
#define PJMEDIA_VIDEO_DEV_HAS_FFMPEG 1 
#define PJMEDIA_HAS_FFMPEG_VID_CODEC 1 
#define PJMEDIA_HAS_FFMPEG 1 
#define PJMEDIA_HAS_FFMPEG_CODEC_H264 1 
#define PJMEDIA_HAS_LIBAVDEVICE 1 
#define PJMEDIA_HAS_OPENH264_CODEC 1


  


  


  I see have to enable PJMEDIA_HAS_OPENH264_CODEC , if not, can build success but when import will receive this error :

  


  Undefined symbol: _WelsCreateDecoder


  


  cause miss wels package exits in openh264 lib.

  


  The build with success after all with above config but in this :

  


     pj_status_t status = pjsua_vid_enum_codecs(videoCodecInfo, &videoCodecCount);


  


  the codec info just show 1 codec is "H264/97" -> is OpenH264 codec, i can't see ffmpeg here.
When im start call like normal, see log openh264 init call/ open camera .

  


  What i need step to using ffmpeg, i can see any docs about it

  


  can you help me ?

  


  ** this i log call stack :**

  I have tried asking ChatGPT, Gemini, or Bing, and they always lead me into a loop of errors that cannot be resolved. This error only occurs when the song naturally finishes playing due to its duration. If the song is playing and I use the command !skip, the next song in the queue will play and function normally. I noticed that it seems like if a song ends naturally, the song queue is also cleared immediately. I hope someone can help me with this

  


• ffmpeg Sound going out of sync with -concat or -ss

  6 août 2012, par Jared Glass

  I have a tool that spits out video from a 3D application and then concats the individual videos to make a sequence. But the sound seems to go out of sync in the sequence (the inividual files are fine) and it stutters in VLC and Quicktime. Windows media player seems to handle it bes to my supprise, yet it still goes out of sync. I have two senarios, one works and one doesn't but i need both working :

  Working :
  get already created out movs...

  convert to avi :
  os.system( ffmpeg + " -i C:\clip.mov -sameq -r 24 -y C:\clip.avi")

  concat to avi sequence :
  os.system( ffmpeg + ''' -i concat: C:\clip.avi|C:\clip1.avi|C:\clip2.avi -sameq -r 24 -y C:\sequence.avi''' )

  convert sequence to mov :
  os.system( ffmpeg + " -i C:\sequence.avi -sameq -r 24 -y C:\sequence.mov")

  Not Working :
  create individual avi's from 3D program...

  cut down to correct length :
  os.system(ffmpeg + " -i C:\clip.avi -sameq -r 24 -ss " + startTime + " -vframes " + totalFrames + " -y C:\clip.avi" )

  concat to avi sequence :
  os.system( ffmpeg + ''' -i concat: C:\clip.avi|C:\clip1.avi|C:\clip2.avi -sameq -r 24 -y C:\sequence.avi''' )

  convert sequence to mov :
  os.system( ffmpeg + " -i C:\sequence.avi -sameq -r 24 -y C:\sequence.mov")

  convert individual avi's to mov :
  os.system( ffmpeg + " -i C:\clip.avi-sameq -r 24 -y C:\clip.mov")

  Please let me know where I've gone wrong ?
