• ERROR : opus not found using pkg-config in msys64 on Windows

  10 août 2022, par prostargamer

  I'm trying to build ffmpeg.

  


  I downloaded msys2 x64 from the official website. This is the latest version.
  
Executed "pacman-Syu", rebooted msys and executed "pacman-Su".

  


  In your file build_ffmpeg_win.sh ffmpeg installs the following packages using pacman :
  

  


  pacman --noconfirm -Sy
pacman --noconfirm -S msys/make
pacman --noconfirm -S mingw64/mingw-w64-x86_64-opus
pacman --noconfirm -S pkg-config
pacman --noconfirm -S diffutils
pacman --noconfirm -S mingw-w64-x86_64-pkg-config


  


  Then I run "pacman -Qet" in order to get the list of packages :

  


  $ pacman -Qet
base 2020.12-1
diffutils 3.8-1
make 4.3-1
mingw-w64-x86_64-opus 1.3.1-4
pkg-config 0.29.2-4


  


  The opus package is installed.

  


  However, when I try to run "build_ffmpeg_win.sh", then I get the following error at the stage ./configure : "ERROR : opus not found using pkg-config"

  


  The following folders and files are located in the "msys64\mingw64\lib" folder :

  


  pkgconfig (folder)
libopus.a
libopus.dll.a


  


  There is an opus.pc file in the msys64\mingw64\lib\pkgconfig folder, the contents of which refer to /mingw64/lib and /mingw64/include.
pkg-config knows about opus, but for some reason this error occurs during ./configure.

  


  How can I solve this problem ?

  


• How to make icecast relay the metadata of mp3 stream from ffmpeg ?

  8 janvier 2021, par Anonymous Mouse

  I'm trying to relay a internet radio stream with the command :

  


  ffmpeg -re -i 'http://internetradiourl'-vn -acodec copy -f tee -map 0:a "[f=mp3]icecast://source:pass@icecast:8000/a|[f=mp3]icecast://source:pass@icecast:8000/b"


  


  the output stream has all the metadata :

  


  Output #0, tee, to '[f=mp3]icecast://source:pass@icecast:8000/a|[f=mp3]icecast://source:pass@icecast:8000/b':
  Metadata:
    audiocodec      : MP3
    audiodevice     : IN  1+2 (Digigram LoLa280)

    cue_time_duration: 44.365
    cue_time_start  : 1610035039552
    cue_title       : PSA - Danny - Parking (Jun 2020)
    encoder         : Lavf58.45.100
    Stream #0:0: Audio: mp3, 44100 Hz, stereo, fltp, 98304 kb/s
Stream mapping:
  Stream #0:1 -> #0:0 (copy)


  


  but if a client connects to the icecast server, the metadata is lost :
ffprobe https://icecasturl/a

  


  Input #0, mp3, from 'https://icecasturl/a':
  Metadata:
    icy-pub         : 0
    icy-metadata    : 1
    StreamTitle     :
  Duration: N/A, start: 0.000000, bitrate: 96 kb/s
    Stream #0:0: Audio: mp3, 44100 Hz, stereo, fltp, 96 kb/s


  


  How can I configure icecast so that it forwards all the metadata of the source stream ?
