  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • {OpenAL(+FFmpeg)} How to queue variable size buffer due to ogg format ?

    11 février 2014, par user3293833

    (First of all, I may feel sorry about my poor English as it's not my native language.)

    I use FFmpeg to decode some audio file and play it with OpenAL by "stream"(i.e."queue" and "unqueue" function of OpenAL).

    When I use my program to play .ogg file, I find that it has a variable nb_samples.(due to ogg has variable bit rate ??) There are 128 B, 512 B and 1024 B of nb_samples. As a results, I must call alDeleteBuffers and alGenBuffers before I use alBufferSamplesSOFT(similar to alBufferData) because it would fail to call alBufferSamplesSOFT without recreate the buffer.
    Notes : alBufferSamplesSOFT is provided by OpenAL Soft. You can just see it as alBufferData.

    Nevertheless, I think it's foolish and inefficient if I do this. Is there is some smart method ? I paste the part of code :

    while (av_read_frame(...) == 0){
    
  avcodec_decode_audio4(...);
    
  swr_convert(...);  // to convert PCM format from FLTP to FLT
    
  alDeleteBuffers(1, theBuffers[?]);
    
  alGenBuffers(1, theBuffers[?]);
    
  alBufferSamplesSOFT(...);  // put those data into OpenAL buffer
    
}

    if I don't do this, It would failed to update the OpenAL buffer. Is there any method to create a variable size buffer or a big size buffer ? Or is there any method to change the size of buffer ?

    Thanks for you guys.

  • ffmpeg : set the language of an audio stream

    22 juillet 2023, par Steven Van Ingelgem

    I have 3 files : video.mp4, audionl.mp4 & audioeng.mp4.
I tried adding them all together in 1 output.mp4 file like this :

    



    ffmpeg -y -i video.mp4 -i audionl.mp4 -i audioeng.mp4  -map 0:v -map 1:a -map 2:a -metadata:s:a:0 language=nl -metadata:s:a:0 title="NL" -metadata:s:a:1 language=eng  -metadata:s:a:1 title="ENG" -acodec copy -bsf:a aac_adtstoasc -vcodec copy  -movflags faststart output.mp4 2>&1


    



    This is the output I see from ffmpeg :

    As you can see in there : "Stream #0:0(eng)", "Stream #0:1(nl)" & "Stream #0:2(eng)".
So that looks fine.

    



    But when I open it in VLC, I see under Audio tracks :
NL - [English]
ENG - [English]

    



    So I went back to check on ffmpeg with "ffmpeg -i output.mp4" :

    And here they are English again...

    



    Afterwards I tried this :

    



    ffmpeg -y -i audionl.mp4 -c:a copy -metadata:s:a:0 language=nl output.mp4


    



    But also that failed to set the correct language on the output file...
I'm at a loss here and hope someone can help me set these languages correctly.

    



    Thanks a lot !

I don't understand the problem ??
