  • Copying avcodec parameters

    4 juin 2020, par Ayxan

    I am trying to use libav to convert an MP4 file to an MP3 file. Basically trying to achieve what ffmpeg -i filename.mp4 filename.mp3 does. I've found this official example. But when I run it with an input MP4 and an output MP3 I get an error :

    



    


    Invalid audio stream. Exactly one MP3 audio stream is required.

    


    



    I am not at all familiar with this library but I think I have narrowed the problem down to this line :

    



    ret = avcodec_parameters_copy(out_stream->codecpar, in_codecpar);


    



    It seems to copy all streams for a video file but we only need one for the MP3 file ? I am not sure. There doesn't seem to be a function to copy only the parameters relevant to audio. I checked the sources, avcodec_parameters_copy does a simple memcpy.

    



    Questions :

    



      

    1. Is this the actual problem ?

      2. 


    2. How do I solve it ?

      3. 


    3. Am I on the right track to achieve the goal of extracting audio from a video file ? I've seen this question (and other similar questions like this and this) on here but none seem to have a complete code example. The C API documentation for this library is also a little lacking.

      4.
