• configure : fall back to using full path if src is a directory

  configure : fall back to using full path if src is a directory
  Or when building in-tree.
  
  Also don’t try to remove src on distclean in these cases.

• Configuration of video device failed, falling back to default

  4 février 2021, par hgwd

  I'm writing a program to open my mac osx's facetime hd camera and get h264 data with ffmpeg, but i encounter encounter a hard problem at the first step.

  


  AVFormatContext *Producer::OpenCamera()
{
    AVFormatContext *pContext = avformat_alloc_context();
    AVInputFormat *infmt = av_find_input_format("avfoundation");
    if (infmt != nullptr)
    {
        AVDictionary *paramDict = nullptr;
        av_dict_set(&paramDict, "video_device_index", "1", 0);
        av_dict_set(&paramDict, "video_size", "1280x720", 0);
        av_dict_set(&paramDict, "framerate", "30", 0);
        av_dict_set(&paramDict, "pixel_format", "yuyv422", 0);

        int ret = avformat_open_input(&pContext, "0", infmt, &paramDict);
        if (ret != 0)
        {
            std::cout << "cannot open input" << std::endl;
            avformat_free_context(pContext);
            return nullptr;
        }
    }

    return pContext;
}


  


  When I call the function, I get the result below :

  


  '' opened
Configuration of video device failed, falling back to default.


  


  Addtionally, when I set av_dict_set(&paramDict, "video_device_index", "0", 0) ; I'll get sig abort, which makes me confused. Can anyone help me ?
