  • Reading encoded data using muxing in ffmpeg

    2 mai 2017, par Sanduni Wickramasinghe

    I am trying to read an encoded video using ffmpeg c++. When I try to build my code error appears as identifier options is undefined. But it is already defined as AVDictionary *options = NULL.

    What is wrong with my code ?

    void CFfmpegmethods::VideoRead(){
    

    
    const char *url = "H:/Sanduni_projects/ad_2.mp4";
    

    
    AVFormatContext *s = NULL;
    
    int ret = avformat_open_input(&s, url, NULL, NULL);
    
    if (ret < 0)
    
        abort();
    

    
    avformat_find_stream_info(s, &options);
    

    
    AVDictionary *options = NULL;
    

    
    av_dict_set(&options, "video_size", "640x480", 0);
    
    av_dict_set(&options, "pixel_format", "rgb24", 0);
    

    
    if (avformat_open_input(&s, url, NULL, &options) < 0){
    
        abort();
    
    }
    

    
    av_dict_free(&options);
    

    
    AVDictionaryEntry *e;
    

    
    if (e = av_dict_get(options, "", NULL, AV_DICT_IGNORE_SUFFIX)) {
    
        fprintf(stderr, "Option %s not recognized by the demuxer.\n", e->key);
    
        abort();
    
    }
    

    
    avformat_close_input(&s);
    
}

    x86/intmath : add VEX encoded versions of av_clipf() and av_clipd()

    Prevents mixing inlined SSE instructions and AVX instructions when the compiler
    
generates the latter.
