  • File input of avformat_open_input in ffmpeg

    28 février 2016, par Justin Chang

    I’m trying to use function avformat_open_input in FFmpeg to open the file which contains Chinese word.

    For example :

    char* file="C:/測試/baby.mp4";
    

    
avformat_open_input(&pFormatCtx, file, NULL, NULL);

    But, it seems to be failed.

    My question is how do I pass the file path which contains Chinese (or other languages except for English) ?

    Question :

    


    How can I ensure that text rendered with fallback fonts has the same size as the main font ? Are there specific settings in FFmpeg or the ASS subtitle format that can address this issue ? Alternatively, is there a way to manually adjust the scaling of fallback fonts in FFmpeg ?
