  • ffmpeg after converting avi to mp4 need wait till video loads in flash player 100% otherwise video is buffering

    28 octobre 2013, par Xenos Trojanowicz

    So if fixed all issues with my ffmpeg journey now I just need that after converting videos they play in flash player instantly and no need to wait till video loeaded 100% I use :

    if ($success_msg) {

        $convert_source = _VIDEOS_DIR_PATH.$new_name;
    
        $conv_name = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
    
        $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
