随着视频相关技术的成熟发展与终端设备性能的提升，用户通过相应的视频应用就可以对视频进行处理，其中，相应的视频应用中提供了多种对视频进行处理的方式，如添加滤镜、添加道具、美颜处理等，以此来提升制作的视频的趣味性与个性化。
目前，用户在对视频进行处理时，需要人工筛选确定对视频进行处理的相应处理方式的具体处理参数配置，即用户需要人工筛选确定使用相应视频处理方式的何种处理参数配置，如确定使用何种模式的滤镜、何种类型的道具、何种美颜方式等，对视频进行处理。
然而，根据现有的人工筛选确定相应视频处理方式的具体处理参数配置的方式，需要用户人工从相应视频处理方式包括的大量处理参数配置(如滤镜处理方式中可以包含自然、清新等多种不同的处理参数配置)中进行逐一筛选，才能确定出使用何种处理参数配置对视频进行处理，造成用户需要花费大量的时间才能确定相应视频处理方式的具体处理参数配置。此外，由于部分用户缺乏相关专业知识，会出现选择确定的视频处理 方式之间的具体处理参数配置的风格不统一或不匹配的问题。因此，现有的人工筛选确定相应视频处理方式的具体处理参数配置的方式存在时间成本较高，且用户体验较低的问题，以及存在确定的各种处理方式之间的具体处理参数配置的风格不匹配或不统一的问题。

对于本实施例，可以选择添加相应的目标音乐对目标视频进行处理，如可以作为目标视频进行播放时的背景音乐；其中，该目标视频可以是用户已经拍摄完成的视频，如可以是用户从本地的视频库中确定出来的相应视频，也可以是实时拍摄的视频，如可以是用户在选择相应目标音乐之后，进行实时视频拍摄得到的视频。
对于本实施例，通过相应的音乐类型识别方法确定针对目标视频选定的目标音乐的类型。
步骤S102，基于目标音乐的类型，确定相匹配的视频处理参数，并将视频处理参数作为对目标视频进行处理的推荐信息进行推送。
具体地，可以根据目标音乐的类型与视频处理参数之间的匹配映射关系，基于目标音乐的类型，确定出相匹配的对目标视频进行处理的视频处理参数。
具体地，将确定出的视频处理参数作为对目标视频进行处理的推荐信息进行推送。
在本公开的以上实施例中，根据目标音乐的类型确定相匹配的视频处理参数，并将确定的视频处理参数作为对目标视频进行处理的推荐信息进行推送，避免用户从大量候选视频处理参数信息中进行逐一筛选才能确定 对视频处理的视频处理参数信息，从而减少了用户确定视频处理参数信息所花费的时间，提升了用户的使用体验，此外，目标音乐与相应视频处理参数信息之间的风格相匹配，进而保证了对目标视频进行处理的各处理方式之间的风格的统一，提升了制作的视频的观赏体验。
本公开的实施例提供了一种可能的实现方式，具体地，步骤S101包括：
步骤S1011(图中未示出)，通过预定的语音识别方法确定目标音乐的音乐特征。
具体地，可以通过相应的音频提取技术提取目标音乐的音频信息，通过预定的语音识别方法对目标音乐进行识别，确定目标音乐的音乐特征，其中，目标音乐的音乐特征可以包括但不限于目标音乐的节奏特征、旋律特征、音乐快慢特征等。
步骤S1012(图中未示出)，根据目标音乐的音乐特征，确定目标音乐的类型。
具体地，根据识别确定的目标音乐的音乐特征确定目标音乐的类型，如，爵士乐讲究即兴，以具有摇摆特点的Shuffle节奏为基础，如果识别确定的目标音乐的音乐节奏特征具有Shuffle节奏的特点，则目标音乐为爵士乐，其中，目标音乐的类型可以包括但不限于爵士乐、摇滚乐、乡村音乐、纯音乐、进行曲、朋克等。
对于本公开的实施例，通过预定的语音识别方法确定目标音乐的音乐特征，然后根据目标音乐的音乐特征确定目标音乐的类型，解决了目标音乐的类型的确定问题，为后续基于目标音乐的类型确定相匹配的视频处理参数信息提供了基础。
本公开的实施例提供了一种可能的实现方式，具体地，步骤S1011包括：
步骤S10111(图中未示出)，对提取到的目标音乐的音频数据进行音符切分处理，以得到多个音符片段数据。
具体地，可以通过相应的有音无音判断和前置滤波等技术对目标音乐 的音频数据进行预处理，以去除不包含目标信息的部分以及加强信号并抑制背景噪声。
具体地，可以通过基于高斯低通的FIR滤波器或能实现本公开的其他方法，对目标音乐的音频数据进行处理，以得到PCM格式的目标音乐信号的包络线，然后通过相应的时频分析方法进行峰值检测，确定目标音乐的音符位置。具体地，可以根据确定的目标音乐的音符位置对目标音乐的音频数据进行音符切分处理，以得到多个音符片段数据。
步骤S10112(图中未示出)，基于预定的频谱分析方法对各个音符片段数据进行分析得到各个音符的音符特征。
具体地，可以基于预定的频谱分析方法，如时频分析方法，对各个音符片段数据进行分析，以得到各个音符的过零率、短时能量等声学特征信息，然后根据各个音符的声学特征信息确定各个音符的音符特征，其中，音符的音符特征包括但不限于音符的音高、音强、音色、音长等特征。
步骤S10113(图中未示出)，基于各个音符的音符特征确定目标音乐的音乐特征。
具体地，可以根据各个音符的音高、音强、音色、音长等特征确定目标音乐的音乐特征，如，节奏是指用强弱组织起来的音的长短关系，节奏不仅与音的长短有关系，而且与音的强弱有关系，可以根据音符的音长与音强特征确定目标音乐的节奏特征。
对于本公开的实施例，通过确定目标音乐的各个音符的特征确定目标音乐的音乐特征，解决了目标音乐的音乐特征的确定问题，从而为目标音乐类型的确定提供了基础。
本公开的实施例提供了一种可能的实现方式，进一步地，该方法还包括：
