步骤100：解析预先设置的含有一个视频轨信息和多个音轨信息的视频流片源信息；所述每个音轨信息还包含了语种信息和音频编码格式信息、音频码率信息、声道数信息。如果多个音轨信息中包含了多种语种信息，那么针对每种语种信息对应的音轨信息被筛选出来作为输出音轨信息；如果有两个或两个以上的同一语种具有不同的音频编码格式，那么筛选出音频质量最好的音轨信息作为这种语种对应的输出音轨信息。此处，音频质量最好的判断条件是通过音频编码格式信息、音频码率信息、声道数信息来判断的。
步骤200：在解析出的所述多个音轨信息中筛选出输出音轨信息；
步骤300：对筛选的输出音轨信息的视频流进行转码输出。
本实施例可以看出，通过解析预先设置的含有一个视频轨信息和多个音轨信息的视频流片源信息；在解析出的所述多个音轨信息中筛选出输出音轨信息；最后对筛选的输出音轨信息的视频流进行转码输出。实现了节约视频流存储空间的同时，也节约了视频流传输带宽。
实施例二
参照图2，是本发明一种视频流转码装置的实施例的结构框图。
本实施例所述的一种装置1，包括：片源信息解析单元2、输出音轨筛选单元3、视频流转码单元4。
片源信息解析单元2，用于解析预先设置的含有一个视频轨信息和多个音轨信息的视频流片源信息；
输出音轨筛选单元3，用于根据片源解析单元解析出的所述多个音轨信息中筛选出输出音轨信息；
视频流转码单元4，用于对输出音轨筛选单元筛选的输出音轨信息的视频流进行转码输出。
在本实施例中，所述片源信息解析单元2，还用于解析预先设置的含有一个视频轨信息和多个音轨信息的视频流片源信息，每个音轨信息包含语种信息和音频编码格式信息。
当所述输出音轨筛选单元2针对解析出的多个音轨信息中包含的每个语种信息筛选出一个输出音轨信息。例如，如果多个音轨信息中包含了多种语种信息，那么针对每种语种信息对应的音轨信息被筛选出来作为输出音轨信息；如果有两个或两个以上的同一语种具有不同的音频编码格式，那么筛选出一个音频质量最好的输出音轨信息。此处，音频质量最好的判断条件是通过音频编码格式信息、音频码率信息、声道数信息来判断的。
