篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了支持smil文件的MMS PDU打包方式.相关的知识，希望对你有一定的参考价值。
mms如果不支持smil那就不能叫真正的MMS,mixed的格式对于多个附件的MMS来说不仅没有"排版"功能,
而且即使用你想一个文件一个文件"拆单了看",也不得不看一次手工播放一次,就象要手动"翻页".所以不支持
smil干脆就别玩MMS了.
但基于related格式的支持smil的PDU打包方式怎么也搜索不到,很多厂商和技术人员都故作神秘,不就是一
堆规范的实现吗?只好下了几个文档来研究,经过反复调试,其中用nowSMS的mmscomp打包出来的格式竟然
是错误的,最后多次抓包比较,总算成功了.在『别人原来的mixed方式』的基础上修改成related方式的.有需要的
就自己用去吧.(注意基础类是别人原来提供的,我只是提供了related方式的打包逻辑)
