java中使用Xuggler获得视频信息,包括文件大小,屏幕分辨率等(Java uses Xuggler to get video information)

随着无线mesh网络的普及，其规模和复杂程度持续发展。然而多跳的mesh网络遇到越来越多的难题，比如带宽降低，无线干扰以及网络时延等。譬如，在网络中的每一跳吞吐量会下降多达50％，连续多跳情况下吞吐量下降得更迅速，其结果将导致网络性能的严重降低。在语音和视频应用大量运行的极端情况下，时延和RF干扰将达到不可接受的程度，而导致连接完全中断(wireless mesh network with the popularity of its size and complexity of sustainable development. However, multi-hop mesh networks encountered more and more problems, such as lower bandwidth, wireless interference and network delay, and so on. For example, in each of the network throughput would drop jump up to 50%, for a number of cases jumped more rapid decline in throughput, The results will lead to serious network performance lower. In voice and video applications running of a large number of extreme cases, delay and RF interference will reach an unacceptable level. which led to the link severed)

使用qt实现网络爬虫，爬取自己感兴趣的图片。原理是采集地址，然后存数据，再去下载。(Use QT to achieve web crawler and crawl pictures that you are interested in. The principle is to collect addresses, then store data, and then download them.)
