1. 网页上的视频怎么下载
需要工具：电脑、浏览器
一、首先，我们打开一个视频网页，如图
/iknow-pic.cdn.bcebos.com/d1a20cf431adcbef44a0789ca2af2edda2cc9f97"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/d1a20cf431adcbef44a0789ca2af2edda2cc9f97?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/d1a20cf431adcbef44a0789ca2af2edda2cc9f97"/>
二、在页面内按"F12"或者点击右上角的：三个点-更多工具-开发者工具
/iknow-pic.cdn.bcebos.com/adaf2edda3cc7cd9b5b932433701213fb90e9197"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/adaf2edda3cc7cd9b5b932433701213fb90e9197?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/adaf2edda3cc7cd9b5b932433701213fb90e9197"/>
三、就可以看到如图的网页源代码了
/iknow-pic.cdn.bcebos.com/5d6034a85edf8db1baa256fe0723dd54574e749f"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/5d6034a85edf8db1baa256fe0723dd54574e749f?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/5d6034a85edf8db1baa256fe0723dd54574e749f"/>
四、此时需要点击“sourece”，然后在右边的文件栏里面挨着挨着点开寻找，找到如图的这种代码；
/iknow-pic.cdn.bcebos.com/e1fe9925bc315c605a19417583b1cb134854779f"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/e1fe9925bc315c605a19417583b1cb134854779f?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/e1fe9925bc315c605a19417583b1cb134854779f"/>
五、这种代码以“ src="”，其后是以“http:”开始的一个类似网址的链接，链接以“.swf”结尾，整个这个链接就是我们要的视频在服务器上的储存地址
/iknow-pic.cdn.bcebos.com/a2cc7cd98d1001e903a81295b60e7bec55e79797"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/a2cc7cd98d1001e903a81295b60e7bec55e79797?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/a2cc7cd98d1001e903a81295b60e7bec55e79797"/>
六、复制这个链接到浏览器打开或者到你的下载软件中打开，就可以下载网页中的视频了
/iknow-pic.cdn.bcebos.com/5243fbf2b21193139eb2e32a6b380cd790238db2"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/5243fbf2b21193139eb2e32a6b380cd790238db2?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/5243fbf2b21193139eb2e32a6b380cd790238db2"/>
2. 如何从网页上下载前缀是https视频
http和httpss是两种不同的协议，如果网页使用https，是用了ssl加密的方式打开网页，所以不能去掉https，如果去掉https，默认的协议是http，就无法正常打开经过ssl加密的网页了
3. 有什么办法可以把网页上面不能下载的视频弄下来
可以通过网页视频的源代码网址进行下载，具体步骤如下：
1、首先打开一个视频网页点击右上角的：三个点-更多工具-开发者工具，如图所示：
/iknow-pic.cdn.bcebos.com/91ef76c6a7efce1be51dfbc7a051f3deb48f658c"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/91ef76c6a7efce1be51dfbc7a051f3deb48f658c?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/91ef76c6a7efce1be51dfbc7a051f3deb48f658c"/>
2、然后选择SOURCES，如下图所示：
/iknow-pic.cdn.bcebos.com/e61190ef76c6a7efb6c4982bf2faaf51f2de66d8"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/e61190ef76c6a7efb6c4982bf2faaf51f2de66d8?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/e61190ef76c6a7efb6c4982bf2faaf51f2de66d8"/>
3、选择后可以看到网页源代码，如下图所示：
/iknow-pic.cdn.bcebos.com/a1ec08fa513d269744e23b505afbb2fb4316d88d"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/a1ec08fa513d269744e23b505afbb2fb4316d88d?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/a1ec08fa513d269744e23b505afbb2fb4316d88d"/>
4、此然后在右边的文件栏里面挨着挨着点开寻找，找到以“ src=”开头的代码，如下图所示：
/iknow-pic.cdn.bcebos.com/7dd98d1001e93901461fbe3374ec54e736d19699"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/7dd98d1001e93901461fbe3374ec54e736d19699?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/7dd98d1001e93901461fbe3374ec54e736d19699"/>
5、以“ src="”，其后是以“http:”的链接，链接以“.swf”结尾就是我们要的视频在服务器上的储存地址，如下图所示：
/iknow-pic.cdn.bcebos.com/d53f8794a4c27d1e6cc20bc914d5ad6edcc438d2"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/d53f8794a4c27d1e6cc20bc914d5ad6edcc438d2?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/d53f8794a4c27d1e6cc20bc914d5ad6edcc438d2"/>
六、复制这个链接到浏览器打开或者到你的下载软件中打开，就可以下载网页中的视频了，如下图所示：
/iknow-pic.cdn.bcebos.com/c8ea15ce36d3d539f0fb3fce3587e950342ab0fc"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/c8ea15ce36d3d539f0fb3fce3587e950342ab0fc?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/c8ea15ce36d3d539f0fb3fce3587e950342ab0fc"/>
4. 网页中的视频怎么下载下来啊求助！
1.把你看的视频先缓冲完或者看完也可以。
2.点击网页最上面一拦的“工具”，然后找到“Internet选项”。
/iknow-pic.cdn.bcebos.com/4ec2d5628535e5dd34de39157ac6a7efcf1b620e"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/4ec2d5628535e5dd34de39157ac6a7efcf1b620e?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/4ec2d5628535e5dd34de39157ac6a7efcf1b620e"/>
打开工具——Internet选项
3.点击“Internet选项”，找到“设置”。
/iknow-pic.cdn.bcebos.com/738b4710b912c8fcd76a6a07f0039245d788215a"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/738b4710b912c8fcd76a6a07f0039245d788215a?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/738b4710b912c8fcd76a6a07f0039245d788215a"/>
打开选项
4.单击“设置”，出现下面这样的图框，找到“查看文件”。
5.点击“查看文件”，并在出现的图框内鼠标右键单击——排列图片(I)——大小
/iknow-pic.cdn.bcebos.com/faf2b2119313b07e7b62ccc200d7912396dd8c19"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/faf2b2119313b07e7b62ccc200d7912396dd8c19?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/faf2b2119313b07e7b62ccc200d7912396dd8c19"/>
查看文件
6.由于视频文件比较大，会排在最前面。找到视频文件，直接拉到桌面上就行了。视频文件一般是FLV，MP4格式的，如下面的粉红色框内就是视频文件，不要找错了。接下里就进行网页视频下载了。
/iknow-pic.cdn.bcebos.com/6159252dd42a2834aa38aac157b5c9ea14cebf5a"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/6159252dd42a2834aa38aac157b5c9ea14cebf5a?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/6159252dd42a2834aa38aac157b5c9ea14cebf5a"/>
找FLV视频文件
7.到此基本上完毕。FLV格式的文件MP4/MP5有的能放出来有的放不出来，建议在转换一下格式，转换成高清格式(rmvb，mp4)的。手机转换成3GP格式。推荐转换器：抓抓影音伴侣。小编觉得很好用，强烈推荐，如果下载转换器请到官网进行下载。
5. http://www.youku.com/playlist_show/id_16609406.html加密视频咋下载
首先注册一个优酷账号，然后打开那个加密视频，地址应该是http://v.youku。****，你吧v后面加上xia，变成http://v.xiayouku****，这样应该可以下载，在弹出对话框中输入你的账号和密码，然后下载试试吧……
