Video Streaming & Thunder, VanDyke, NetAnts, etc.

How long haven’t you used Thunder? It was so popular on PC, like Tencent. Tencent is still there, while Thunder is gone. Now most on line videos are provided in streaming way.

FFMPEG.exe is a tool to download them. It runs in command line:
ffmpeg -i http://***/***.m3u8 “***.mp4”
And there is a better tool to do such streaming, which is N_m3u8DL-CLI_v2.9.7.exe

How to find the streaming address? Press F12 when you watch video via browser; locate “network” and search for “m3u8”
By this way, you are able to download most videos as long as you are able to watch them in your browser.

While sometimes, there is inhibition for you to complete full streaming, then you need to merge the “.ts” files by yourself.
Way 1
copy /b *.*    output.mp4
Way 2
DIR *.*  /B >filelist.txt
Open filelist.txt using Excel; insert one column before the column of file name; save as txt.
ffmpeg -f concat -safe 0 -i filelist.txt -c copy output.mp4

喜欢编程的人总会很积极地去找到答案,想到各种解决办法。其实在任一个研究领域都是类似的,是否适合做研究是能够感觉得出来的,你自己知道,你的合作者也知道。

这个时代的网络,已经变化很大了,其中之一就是对PC端越来越不友好。迄今,已经见过好几个官网升级之后,PC端浏览器显示界面都不正常,不得已用了手机端。这种感觉就像上个世纪,好多官网只适配IE,又如,现在一些网站仍然依赖flash。
