FFmpeg是一套可以用来记录、转换数字音频、视频，并能将其转化为流的开源计算机程序。采用LGPL或GPL许可证。它提供了录制、转换以及流化音视频的完整解决方案。它包含了非常先进的音频/视频编解码库libavcodec，为了保证高可移植性和编解码质量，libavcodec里很多code都是从头开发的。
FFmpeg在Linux平台下开发，但它同样也可以在其它操作系统环境中编译运行，包括Windows、Mac OS X等。这个项目最早由Fabrice Bellard发起，2004年至2015年间由Michael Niedermayer主要负责维护。许多FFmpeg的开发人员都来自MPlayer项目，而且当前FFmpeg也是放在MPlayer项目组的服务器上。项目的名称来自MPEG视频编码标准，前面的"FF"代表"Fast Forward"。 [1] FFmpeg编码库可以使用GPU加速。
FFmpeg is an open source computer program that can be used to record, convert digital audio and video, and convert them into streams. Use LGPL or GPL license. It provides a complete solution for recording, converting, and streaming audio and video. It contains a very advanced audio/video codec library libavcodec. In order to ensure high portability and codec quality, many codes in libavcodec are developed from scratch.
FFmpeg is developed under the Linux platform, but it can also be compiled and run in other operating system environments, including Windows, Mac OS X, etc. This project was first initiated by Fabrice Bellard, and was mainly maintained by Michael Niedermayer from 2004 to 2015. Many FFmpeg developers come from the MPlayer project, and currently FFmpeg is also placed on the server of the MPlayer project team. The name of the project comes from the MPEG video coding standard, and the preceding "FF" stands for "Fast Forward". [1] FFmpeg encoding library can use GPU acceleration.
If we see a good m3u8 stream, how to merge it into an mp4 file?
Good guys, there are almost no useful tools on the entire network, even if there are shells, the fee is really speechless, and I have found a lot of chrome browser plug-ins. There is almost no useful tool. Even if it is a cat, after some testing, it can only be explored for m3u8 The address cannot be synthesized and downloaded!
Then we invite the veteran and originator software ffmpeg in the video editing industry. It can be said that there are video conversion software with graphical interfaces on the market. What format, factory, and various video conversion software. 99% of the cores are shell software synthesized by ffmpeg. The awesomeness cannot be expressed in words, but today we only used one sentence command to complete the download and synthesis of m3u8 in one go. It is of course not 100% able to get the mp4 file directly for you. It is estimated that it will not work. One sentence command example And the github sources are all below. In order to prevent flooding, this blog is set to charge. Of course, you can check it for free after logging in for a week. Come on!
如果我们看到一个不错的m3u8流媒体 如何合并成mp4文件?
好家伙 全网几乎没有好用的工具 即使有也是套壳 收费 实在是无语
chrome浏览器插件也找了非常多 几乎没有一个好用的 即使是猫抓 经过一番测试 也只能是探索出m3u8的地址 无法合成和下载！
那么我们请出视频编辑界的元老和鼻祖软件 ffmpeg
可以说现在市面上有图形化界面的视频转换软件 什么格式工厂 什么狸猫 各种视频转换软件 99%内核都是用ffmpeg合成的套壳软件
这个软件 牛逼之处无法用语言表达 而我们今天只用一句话命令 就搞定了 m3u8的下载和合成 一气呵成 直接mp4文件给你搞下来
当然也不是100%能搞定 加密过的估计就不行了
一句话命令 范例及github来源 都在下面了 为了防止泛滥成灾 本博设置收费 当然您登陆后连续签到一周 就可以免费查看了 加油！
