【已解决】Mac中如何下载m3u8为单独的视频文件

Mac crifan 2248浏览 0评论

折腾:

【已解决】爬取nickjr.com中的动画片相关视频字幕等数据

期间,需要想办法去下载m3u8为单独的,比如mp4的视频文件

所以再去搜:

m3u8如何下载

直播流m3u8网页怎么下载? – 知乎

有各种下载器

后者用ffmpeg

m3u8视频下载方法_HHeOnline_新浪博客

论如何下载一个在线的m3u8文件到本地成为一个mp4! – 51CTO.COM

“什么是 m3u8

说到 m3u8 就要先说说 HLS(HTTP Live Streaming)。HLS 是 Apple 公司针对 iPhone、iPod、iTouch 等移动设备,而研发的基于 HTTP 协议的流媒体解决方案。在 HLS 技术中,Web 服务器可以向客户端提供接近实时的音视频流,但是它又是使用的标准的 HTTP 协议。所以基本上,比较大型的点播直播类服务,都是基于 HLS 的。

而该技术的原理,就是将视频文件或者视频流,进行切片(ts文件),并建立索引文件(m3u8),它支持的视频流编码为 H.264,音频流编码为 AAC。

简单来说,基于 HLS 的视频流,会将完整的视频,切割成一个个比较小的视频片段(ts 文件),然后根据协议组合成一个 m3u8 文件。这些比较小的 ts 文件,是可以单独播放的。而视频播放器,拿到 m3u8 文件之后,根据对其内 ts 片段的索引,连续播放不同的视频片段,来达到流畅的播放效果。”

mac中去安装ffmpeg

下载期间,速度很慢啊:

下载了好多分钟,才下载了4多分钟的视频:

最后终于下载完毕了。。。

结果是115MB的视频

的确够大。

【后记 2018-03-23】

后来遇到:

希望在输出的文件名中包含子文件夹,或者是完整路径。不知道具体写法。

猜测是直接放在双引号中即可。

但是还是去搜搜:

ffmpeg 指定输出路径

ffmpeg 命令行的输出文件的路径该怎么写??_百度知道

“路径中出现空格或其他空白符时,则需要用双引号把路径包括起来。

比如 “d:\path\my file.mp4””

的确是这个做法。

所以意思就是:

<code>ffmpeg -i url "full_path"
</code>

举例:

<code>ffmpeg -i https://cp450888-vh.akamaihd.net/i/mtvnorigin/gsp.alias/mediabus/kids.com/2016/05/27/05/15/05/dcbc371f6e59467097ec6bd3a162ba90/1194502/vqIve0Tr0p_HDSHS201A2_1194502_6386982_,384x216_278,512x288_498,640x360_1028,768x432_1528,960x540_2128,1280x720_3128,1920x1080_5128,.mp4.csmil/master.m3u8\?hdnea\=st%3D1521162845%7Eexp%3D1521177245%7Eacl%3D%2Fi%2Fmtvnorigin%2Fgsp.alias%2Fmediabus%2Fkids.com%2F2016%2F05%2F27%2F05%2F15%2F05%2Fdcbc371f6e59467097ec6bd3a162ba90%2F1194502%2FvqIve0Tr0p_HDSHS201A2_1194502_6386982_%2C384x216_278%2C512x288_498%2C640x360_1028%2C768x432_1528%2C960x540_2128%2C1280x720_3128%2C1920x1080_5128%2C.mp4.csmil%2F\*%7Ehmac%3Dd383f1d909eabecd89f13d275dca13c0bd733cc0189f62f10f4ae5a6a96149ca\&amp;__a__\=off\&amp;__b__\=450\&amp;__viacc__\=NONE "/Users/crifan/Downloads/nickjr.com/Shimmer and Shine S2 Welcome to Zahramay Falls Ep201 Full Episode.mp4"
