你如何使用youtube-dl下载直播(现场直播)？

Question

只是想知道是否可能 - 当我将视频网址复制到YouTube-dl时,它会吐出来

[https @ 0x7fc351416080] inflate return value: -3, incorrect header check
Last message repeated 15 times

在那之后,它吐出了几行似乎不想正确复制的红色文本,所以我拿了一个片段

有谁知道这是否可能？

Answer 1

我将以此直播活动为例:

https://www.youtube.com/watch?v=6aXR-SL5L2o

首先,列出视频的格式:

$  ~ youtube-dl --list-formats https://www.youtube.com/watch\?v\=6aXR-SL5L2o
[youtube] 6aXR-SL5L2o: Downloading webpage
[youtube] 6aXR-SL5L2o: Downloading video info webpage
[youtube] 6aXR-SL5L2o: Extracting video information
[youtube] 6aXR-SL5L2o: Downloading formats manifest
[youtube] 6aXR-SL5L2o: Downloading MPD manifest
[info] Available formats for 6aXR-SL5L2o:
format code  extension  resolution note
91           mp4        144p       HLS , h264, aac  @ 48k
92           mp4        240p       HLS , h264, aac  @ 48k
93           mp4        360p       HLS , h264, aac  @128k
94           mp4        480p       HLS , h264, aac  @128k
95           mp4        720p       HLS , h264, aac  @256k (best)

选择您要下载的格式,然后从清单中获取视频的HLS m3u8 URL.我将95 mp4 720p HLS , h264, aac @256k用于这个例子:

?  ~ youtube-dl -f 95 -g https://www.youtube.com/watch\?v\=6aXR-SL5L2o

现在,你有HLS播放列表,您可以在VLC打开这个网址,并使用"记录"保存它,或者写一个小的ffmpeg的命令:

ffmpeg -i \

-c copy output.ts

Answer 2

没有必要传递任何东西ffmpeg你可以只获取所需的格式,在这个例子中,它是"95"格式.

所以一旦你知道它是95,你只需输入:

youtube-dl -f 95  https://www.youtube.com/watch\?v\=6aXR-SL5L2o

也就是说:

youtube-dl -f <format number> <url>

它将开始在工作目录上生成一个<somename>.<probably mp4>.part部分下载的文件,让它去,然后按下<Ctrl-C>以停止捕获.

该文件仍将被命名<something>.part,重命名<whatever>.mp4为... 它在那里...

该ffmpeg代码:

ffmpeg -i $(youtube-dl -f <format number> -g <url>) -copy <file_name>.ts

也适合我,但声音和视频不同步,使用youtube-dl似乎只会产生更好的结果,虽然它也使用ffmpeg.

这种方法的缺点是你在下载时无法观看视频,你可以打开另一个FF或Chrome,但似乎mplayer无法处理视频输出直到youtube-dl/ ffmpeg正在运行.

一些带有 m3u 流媒体的网站无法youtube-dl一步下载，您可以尝试这样的操作：

$ URL=https://www.arte.tv/fr/videos/078132-001-A/cosmos-une-odyssee-a-travers-l-univers/
$ youtube-dl -F $URL | grep m3u
HLS_XQ_2     m3u8       1280x720   VA-STA, Allemand 2200k
