在ffmpeg中设置useragent

Question

如何在ffmpeg中设置useragent？

我在媒体服务器上实现了SWF验证，并允许一些用户代理不检查SWF。但问题是，我无法在FFMPEG中设置用户代理。因为我需要使用ffmpeg将我的一个低比特率的流传输到核心服务器。

FFMPEG Version : ffmpeg version 1.2.6-7:1.2.6-1~trusty1

SWF verification enabled in 172.20.1.10 server

尝试过的格式：

ffmpeg -re -i "rtmp://10.11.12.13/live/mystreams -c copy -f flv  "rtmp://172.20.1.10/live/testnew -headers "UserAgent: 'FMLE/3.0 (compatible; FMSc/1.0)'"

ffmpeg -re -i "rtmp://10.11.12.13/live/mystreams -c copy -f flv  "rtmp://172.20.1.10/live/testnew -user_agent 'FMLE/3.0 (compatible; FMSc/1.0)'"

ffmpeg -re -i "rtmp://10.11.12.13/live/mystreams -c copy -f flv  "rtmp://172.20.1.10/live/testnew -user-agent 'FMLE/3.0 (compatible; FMSc/1.0)'"

Answer 1

首先，操作尝试有中断的引号：

"... "rtmp://172.20.1.10/live/testnew -user_agent 'FMLE/3.0 (compatible; FMSc/1.0)'"

-user-agent选项已弃用，它将显示警告：

$ ffmpeg  -user-agent "using -user-agent UA"  -i 'https://example.com' -v trace |& grep -i user-agent 
Reading option '-user-agent' ... matched as AVOption 'user-agent' with argument 'using -user_agent UA'.
[https @ 0x55df7b9dc320] the user-agent option is deprecated, please use user_agent option
User-Agent: using -user-agent UA

您需要-user_agent (即下划线_，而不是破折号-)：

$ ffmpeg  -user_agent "using -user_agent UA"  -i 'https://example.com' -v trace |& grep -i user-agent 
User-Agent: using -user_agent UA

如果添加了-headers 'User-Agent: '，它将覆盖-user_agent

$ ffmpeg -user_agent "using -user_agent UA" -headers 'User-Agent: using -headers UA'  -i 'https://example.com' -v trace |& grep -i user-agent 
Reading option '-headers' ... matched as AVOption 'headers' with argument 'User-Agent: using -headers UA'.
User-Agent: using -headers UA

但是，如果在尝试添加多个标头时语法错误，则-headers将无法覆盖，并且仍然使用默认的Lavf/或-user_agent

$ ffmpeg  -user_agent "using -user_agent UA" -headers 'User-Agent: using -headers UA' -headers 'Accept: */*' -i 'https://example.com' -v trace |& grep -i user-agent 
Reading option '-headers' ... matched as AVOption 'headers' with argument 'User-Agent: using -headers UA'.
User-Agent: using -user_agent UA

只有在多个标头上使用正确的语法(即单个-headers + \r\n)，-headers 'User-Agent:才能覆盖默认的Lavf/或-user_agent

$ ffmpeg  -user_agent "using -user_agent UA" -headers 'User-Agent: using -headers UA'$'\r\n''Accept: */*' -i 'https://example.com' -v trace |& grep -i user-agent 
Reading option '-headers' ... matched as AVOption 'headers' with argument 'User-Agent: using -headers UA
User-Agent: using -headers UA

Answer 2

ffmpeg -user-agent "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3554.0 Safari/537.36" -headers "origin: https://glive.gaodun.com" -headers "referer: https://glive.gaodun.com/space.html?isV"  -i https://vod.gaodun.com/13p9Wv580v1a!!fs/SD/1.m3u8 -c copy demo.mp4

Answer 3

-headers 'User-Agent: "FMLE/3.0 (compatible; FMSc/1.0)"'

User agent - Wikipedia

此外，您可能需要包括CRLF：

-headers $'User-Agent: "FMLE/3.0 (compatible; FMSc/1.0)"\r\n'
