我想将实时 m3u8 文件重新流式传输到 youtube。我使用了以下代码

fmpeg -re -i <http://mypanel.tv:8080/live/****/slyv0955k9/14131.m3u8
> -c:v copy -c:a aac -ar 44100 -ab 128k -ac 2 -strict -2 -flags +global_header -bsf:a aac_adtstoasc -bufsize 3000k -f flv "<rtmp://live-dfw.twitch.tv/app/{live_231566994_FS4BN0qoJMeXEuWklm6j0l1ODQj9u6}>"

我回来我从我的 linux 服务器得到这个

[root@server ~]# ffmpeg -re -i http://mypanel.tv:8080/live/****/slyv0955k9/14131.m3u8
 -c:v copy -c:a aac -ar 44100 -ab 128k -ac 2 -strict -2 -flags +global_header -bsf:a aac_adtstoasc -bufsize 3000k -f flv "<rtmp://live-dfw.twitch.tv/app/{live_23156556994_FS4BN0qoJMeXEuWklm6j0l1ODQj9u6}>"ffmpeg version 2.6.8 Copyright (c) 2000-2016 the FFmpeg developers

那么任何人都可以帮我解决这个问题吗？请注意我不是 linux 专家，所以请给我特定的命令来重新流式传输实时 m3u8 文件

试试看：

#! /bin/bash

PRESET="ultrafast" # ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow, placebo
SOURCE="http://sample.vodobox.net/skate_phantom_flex_4k/skate_phantom_flex_4k.m3u8"
YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"
KEY="xxxx-xxxx-xxxx-xxxx" # Your youtube key. (https://www.youtube.com/live_dashboard > encoder config > name/key)

ffmpeg \
    -re -i "$SOURCE" -vcodec libx264 -preset $PRESET -maxrate 3000k -b:v 2500k \
    -bufsize 600k -pix_fmt yuv420p -g 60 -c:a aac -b:a 160k -ac 2 \
    -ar 44100 -f flv -s 1280x720 "$YOUTUBE_URL/$KEY"
