Windows下用ffmpeg推流失败, 求帮忙

[wuranxu]

说明

环境: Windows10

由于结合flv.js使用的demo, 只给出了macos使用ffmpeg推流的方法, 在windows下-f avfoundation会报错。 去ffmpeg官网查看windows的相关命令, -f dshow和-f gdigrab -i desktop, 其中dshow本机运行时也是会报错。

命令行尝试如下:

• 尝试录屏+推流

ffmpeg -f gdigrab -i desktop -vcodec libx264 -preset ultrafast -acodec libfaac -f flv rtmp://loc alhost/live/test

livego偶尔会提示,2018/06/17 17:19:57 writer.go:49: SendPacket error: closed

• 尝试obs工具

成功, flv.js也能看到本机画面。

• 尝试直接推流

ffmpeg -re -i output.flv -c copy -f flv rtmp://localhost/live/test

虽然ffmpeg没有报错, 但是livego报错了, 提示不支持的格式。

求帮助···会否是视频分辨率大小问题

还有其他问题:

• 我也出现类似问题，请问你的问题解决了吗？

[wuranxu]

没有解决···我暂时没有类似需求，windows的话到时候打算用obs推流，用这个当服务器。用obs是可以的
