我试图使用phantomjs创建视频流,从网址创建截图,然后它将框架管道到ffmpeg,以便他可以使用它将视频流传输到rtmp网址.这是我到目前为止所尝试的:
phantomjs runner.js | ffmpeg -f image2pipe -vcodec png -c:a copy -c:v libx264 -f flv rtmp://localhost/mystream
这是脚本:
var page = require('webpage').create();
page.viewportSize = { width: 640, height: 480 };
page.open('http://www.goodboydigital.com/pixijs/examples/12-2/', function () {
setInterval(function() {
page.render('/dev/stdout', { format: "png" });
}, 25);
});
这是输出:

libavutil 55. 17.103 / …这是我的fql:
$fql = "SELECT uid, name, online_presence, status
FROM user
WHERE uid IN ( SELECT uid2 FROM friend WHERE uid1 = '".$user_id."') ";
该online_presence值总是返回null.
我安装了Windows 8.1然后我重新安装wampserver,一切正常..直到我得到橙色,由于我的MySQL服务器没有运行....
Wampserver 2.4
MySQL 5.6.12
PHP 5.4.12
Apache 2.4.4
这是日志文件
