rtmp 流的 ffmpeg 覆盖，fname 为空
ffmpeg coversion for rtmp stream, fname empty
我想为 NGINX rtmp 模块使用 HLS_Variant 功能。
但是，如果我按照文档中的示例进行操作，我将无法正常工作。
我有以下测试：
application Test {
live on;
record off;
on_publish http://127.0.0.1/php/rtmp_auth.php;
on_publish_done http://127.0.0.1/php/on_publish_done.php;

application Z006 {

hls_nested on;

hls_variant _src BANDWIDTH=4096000; # _src - Source bitrate, source resolution
}
如您所见，这并没有什么特别之处。

我认为错误显然是 Empty 'fname'。
但是我不知道该怎么办？
编辑：
即使我将 $name 更改为我在 OBS 中使用的 Streamname，转换也不会开始。
我想我成功了。
经过几天的调试支持测试和重建后，我发现了问题。
当您使用以下组合时全部开始：
- on_publish
- 执行
- php-fpm
on_publish 请求首先通过 php-fpm 处理。它产生以下日志：

如您所见，fastcgi 将 http 代码设置为 302，位置为“/”。
此位置是用于执行的 $name 变量！
所以我们必须强制这个 Location 成为我们的流名称。
示例rtmp_auth.php
<?php
$streamName = $_POST["name"];
//Check for streamkey here
//If okay, set Location and Return Code (Set 403 if Auth failed)
header('Location: '.$streamName, TRUE, 200);
?>
在我们手动设置新位置后，日志更改为：

现在 $name 变量已设置为下次与 exec 命令一起使用。

我认为错误显然是 Empty 'fname'。 但是我不知道该怎么办？
编辑：
即使我将 $name 更改为我在 OBS 中使用的 Streamname，转换也不会开始。
我想我成功了。
经过几天的调试支持测试和重建后，我发现了问题。
当您使用以下组合时全部开始：
- on_publish
- 执行
- php-fpm
on_publish 请求首先通过 php-fpm 处理。它产生以下日志：

如您所见，fastcgi 将 http 代码设置为 302，位置为“/”。
此位置是用于执行的 $name 变量！
所以我们必须强制这个 Location 成为我们的流名称。
示例rtmp_auth.php
<?php
$streamName = $_POST["name"];
//Check for streamkey here
//If okay, set Location and Return Code (Set 403 if Auth failed)
header('Location: '.$streamName, TRUE, 200);
?>
在我们手动设置新位置后，日志更改为：

现在 $name 变量已设置为下次与 exec 命令一起使用。 我希望有人可以使用此信息节省一些测试时间。
