1. OBS 来源

来源

主要会用到两个来源,第一个是窗口采集:一般在视频录制的时候,会在在 PC 上进行操作,这个来源就是采集桌面,然后录制进视频。

另一个是视频采集设备,也就是camera,这个的用途是在你想要将自己也录制进视频的时候,就可以增加一个窗口。

添加完这两个来源以后如下所示:

cannot connect to the database successfully

In chainlink node setup, there is a problem:

[ERROR] Cannot boot Chainlink: opening db: failed to open db: failed to connect to `host=/private/tmp user=xxxx database=`: server error (FATAL: unrecognized configuration parameter "?application_name" (SQLSTATE 42704))                                  err=Cannot boot Chainlink: opening db: failed to open db: failed to connect to `host=/private/tmp user=xxxx database=`: server error (FATAL: unrecognized configuration parameter "?application_name" (SQLSTATE 42704)) errVerbose=opening db: failed to open db: failed to connect to `host=/private/tmp user=xxx database=`: server error (FATAL: unrecognized configuration parameter "?application_name" (SQLSTATE 42704))

Usually, this problem is because the Chainlink client cannot get the DATABASE_URL so that cannot connect to the database correctly.

The solution is to set DATABASE_URL as an environment variable by script:

export DATABASE_URL=postgresql://<usrname>:<passswd>@<server>:<port>/<DBName>?sslmode=disable 

Please refer to the official configuration page and this StackOverflow question for more information.

Hope it helps and keep going!
