Notice

• If you want to check logs, you must use Init() method in Run() method.

• Due to the security issue(fakepath) on the web, the process will copy a stored data received from the web client, then encode it and send it to the ftp server. Therefore, this process must need to delete a stored data and encoded data on local.

• You can stop to encoding a file, but you can't stop during uploading.

• You can set the output directly to the ftp server during the ffmpeg encoding process, but it is not recommended.

• the ftp server's file structure is

    /GoTest/cource_code/cource_number.mp4
