HLS Remote Server–FTP or SFTP Transfer

The specific parameters for this mode are:

Transfer Protocol:

This configures the protocol to be used between the encoder and the

web server for uploading the files. The two options covered in this section are

FTP

and

SFTP

(Secure FTP). FTP exchanges data and password in the clear, while SFTP

encrypts both flows.

Server Address:

Enter the IP address of the web server here. It needs to be reachable

from either one of the encoder Ethernet ports.

Username:

Enter the username to be used when uploading the files to the server.

Password:

Enter the password corresponding to the user name, to be used when

uploading the files.

Server Path:

Enter the absolute server path for the directory where the files should be

placed. It is recommended that a separate directory be created for each encoder channel.

Base File Name:

Enter the base file name for the files created in the server. The encoder

will create the following files:

o

basename.m3u8:

This is the top playlist file. For the example above, where the

base file name is

live

, the playlist file will be

live.m3u8

. This file will

contain a single bit rate profile. It is created when the encoder starts, and not
changed during operation. For backward compatibility with previous versions, a
top playlist with a

.m3u

extension

and identical contents will also be created.

o

basename_p.m3u8:

This is the current playlist file for the encoder profile. It is

updated every time a new segment is created.

o

basename_XXXX.ts:

These will be the bitstream encoded files. XXXX is an

increasing count. For the example above, the encoder will create files named

live_1.ts

,

live_2.ts

,

live_3.ts

,

live_4.ts

, and so on. At any

given point in time, there will be five or six consecutive files in the configured
directory if the encoder is configured to remove older files.

Extra Server Compatibility:

Check this box if the encoder has problems renaming files

in the server. This is typically required for Windows FTP servers. Linux-based servers
do not need this.

Keep Segments on Server:

Normally, when a segment falls out of the playlist file, it is

automatically deleted by the encoder. If you check this box, the bitstream is left in the
server. Clients will still start playing from the first segment in the playlist.
