ChaseDecrypt - Decrypt while recording


ChaseDecrypt runs whilst a recording is in progress allowing remote access to a programme via file Sharing and a media player like VLC.

This package is experimental and is not intended to be a replacement for Auto Decrypt

You can choose that all programmes for specified channels are processed using the Channel inclusion list or just certain programs by using the Folder flags

If a programme is selected for both ChaseDecrypt and DetectAds Chaserun then DetectAds will take the precedence.


ChaseDecrypt is in the Advanced Packages catalogue. You may need to press the Show button on the package list to display Advanced packages.

Chaseget, ir and some other packages used by ChaseDecrypt will be installed/upgraded automatically as needed.

ChaseDecrypt needs to be able to decrypt the file itself. For this, the minimum requirement is a network connection and to ensure Content Sharing is enabled via Menu >> Settings >> System >> Internet Setting >> Content Share = On. This setting can be enforced using the bootsettings package.

For more information regarding the need for, and implementation of, decryption see Encryption or Decryption Guide ( forum).

Folder Flags

There is a new folder flag ChaseDecrypt which can be Enabled/Disabled via the Opt+ menu, when a new recording start in a folder with this flag it will be decrypted whilst it records. The flag has no effect on existing recordings.

The Auto Decrypt option should also be specified to provide a backup in case of failure during recording.

Channel inclusion list

Channel inclusion page

No channels are included by default.

You can type a generic matching rule such as 'BBC *' in the left hand or ctrl-click on specific channels and then click the ← button to transfer them to the left column. * would match all channels,

To remove entries from the left column position the cursor and use delete or backspace keys.

Thumbnail Generation

If you have the thumbnails package to generate thumbnail image following autodecryption that will not be triggered when using ChaseDecrypt. Instead you can use the Sweeper rule shown below to trigger thumbnail generation.
