New policies for Linux VDA

The following policies can be configured in version 7.12 of Citrix Studio.   

Max Speex Quality

Applies to: Linux VDA 1.4 and later

Scope:

Value (integer): [0 - 10]

Use default value: 5 

Details:

Audio redirection encodes audio data with the Speex codec when audio quality is medium or low (see the policy Audio quality). Speex is a lossy codec, which means that it achieves compression at the expense of fidelity of the input speech signal. Unlike some other speech codecs, it is possible to control the tradeoff made between quality and bit rate. The Speex encoding process is controlled most of the time by a quality parameter that ranges from 0 to 10. The higher the quality is, the higher the bit rate.

The max Speex quality chooses the best Speex quality to encode audio data according to audio quality and bandwidth limit (see the policy Audio redirection bandwidth limit). If the audio quality is medium, the encoder is in wide band mode, which means a higher sampling rate. If the audio quality is low, the encoder is in narrow band mode, which means a lower sampling rate. The same Speex quality has different bit rates in different modes. The best Speex quality is when the largest value meets the following conditions:

  • It is equal to or less than the max Speex quality
  • Its bit rate is equal to or less than the bandwidth limit

Primary Selection Update Mode

Applies to: Linux VDA 1.4 and later

Scope:

Value (enum): [0, 1, 2, 3]

Use default value: 3

Details:

PRIMARY selection is used for explicit copy/paste actions such as mouse selection and middle mouse button paste. This setting controls whether PRIMARY selection changes on the Linux VDA can be updated on the client’s clipboard (and vice versa). It can include one of the following selection changes:

  • Selection changes are not updated on the client or the host.
    PRIMARY selection changes do not update a client’s clipboard. Client clipboard changes do not update PRIMARY selection.
  • Host selection changes are not updated on the client.
    PRIMARY selection changes do not update a client’s clipboard. Client clipboard changes update the PRIMARY selection.
  • Client selection changes are not updated on the host.
    PRIMARY selection changes update the client’s clipboard. Client clipboard changes do not update the PRIMARY selection.
  • Selection changes are updated on both the client and host.
    PRIMARY selection change updates the client’s clipboard. Client clipboard changes update the PRIMARY selection.

Clipboard Selection Update Mode

Applies to: Linux VDA 1.4 and later

Scope:

Value (enum): [0, 1, 2, 3]

Use default value: 3

Details:

This setting controls whether CLIPBOARD selection changes on the Linux VDA are updated on the client’s clipboard (and vice versa). It can include one of the following selection changes:

  • Selection changes are not updated on the client or the host.
    CLIPBOARD selection changes do not update a client’s clipboard. Client clipboard changes do not update CLIPBOARD selection.
  • Host selection changes are not updated on the client.
    CLIPBOARD selection changes do not update a client’s clipboard. Client clipboard changes update the CLIPBOARD selection.
  • Client selection changes are not updated on the host.
    CLIPBOARD selection changes update the client’s clipboard. Client clipboard changes do not update the CLIPBOARD selection.
  • Selection changes are updated on both the client and host.
    CLIPBOARD selection change updates the client’s clipboard. Client clipboard changes update the CLIPBOARD selection.
