Description

The customer’s current codec policy is already set to ‘for active changing region,’ and there are no further optimizations available in the graphics policy. Since the issue only occurs on the Linux thin client, the customer is asking whether there are any adjustments that can be made in LCWA.

Cause

On the Linux workspace, the customer is using JPEG decoding instead of H.264.

  • JPEG: Compresses each image/frame individually. Simple, good quality for single pictures, but very large if used for video.

  • H.264: Video codec that compresses across frames, only stores changes. Much smaller for motion, efficient for streaming, but needs more CPU/GPU power.

 

Resolution

Enable H264 decode on Linux Workspace client.

In the wfclient.ini file, set H264Enabled to True. 

Issue/Introduction

When the customer opens a webpage with animated images, it works fine on the Windows client, but it is very slow on the Linux thin client.
