HDX RealTime Webcam Video Compression limitations

• Camera with hardware encoding is not supported in ThinOS.
• Since x264 library is not integrated into ThinOS, 64-bit apps with HDX RealTime Webcam Video Compression are not supported by Citrix Workspace App. Hence, only 32-bit apps with HDX RealTime Webcam Video Compression are supported in ThinOS.
• Citrix Workspace App 2112 with HDX RealTime Webcam Video Compression works only with built-in camera. The issue is also reproduced in Linux Citrix Workspace app binary. Hence, from this ThinOS release, HDX RealTime Webcam Video Compression is only supported with Citrix Workspace app 2109.
• Sometimes, the updated Camera Width, Camera Height and Camera FPS settings does not sync from Wyse Management Suite to the thin client. You must reboot the client for the changes to take effect.
• HDX RealTime Webcam Video Compression in ThinOS supports only one webcam at a time. Citrix Workspace Linux binary can update the default webcam by modifying HDXWebCamDevice in $HOME/.ICAClient/wfclient.ini configuration file. For example, add HDXWebCamDevice=/dev/video2 to set the webcam mapped to /dev/video2 in a system. However, ThinOS does not allow to input the value /dev/video2 in VDI Configuration Editor due to security reasons.
• If client camera is set to 2304x1296 or 2304x1536 video resolution, the HDX webcam redirection cannot be previewed in the session. This limitation is reproduced in CWA 2109 Linux binary as well.
• If client camera is set to 1920x1080 video resolution, the HDX webcam redirection falls back to 325x288 video resolution in the session. This limitation is reproduced in CWA 2109 Linux binary as well.
• HDX webcam camera sometimes does not work on Webex Meeting call. This limitation is reproduced in CWA 2109 Linux binary as well.
• Zoom application video preview sometimes fails when you use Citrix HDX Webcam. This limitation is reproduced in CWA 2109 Linux binary as well.
• Webex application video fails to preview when you use Citrix HDX Webcam. This limitation is reproduced in CWA 2109 Linux binary as well.
• External USB camera does not work with Citrix HDX Webcam in Citrix Workspace app 2112. Only the built-in camera works. This limitation is reproduced in CWA 2109 Linux binary as well.
