Known issues in this version

  • If you change the video signal format for the video source connected to the ClearCaster from YUV to RGB without changing the frame size, the ClearCaster may stop responding. This occurs because the memory that the ClearCaster allocates to store the YUV format isn't sufficient when switching to RGB. If you change the video signal from YUV to RGB, also change the frame size to avoid this issue. This issue will be fixed in a future software update.

  • Wowza ClearCaster is the first release of the software.
