Hi @Andreas Thank you for the reply. so the issue I had highlighted here below was seen with the version 13.04.006 of CVB. > [@keerthitheja](#): > > So, I tried to dump the crash using exception, the program mostly crashes at Stream-\>Wait(). The exception it gives me always is the **` composite is not an image`**. This exception mostly occurs only for the NIR stream. I am having difficulty in setting the pixel format for each stream individually using CVB++. Setting the pixel format is via the CVB device nodemap and with this, I can either set it to RGB8 or Mono before I start the streams. Is it possible to set the pixel format for each stream individually ? For more understanding of my problem, please refer to the below thread [https://forum.commonvisionblox.com/t/modifying-individual-pixelformat-settings-for-dual-streams-of-a-multispectral-camera/1696?u=keerthitheja](https://forum.commonvisionblox.com/t/modifying-individual-pixelformat-settings-for-dual-streams-of-a-multispectral-camera/1696) --- _[View the full topic](https://forum.commonvisionblox.com/t/is-running-data-streams-of-a-multispectral-camera-in-threads-thread-safe/1741)._
