Hi brajan1,

Thanks for your message and welcome to the PowerVR Developer Forum!

The message:

`Warning: Failed to find a valid platform extension for window system win32. Falling back to eglGetDisplay for playback of call 1 (eglGetPlatformDisplayEXT)`

could mean you are trying to play the recording on a device which is not 100% compatible with the features present in the recording. Sometimes PVRCarbon can emulate some of those features, sometimes it cannot.

Are you trying to play the PVRCarbon recording taken from a Yocto Linux device on a Windows machine? Please while on PVRCarbon GUI, select the device where the recording is being played back:

If some users can play a recording back, please:

- Check with them what setup do they have with PVRCarbon
- What device are they playing the recording on.
- If they are using a device different from a local Windows machine, verify how PVRCarbon is connecting to that device.

Best regards,  
Alejandro
