I have reflashed the latest system image (3.3) and installed the voxl-suite during the process. I also left my /data folder as is during the process (not deleting). I'm able to get the streamer to work for other cameras (hires, qvio-overlay, stereo etc), but when I try to run the tflite overlay I get the following error.
```
yocto:~$ voxl-streamer -c tflite-overlay -d 
Using configuration tflite-overlay
Enabling debug messages
Using configuration file /etc/modalai/voxl-streamer.conf
MPA interface chosen
Input pipe name /run/mpa/tflite/

Output stream rotation 0

No image overlay specified
Camera server Connected

```
I had this working before the latest updates, but checking out older versions of both the tflite and streamer services seem to throw the same errors.

Hi PawelJ, looks like there was a small bug in the tflite-server which made voxl-streamer expect an RGB output instead of grayscale. A fix will be available in version 0.1.1 which should be live on http://voxl-packages.modalai.com/ shortly.

Thanks for the quick reply. I've looked at the development in the tflite dev branch, and the changes in the patch that removes the `*3` scaling for RGB images fixes the size mismatch. However, the streamer seems to get the first frame then freeze when looking at the tflite-overlay. Is there any eta when the version of dev will be updated? I do not need the asset packages as I have your pipeline setup for installing the git branches.

Cheers

I tried the latest push to tflite master and it fixes the `size mismatch` error, but when I run the streamer I only get one frame and it never updates. This only happens when I try to connect to the `tflite-overlay`, the other streams work as expected. Are there any other packages that need to be updated?

Is anyone else experiencing this? I've tried reflashing the system and tested master and dev branches for tflite and the streamer, but I still get the stream frozen after one frame only for the tflite-overlay.

Hey PawelJ, voxl-streamer is unable to properly display the stream if the incoming framerate is too low. To fix this, edit the config file for voxl-tflite-server (lives here: /etc/modalai/voxl-tflite-server.conf) and change the skip_n_frames parameter to 0. This will increase the load on the CPU/GPU, but  will fix the "frozen frame" issue with voxl-streamer.

Thanks Matt, that did the trick :ok_hand:
