[BUG] Corrupt streaming display for some frames

[MikeNice-IB]

Describe the bug
When scanning fingerprints , some random frames are partially obscured by a dark gray bar - generally when the image changes during scan, not when showing a constant image over and over.

To Reproduce
Steps to reproduce the behavior:

1. Perform any fingerprint scan and observe the streaming image during the scan.

Expected behavior
Streaming display should show just the fingerprint images. The same streaming images show no problem on a web browser reading the stream.

Screenshots

Environment (please complete the following information):
Edition Windows 10 Pro
Version 22H2
OS build 19045.5131
Experience Windows Feature Experience Pack 1000.19060.1000.0

Attach logs

Additional context

Streaming located at registration-client/registration/registration-client/src/main/java/io/mosip/registration/controller/device/Streamer.java appears to add an extra byte to each image: line 166 allocates 1 byte more than the embedded image length as obtained in the content-length of the stream.

Dear Mike,
It would be helpful if you could share more information for analysis, including the Registration Client versions, SBI details (vendor and version), and device details (make and model) etc..

@n-chandrasekhar I am not sure if we have these devices with us., can you please check with team once..

I don't remember we observed this with mockMDS, can you please confirm

Looks like it is related to data what device is capturing and sending to regclient for display/preview

I don't observe this with the mockMDS. I was going to create a custom MockMDS that sends multiple image frames to illustrate the problem. I was able to get MockMDS to build but cannot get the RegClient to recognize the new custom mockMDS device - likely a key problem.

The problem is most visible as the image changes from frame to frame.
