Binary data and image converting to string

Question

I have key ,value pair(key="photo" and value="image.png") in terms of binary. I want to convert to dict

imag_bytes=b'{"photo": matrix data}'

How can I convert into dict for accessing matrix data

Data=photo["photo"] What's to matrix data.

Suggest me.

You are aware that you question is not really intelligible, aren't you? It is not just the English part. Not just what should be code: there is no way one can meaningfully help you with what you've posted here. — jsbueno, Jun 07 '22 at 17:09
Please provide enough code so others can better understand or reproduce the problem. — Community, Jun 07 '22 at 17:32
Ask someone around you to formulate your question in English. — , Jun 07 '22 at 19:59
again, do not use json, do not use base64. send the file itself, in binary. https://stackoverflow.com/questions/72515981/poco-client-sending-image-using-c — Christoph Rackwitz, Jun 07 '22 at 21:45
this should never have been tagged as `OpenCV`. it's a plain python question. — Christoph Rackwitz, Jun 08 '22 at 11:46
yes after getting data i want to show using imshow using opencv — REDDY, Jun 09 '22 at 03:59

You can convert the image to a base64 string. This is a common way of sending binary data over text based protocols.

Yes, you're correct In my case I send data as binary( key and val pair) and I want to aceess the value based on key. – REDDY Jun 07 '22 at 17:17
**do not** use base64. that's an insane suggestion. image files can be sent as is, in binary, without base64, without json, without any shenanigans. – Christoph Rackwitz Jun 07 '22 at 21:45
if you mind give some examples – REDDY Jun 08 '22 at 09:52

@ChristophRackwitz thanks, But that is sending one image but I want to send live stream data. – REDDY Jun 10 '22 at 02:55
over a HTTP POST request? your question doesn't do any streaming. blowing data up by using json and base64 encodings doesn't cause live streaming either. – Christoph Rackwitz Jun 10 '22 at 10:58
