[HELP] video file "disguised" as image (png)

Hello, I've seen some sites that streams videos but if you download the part of the hls file and check its content you can see "‰PNG" if u try to use kodi to play that file it will fail as it will deal as an image, if you erase that "‰PNG" and save it as ts it will play with no problem
I tried to use the impustream with setMimeType to try to force to open a video but no success

Is there any settings im missing that could force to play it as video/ts?
Thanks in advance!

No source file or test is named. Start by reproducing the logged OpenStream and OpenWithCURL path with the supplied URL, then inspect how the inputstream handles the PNG signature, application/octet-stream MIME type, and requested video/ts interpretation. Done would mean the disguised video stream opens and plays correctly without manual byte removal.
