Tizen Developers

I want to play an encrypted media file from my local storage like pendrive. I am using crypto JS for decrypting, but I want to decrypt it byte by byte without overloading the ram.

I have 1.5 GB of ram in a tv device. It has Tizen 5.5 and I am able to play encrypted media that is 3 minutes long using Media Source Extensions.

I am seeking help regarding the data reading and decryption via the filesystem itself, as loading the entire blob has issues.

I also want to know if a media that is 1hour long but uncrypted is played inside the web app but when I process the encrypted file, the app crashes.

Thanks
