Nah it's just normal question like any other in the open-source world, if I'm trying to highlight something then it would be my limited knowledge of Android :P

Thanks for the reply, I'm unfamilar with Android Camera(2) API. When it's not RAW mode, is the data returned from the camera a JPEG codestream or RGB? Maybe I can prevent a second color transform by re-using JPEG's YCbCr stuff to feed the encoder of some format idk

To be honest if I record two videos with different content and their file size varies greatly but the quality doesn't change much then I don't think my device's Android API is compromised, after all the purpose of lossy compression is to retain as much quality as possible using the smallest amount of space possible within the time constraint. And you can't test whatever the app or your OS has been compromised or screwed up by testing the same settings on different subject (videos) and expecting the...

What exactly is the key you're mentioning? I don't see the Checkey app displaying any field named 'Key'. Based on your description I think you're referring to hashes? The hashes are calculated for the signed APK so surely they will not be the same for both Mark's signed build and F-Droid's signed build. You don't know what you are talking about Here is the primary source from which I based my statements from: https://f-droid.org/docs/Reproducible_Builds/#reproducible-signatures

F-Droid was doing reproducible builds where the signing key would be potentially the same because the data built by F-Droid turns out to be exactly the same as the data you the developer signed with open source It's not the key that should be the same, the idea is that executables built by F-Droid and the executables built by the developers should be the same after the signature of the developer's build get copied into F-Droid's build. The secret key is like a secret password held by someone to proves...

I'm trying to add JPEG XL encoding into OpenCamera, from what I understand, the output of the camera, if not in RAW mode, is compressed using JPEG with the quality specified by API user. When the saveSingleImageNow method compress the bitmap using the bitmap.compress method, is the resulting image actually the 2nd generation?
