Re: Extracting RAW image from JPG

Straight DCRaw from Dave Coffin won't work on the "strange .jpg" which is the output of raspistill -r It will, but only on slightly older raws from the OV5647 (V1 camera module). It doesn't support IMX219 (V2 camera) nor flips changing the Bayer order. The OP has, in fact, a V2 camera. That's why I...

Re: Attaching flexcable

The flex flat cable is connected on one end to the Raspberry CSI port, via a sliding block connector; on the other end to the Camera Module board, via an almost identical (functionally identical) sliding block connector. So yes, you can replace the original flex flat cable with a longer one without ...

Re: Disabling ISP processing blocks

AWB is generally the culprit on weirder issues as it is expecting any lens shading effect to have already been removed before the statistics it works from are produced. If that isn't the case then it the colour compensations it produces are going to be skewed. A slight hesitation though as AWB only...

Re: Better Camera Replacement?

While we are on this topic: for nearly all my devices, I need a different lens vs. the stock one. No problem with Camera Module v1 since there are so many nice working clones out there, with CS or M12 mounts. I understand Camera Module v2 clones aren't going to happen because of embedded DRM. But I ...

Re: Youtube streaming video and sound

Actually "itsoffset" works for me (raspivid 1.3.11 + latest ffmpeg compiled from source). For example "-itsoffset 5.5 -async 1" correctly resyncs live audio and video which are otherwise out of sync by 5.5 seconds. But did you check it with streaming to YouTube? Yes, of course I did, otherwise I wo...

Re: Pi Camera v2 image quality question

This picture is too small to tell if it's blurry or not (and why). Could you post a full size image? In the meantime, I seem to notice a focus issue: distant objects are sharper than near subjects. I think the lens is focused at infinity by default; if your main usage consists in capturing scenes at...

Re: Disabling ISP processing blocks

Hello!

Excuse my noob question: is a "firmware update" like this automatically applied by Raspbian update (apt-get update + apt-get upgrade), or should we manually replace the old files with the new ones (in /boot etc.)?

Thanks A LOT for the new functionality by the way!!!
