SR300 driver installation issue, distorted/flickering depth image and no infrared image

Hi,

I am trying to install the drivers for the SR300, but when I run ./bin/cpp-capture, then the depth image flickers and is distorted. There is also no infrared image visible, see image below (it's a paper box on a sheet of paper):

These are the steps and some results:
git clone https://github.com/IntelRealSense/librealsense.git

I followed the instructions:
https://github.com/IntelRealSense/librealsense/blob/master/doc/installation.md
There I have chosen step:

(OR) Kernel in 14.04.xx

(I also tried section "Updated 4.4 Stable Kernel" in a different attempt, after restoring my system from a diskimage before attempting to install the realsense drivers)

Some Interesting outputs, when running ./scripts/patch-uvcvideo-ubuntu-mainline.sh :

gpgv: Signature made Fri 12 Aug 2016 07:41:55 AM EDT using RSA key ID CBEECEA3
gpgv: Can't check signature: public key not found

The driver uvcvideo seems to register fine:

It seems the automatic uvcvideo patching has failed during ./scripts/patch-uvcvideo-ubuntu-mainline.sh. Please give it another try (fetch another copy of librealsense and re-run patch-uvcvideo-ubuntu-mainline.sh there). The patch should apply without any issues.
However, you can always take the patch as a reference, manually modify the relevant source files, compile and replace uvcvideo.ko. That's exactly what patch-uvcvideo-ubuntu-mainline.sh supposed to do but it can give you a better understanding of where the problem is.

Hi Sergey,

Thanks. I will rerun the patch and also look at the patch itself. I hope that tells me something.

I'm having the same problem with ./scripts/patch-uvcvideo-ubuntu-mainline.sh. I haven't fixed the Hunk #1 FAILED at 621. issue yet, but I believe I've fixed gpgv: Can't check signature: public key not found with:

gpg --keyserver keyserver.ubuntu.com --recv-keys CBEECEA3
gpg --no-default-keyring -a --export CBEECEA3 | gpg --no-default-keyring --keyring ~/.gnupg/trustedkeys.gpg --import -

The patch is incompatible with at least Linux 4.4.0-36 and 4.4.0-34.

The patch is trying to add definitions for V4L2_PIX_FMT_Y8I, V4L2_PIX_FMT_Y12I, and V4L2_PIX_FMT_Z16 on lines 174, 175, and 176. However, these definitions already exist in my videodev2.h. /usr/src/linux-headers-4.4.0-36/include/uapi/linux/videodev2.h and /usr/src/linux-headers-4.4.0-34/include/uapi/linux/videodev2.h contain:

#define V4L2_PIX_FMT_JPGL   v4l2_fourcc('J', 'P', 'G', 'L') /* JPEG-Lite */
#define V4L2_PIX_FMT_SE401      v4l2_fourcc('S', '4', '0', '1') /* se401 janggu compressed rgb */
#define V4L2_PIX_FMT_S5C_UYVY_JPG v4l2_fourcc('S', '5', 'C', 'I') /* S5C73M3 interleaved UYVY/JPEG */
#define V4L2_PIX_FMT_Y8I      v4l2_fourcc('Y', '8', 'I', ' ') /* Greyscale 8-bit L/R interleaved */
#define V4L2_PIX_FMT_Y12I     v4l2_fourcc('Y', '1', '2', 'I') /* Greyscale 12-bit L/R interleaved */
#define V4L2_PIX_FMT_Z16      v4l2_fourcc('Z', '1', '6', ' ') /* Depth data 16-bit */

/* SDR formats - used only for Software Defined Radio devices */
#define V4L2_SDR_FMT_CU8          v4l2_fourcc('C', 'U', '0', '8') /* IQ u8 */

So to fix the issue, replace lines 170-176 of scripts/realsense-camera-formats.patch with:

@@ -624,6 +624,19 @@ struct v4l2_pix_format {
 #define V4L2_PIX_FMT_Y8I      v4l2_fourcc('Y', '8', 'I', ' ') /* Greyscale 8-bit L/R interleaved */
 #define V4L2_PIX_FMT_Y12I     v4l2_fourcc('Y', '1', '2', 'I') /* Greyscale 12-bit L/R interleaved */
 #define V4L2_PIX_FMT_Z16      v4l2_fourcc('Z', '1', '6', ' ') /* Depth data 16-bit */```

Matt and I were able to get the SR300 camera driver to install correctly.

hello,
I encountered the same problem as yours, flickering depth image and no infrared image.I followed the the same instructions: https://github.com/IntelRealSense/librealsense/blob/master/doc/installation.md
my linux Kernel is:
Linux hai-ubuntu 4.4.0-040400-generic #201601101930 SMP Mon Jan 11 00:32:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Operating System & Version: Ubuntu 14.04.5 LTS

I have read the above solutions, but I still can't fix my issue.

How can I handle my problem?
Thank you very much.

[changhai0551]

I have installed the driver correctly.

[changhai0551]

Just rerun the ./scripts/install_dependencies-4.4.sh and ./scripts/patch-uvcvideo-4.4.sh v4.4-wily and follow the next steps.

[changhai0551]

Hi, Uliv
I encountered the same problem as yours, flickering depth image and no infrared image.
Also, sudo dmesg | tail -n 50: outputs
usbcore: registered new interface driver uvcvideo
could you tell me how you fix your problem?
Thanks you very much.
