Re: Stereoscopic camera capture - now implemented.

I still can't quite see why it doesn't work for you when you've increased max_preview_video_h, but I'll look instead at fixing the firmware than further hacks to userland. In the meantime, try increasing that value further as I'm fairly certain it is that that is going wrong. Increasing the initial...

Good point. I am indeed using a different camera board than you: the V1.3 5MPix camera board.

Hehe, ok, I'll stick to firmware and kernel versions from now on. :D uname -a gives me Linux rpicompute 4.4.14+ #895 Sun Jun 26 13:39:34 BST 2016 armv6l GNU/Linux and vcgencmd version gives me Jun 27 2016 17:25:36 Copyright (c) 2012 Broadcom version 1e7b8e2c9a7319f7b22869f1334c66e2cfc99f4a (clean) (...

Re: Stereoscopic camera capture - now implemented.

I am currently running version 1.3.12 of raspivid. Since it seems I am not doing something wrong with the program calls I will try to update the firmware via rpi-update and check if I can get your 640x960 example to work, too. :D I'll try to update the userland raspivid source code according to your...

Re: Stereoscopic camera capture - now implemented.

Update: I added start_debug=1 to the /boot/config.txt, restarted the CM and tried to record a video with the following command raspivid -3d tb -w 640 -h 960 -o tbfull.h264 The result of this is the expected 26 byte (correction: not 29 as stated previously) output file. The call of sudo vcdbg log ass...

Re: Stereoscopic camera capture - now implemented.

Thanks for the quick and detailed reply! I will follow your instructions regarding the debug output and post my results. Also good to know that the size restriction should only apply to the image width. Strange thing though that I was unable to record a full height top-bottom video in 640x960. That ...

Re: Stereoscopic camera capture - now implemented.

Hi everybody I'm searching for help in this thread since I have a hard time getting some features of the stereoscopic mode to work properly. I am testing the stereoscopic camera features on the Compute Module currently using raspivid. The problem arises if I try to record a Top-Bottom video in half-...
