Re: RPi Cam Web Interface

Hi, I am unable to do video capture by sending a 'ca 1' to FIFO. I remember I could do this, when I last used a few months back. I am not starting the scheduler (php schedule.php) 1) I am only starting raspimjpeg: sudo su -c raspimjpeg www-data I see that the last two lines in stdout are: MJPEG stre...

Re: RPi Cam Web Interface

Two bugs with the rpi cam web interface. I am using camera rev 2.1 on a pi0, commit 78b5. Am facing a few issues. 1) If scene is not very bright, video capture always gets much darker. For the same scene, still image looks fine. But video, is very dark. This happens with exposure modes off, auto, ni...

Re: RPi Cam Web Interface

So, definitely there is something not right with motion detection. In fact, so far there is only one set up in which everything works: A raspberry pi 1 with stretch installed, kernel version "Linux picam 4.14.62+ #1134". The rpi cam web interface code is on an older commit - commit 7071b617311c52f6...

Re: RPi Cam Web Interface

As a process of elimination, you might want to try turning motion detection off if you haven't already. @Oldjake, The problem exists only when motion detection is on. I am quite sure something is wrong with motion detection. Even on the 'good' pi (rpi 2 model b), where there is no kernel crash, I s...

Re: RPi Cam Web Interface

Hi btidey,
Thanks. I think my power cables and adapters are good. Thick and bought from a reputed place that sells a lot of rpis. I will keep this in mind though.

So, it appears the latest code on jessie does work fine. Something not right at my end. So, a new pizero is the next step I guess.

Hello all,
Sorry for being away. Thanks for the comments. I will look at FLTK. One thing I wanted to mention is - I am not particular about using C++. I was mentioning that, C++ is all I have worked with. However, I am happy to learn anything except java :).

Thanks
