USB Camera problem

[championc]

Hi all,

I hope that someone can assist. I am using a CCTV application called MotionEye which uses Motion , which is installed on a Linux Mint installation using a Local USB V4L2 camera. While this USB camera works perfectly within Cheese, it won't work with Motion.

With version 3.2.12, I got the following errors repeatedly over and over "[1] [WRN] [VID] v4l2_select_input: Device doesn't support VIDIOC_G_STD".

I downloaded and installed Motion 4.0.1 (I used Xenial_Motion version - is this correct for Mint 18 ?). It seemed to install OK, but I now get the errors [1:ml1] [ERR] [ALL] my_error_exit: Quantization table 0x00 was not defined [1:ml1] [CRT] [VID] mjpegtoyuv420p: Corrupt image ... continue

[Mr-Dave]

Can you post the full log at the NTC(6) log level to gist and maybe we can get a better sense of what is happening.

[championc]

Is there a command line switch to set this ? If so, what is is or otherwise, how do I do this ?

[Mr-Dave]

The log level can be specified using this or within the configuration file here. The NTC level is usually the default. Unfortunately, you are caught between two applications on how to do this within Motioneye. We don't use Motioneye and only use the Motion application standalone so our responses will be framed in the context of Motion rather than MotionEye.

[championc]

The log level is already set to 6 (in motion.conf)

[tosiara]

Your motion logs into syslog. Can you please extract and provide full log from startup to see camera details?

[Mr-Dave]

It would probably be best to specify a different file for logging instead of the sys log. Do this via the log file option. The important parts are all the things before the error messages start being reported.

[championc]

Sorry. I set the level and other settings in the wrong config file. Sorted now - see below

Can you try to plug this camera into usb 2.0 port?

[championc]

Unfortunately it IS connected to a 2.0 port already

[Mr-Dave]

Thanks for the log, it helps identify the issue. The log reports a Pixart variant of JPG (PJPG) as the only format for the camera. Motion uses a external library to decode the pictures into a format that we can process. The error being reported is from that external library not being able to decode the PJPG image. Web searches of that format did not provide many results at all so I am guessing it is a really old camera. Generally, I think the best option is to try a different camera. The only other option would be to build the Motion code from source and try specifying different JPG libraries hoping one of them can decode the PJPG.

[championc]

Thanks for the replies. The webcam isn't too old I would have thought. I had another which is very old and which I could never get to work in Windows since it never found a compatible driver - but both webcams worked in Cheese.

Unfortunately, I'm already pushing the boundaries of my knowledge and re-compiling something by selecting different libraries is well beyond my skill level.

Thanks anyway.

[tosiara]

Can you capture a sample frame and share it? Clone v4l benchmark repo:

git clone https://github.com/tosiara/v4l-capture-bench

Run:

cd v4l-capture-bench
make
./v4l-capture -c 1 -o 1> test.jpg

Upload somewhere test.jpg file for analysis

[tosiara]

I also recommend to zip the file before attaching here or uploading. Just to prevent any changes or corruptions

[Mr-Dave]

I am closing this issue that is particular to this camera format and have opened issue #279 that addresses the larger issue of cameras with unusual pixel formats. That issue will be tracking whether Motion can use the same libraries that Cheese uses in order to process images from the camera.
