Re: MJPG stream is not working with kernel 3.18

Well, you can always apply the patch manually, it should be as easy as (raspberry) pie.

Re: Webcam to capture videos on Raspberry Pi

You can install qv4l2 instead of guvcview , because it is not working with kernel 3.18 (3.16+) due to a bug in guvcview . There shouldn't be a problem with motion if you use YUYV mode (or other mode than MJPG). Another program is mjpg_streamer that works either in MJPG mode or YUYV mode, however you...

Re: MJPG stream is not working with kernel 3.18

Mjpg-streamer uses much more CPU in YUYV mode than in MJPG mode, e.g. 0-1% CPU vs. 35-40% CPU for "-r 960x720" and "-f 2".

Backup is not needed, because changing to a different kernel and firmware is pretty easy with sudo rpi-update "commit hash" so I went back to the latest kernel 3.12 sudo rpi-update 6413da9f74871b239c5bd27d7edf90a8afeab363 A...

Re: Motion raspberry pi B+

Well, you have still kernel 3.12, so it seems to be a different issue. Is your webcam working with other software, such as guvcview or mjpg_streamer? Which kernel messages can you see after attaching your webcam and then after running motion?

Code: Select all

$ dmesg

Re: Motion raspberry pi B+

Do you have same version of kernel and firmware on both Raspberry Pi?

Code: Select all

$ uname -a

Code: Select all

$ vcgencmd version
It might be the same issue as my problem http://www.raspberrypi.org/forums/viewt ... 28&t=97983

Re: MJPG stream is not working with kernel 3.18

No, I can't see any new kernel message after running either motion or mjpg_streamer . When I reconnect USB webcam kernel messages are as follows: $ dmesg [ 557.172905] usb 1-1.3.2: new high-speed USB device number 9 using dwc_otg [ 557.485111] usb 1-1.3.2: New USB device found, idVendor=046d, idProd...

MJPG stream is not working with kernel 3.18

After upgrading to a new kernel 3.18 MJPG stream is not working with my USB webcam Logitech C270 (I have also tried it with Logitech C160, but it did not work either). I have tried to use several programs - guvcview , mjpg_streamer and motion - but I can see only white, grey or black screen depends ...
