[Bug 1295247] Re: Cheese says "There was an error playing video from webcam"

 

I have the same problem using a Realtek cam on a 2015 Razer Blade 14".
When I start cheese, I get some half video for a couple seconds then it
dies with:

libv4l2: error got 4 consecutive frame decode errors, last error: v4l-
convert: libjpeg error: End Of Image

(cheese:14656): cheese-WARNING **: Internal data flow error.: gstbasesrc.c(2865): gst_base_src_loop (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin17/GstV4l2Src:video_source:
streaming task paused, reason error (-5)

The camera is:

Bus 001 Device 006: ID 0bda:579f Realtek Semiconductor Corp.

I have more camera info here if someone is interested:

The camera works perfectly with luvcview. The camera fails with cheese
in default settings, but sorta works if I go into preferences and choose
1280x720 resolution for images and video and restart cheese. I still get
a horizonal line in the video near the bottom though. The camera fails
with the gumwrapper example in Firefox.

The camera looks scrambled on the same example in chromium, very similar
to if I had chosen 640x480 in cheese as the camera resolution. Using
ubuntu 14.04.3. Cheese fails with default kernel as well as 4.0 vivid
kernel.
