Package: cheese Version: 3.20.2-1 Severity: important Dear Maintainer,
After I open Cheese, the video appears for a brief instant (perhaps only a single frame or so) and then immediately goes back to a black screen that says "There was an error playing video from the webcam" I get the following error message in the standard error stream: (cheese:10630): cheese-WARNING **: Internal data flow error.: gstbasesrc.c(2948): gst_base_src_loop (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin28/GstV4l2Src:v4l2src1: streaming task paused, reason not-negotiated (-4) One workaround I found was running cheese under "sudo". That causes the video to appear just fine and the "internal dataflow error" message goes away. However, I suspect that this is a bug in cheese and not just me having the wrong permissions set up. Firstly, there is a brief glimpse of video when I run cheese without sudo, so it appears to have permissions to bet to the video in the first place. Secondly, in other applications I tested (guvcview and Skype) the webcam seems to work just fine, without requiring me to use sudo. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.5.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=pt_BR.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages cheese depends on: ii cheese-common 3.20.2-1 ii gnome-video-effects 0.4.1-3 ii libc6 2.22-9 ii libcanberra-gtk3-0 0.30-3 ii libcheese-gtk25 3.20.2-1 ii libcheese8 3.20.2-1 ii libclutter-1.0-0 1.26.0-2 ii libclutter-gtk-1.0-0 1.8.0-1 ii libgdk-pixbuf2.0-0 2.34.0-1 ii libglib2.0-0 2.48.1-1 ii libgnome-desktop-3-12 3.20.2-1 ii libgstreamer1.0-0 1.8.1-1 ii libgtk-3-0 3.20.4-1 Versions of packages cheese recommends: ii gnome-icon-theme 3.12.0-1 ii gvfs 1.28.2-1 ii hicolor-icon-theme 0.13-1 ii nautilus-sendto 3.8.3-1 ii yelp 3.20.1-1 Versions of packages cheese suggests: pn gnome-video-effects-frei0r <none> -- no debconf information
