[Bug 47048] New: Logitech webcam does not show picture, only grey
https://bugs.winehq.org/show_bug.cgi?id=47048 Bug ID: 47048 Summary: Logitech webcam does not show picture, only grey Product: Wine Version: 4.6 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: beniwtv(a)relamp.tk Distribution: --- Created attachment 64216 --> https://bugs.winehq.org/attachment.cgi?id=64216 Log when running webcam application with qcap debugging enabled I have a Logitech C920 HD Pro Webcam that works flawlessly on v4l2 in any Linux application. However, under Wine as long as I can remember this never worked in the 4.x series or 3.21 (didn't test older) - only showing a grey picture (even though the applications detect it). Right now I am testing with Star Citizen's FOIP and "Portable Webcam" application, both which seem to use qcap/DirectShow for this. I saw qcap being updated to v4l2 in 4.6 (even tried 4.7), but I still get a grey picture only. Portable Webcam can be obtained from SourceForge: https://sourceforge.net/projects/portablewebcam/ I have attached a log with qcap debugging made with today's wine GIT version (let me know if I can/should further increase wine debugging channels) What's also to note (but probably not related to the error) is that Wine seems to prefer the video1 device (a metadata/advanced settings device related to the other one) and not video0, so I have to rm that device node.

I have a Logitech C920 HD Pro Webcam that works flawlessly on v4l2 in any Linux application. However, under Wine as long as I can remember this never worked in the 4.x series or 3.21 (didn't test older) - only showing a grey picture (even though the applications detect it).
It sounds to me like you're looking for any app that can capture video in Wine. There are some that do. Try the Windows version of VLC for example (Media -> Open Capture Device -> Play).
What's also to note (but probably not related to the error) is that Wine seems to prefer the video1 device (a metadata/advanced settings device related to the other one) and not video0, so I have to rm that device node.
That /dev/video0 vs video1 bug was fixed by several commits between 20 and 23 April 2019, just a few days after your bug report. Please retest with a recent version of Wine, and if you still get it, report which version. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

We're actually looking to get FOIP in Star Citizen working :) Some apps may use a different API I guess for capturing, indeed Star Citizen seems to use the same as "Portable Webcam" (hence the example).
