Better Webcam Support
Summary
Currently many webcams do not work with Fedora out of the box even though Linux driver exist for them, the intent is to fix this.
Owner
- Name: Hans de Goede
Current status
- Targeted release: Fedora 10
- Last updated: (Jul 26 2008)
- Percentage of completion: 60%
Detailed Description
Webcams not working even though there are Linux drivers has 2 causes:
- The drivers are not in the mainline kernel
- Those drivers that are in the mainline kernel are often v4l2 while many applications will only work with v4l1. Even v4l2 apps often don't work with v4l2 webcam's as the webcams often have camspecific (compressed) pixelformats and most applications don't support all these,
1) Has been largely fixed by working together with gspca upstream to get gspcav2 cleaned up and merged, Linus has merged gspcav2 (through the v4l-dvb subsystem) for 2.6.27, this vastly improves the amount of supported webcams in 2.6.27. I'm currently working on getting the people behind the micromedia driver for the quite popular sonix sn9c20x based cams, to port their driver to a gspca subdriver and move the cam specific format decoding to userspace as was done with all the gspca decoding routines. The plan is to work together with the various upstreams to port any remaining standalone usb webcam drivers to gspca subdrivers, this is a process which will continue after F-10's release.
2) Has been fixed by creating a utility library which contains all the conversion stuff and v4l1 compatibility functions so that applications can easily be modified to work properly with v4l2 webcams, for more info on his library called libv4l, see: http://hansdegoede.livejournal.com/3636.html

Benefit to Fedora
Out of the box working hardware makes for happy end users and good reviews.
Scope
This may require temporarily carrying kernel patches if drivers are clearly moving upstream, but not there yet in time for release.
This requires packaging libv4l for v4l1 emulation and format conversion and making modifications to webcam using applications so that they use libv4l.
Test Plan
I currently have access to the following webcams (in random order):
| Webcam | USB ID | Bridge | Sensor | Status |
|---|---|---|---|---|
| Sweex WC001 | 0c45:6005 | sn9c101 | tas5110 | works |
| Sweex WC004 | 0c45:6011 | sn9c101 | ov6650 | works |
| Qware EasyCam | 0c45:6028 | sn9c102 | pas202 | works * |
| Intel Create and Share | 0733:0401 | spca501 | integrated | works |
| Creative Live! VISTA VF0420 | 041e:4064 | ov519 | OV7670 | works |
| Trust WB-1400T | 093a:2468 | pac207 | integrated | works |
| I.T. Works webcam | 093a:2460 | pac207 | integrated | works |
(*) works, but does not work well in low light conditions
User Experience
Out of the box working hardware.
Dependencies
None.
Contingency Plan
Don't ship the drivers / wrapper if they aren't ready.
Documentation
None atm.
Release Notes
None, except that if this is finished in time it would be good to make some PR with this.
