#20176 fixed ExtensionPack Webcam passthrough does not work with v4l2loopback on Linux host => fixed in SVN/next maintenance attilakinali
Description

While webcam passthrough works with hardware webcams into virtualbox and the guest OS, it does not work if the webcam is a v4l2loopback device. While the webcam becomes visible in the guest OS, it is not functional and will cause the application that opens it to either fail opening the device or keep looping while opening. This is independent of the guest OS.

The use case for this is for me passing video through OBS with all its video mixing and editing it offers on the host OS (which gives more flexibility than running it in the guest) and passing that video into the guest OS.

From discussions with the developer of v4l2loopback it seems like that virtualbox is using some lower level access to the device than v4l2loopback can offer. From that, and given that all other v4l2 applications are happy with the loopback device, I guess it should be pretty easy to get around and fix.

#20173 invalid port serie qui marche avec la version 5.2.44 et qui ne marche plus en version 6.0 ou 6.1 COLLAUDIN
Description

bonjour, je travaille avec un PC sous w10 (20H2) et une image virtuel en OS/2 WARP. quand je suis en version 5.2.44 la communication série entre OS2 et mon automate fonctionne très bien (chargement complet sans soucis temps de chargement environ 10 minutes). lorsque je migre en version 6, la communication ne marche plus (ne démarre plus du tout ou se bloque ou bout d'un moment). si je reviens en version 5, cela refonctionne. ce que je constate, c'est que la vitesse de transfert est beaucoup plus rapide comme si il ne tenait pas compte de la vitesse de transfert. pouvez-vous m'indiquer que faire pour que cela fonctionne en version 6. merci
