[libcamera-devel] [PATCH v3 0/9] Virtual pipeline handler

[Harvey Yang]

Hi all,

This is the third version of POC patches of the virtual/fake pipeline
handler. Thanks to Kieran's comments, I split the patches and added a
base class MediaDeviceBase. Still need to work on the buffer allocation,
virtual config file, and virtual video for testing.

Please take a look and let me know if the design makes sense.

BR,
Harvey
