[libcamera-devel] [PATCH 0/8] Use two imgus in ipu3 pipeline handler

[Harvey Yang]

Hello everyone,

This is the first draft of patches to use two imgus in ipu3 pipeline
handler, mostly to better support StillCapture, which was handled as
video snapshot.

There's a TODO to tackle the delay one frame issue in the ipu3 HW/FW
design. Patches will be updated when we have a clear solution.

Please take a loop and give me your thoughts. Thanks!

BR,
Harvey
