[libcamera-devel] libcamera Android Enhancements

[Nicholas Roth]

All,

Please find a summary below of the latest changes, along with a few discussion points.

Changes:
* Reorder commits so that commits required to use libcamera with Android are before the makefiles and the ov8858 addition is after
* Change FrameDurationLimits commit to compute frame duration limits based on sensor VBLANK with minimum possible HBLANK on every video mode change, tested on Linux with qcam, tested on Android with "Device Info HW" app -> Camera (HAL does not produce pictures yet with rkisp1)

Additional discussion:
* Kernel patch for ov8858 driver submitted to linux-media mailing list as [PATCH] media: i2c: ov8858 Add driver for ov8858
* If people don't like a build-time flag to disable IPA isolation, would the community be open to checking for an Android filesystem with presence of /vendor, /system, etc. and disabling isolation if found? I personally like this less than the proposed build flag but would be open to it.
