[PATCH v2 0/8] Signal metadataAvailable and Android partial result

[Harvey Yang]

Hi folks,

This series of patches adds a new signal metadataAvailable in
libcamera::Camera, and supports partial result in Android adapter.

Although Android allows a partial result to contain both buffers and
metadata, we probably don't need such a feature. Splitting them into
different partial results should fit both MediaTek's and Intel's
requirements.

This patch passed gitlab pipeline:
https://gitlab.freedesktop.org/chenghaoyang/libcamera/-/pipelines/1317276

There are still some discussion of the new signal in the previous patch,
with Jacopo. I'll update the patch when we reach agreement.

I understand that the last patch is a bit large, while I don't know how
to split that furthermore. Let me know if there are some pieces that can
be standalone patches.

BR,
Harvey
