Subject: [PATCH 00/25] Enable H.264/H.265 encoder support and fixes in
common code
Hi All,
This patch series adds support for H.264 and H.265 encoder in iris
driver and includes a few fixes and cleanup in the common code that were
identified during encoder bring-up process.
The changes include:
- Enabling support for H.264 and H.265 encoding.
- Fixes and improvements in shared componenets used by both encoder and
decoder paths.
- Ensuring compatibility and stability with the existing decoder flow.
All patches have been tested with v4l2-compliance, v4l2-ctl and
Gstreamer on SM8250 and SM8550 for encoder, at the same time ensured
that the existing decoder functionality remains uneffected.
The result of v4l2-compliance on SM8550:
v4l2-compliance 1.29.0-5270, 64 bits, 64-bit time_t
v4l2-compliance SHA: dc947661089e 2024-11-11 10:25:38
