[PATCH v2 0/3] support of v4l2 encoder for STMicroelectronics SOC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



version 2:
- List of pixel formats supported by the encoder reduced to NV12 and NV21
- x86_64 compilation warnings corrected
- V4L2 compliance successfully passed with this version (see report below)
- All remarks about version 1 of hva-v4l2.c taken into account:
        - V4L2 mem2mem framework used 
	- V4L2 control framework used
	- allocator context initialized in the probe and cleaned up in the remove
	- start_streaming and stop_streaming ops added
	- colorspace, bytesperline and sizeimage fields initialized in TRY_FMT
	- better estimation of sizeimage for compressed formats
	- checks and debugging logs already covered by vb2 removed
	- some dev_err changed in dev_dbg
	- typos corrected

version 1:
- Initial submission.

Only one feature supported and tested:
- encode (NV12, NV21) to H.264 video format

The driver is mainly implemented across three files:
- hva-v4l2.c
- hva-h264.c
- hva-hw.c
hva-v4l2.c manages the V4L2 interface with the userland.
It calls the HW services that are implemented in hva-hw.c.
hva-h264.c manages specific part of H.264 codec.

Below is the v4l2-compliance report for the version 2 of the sti hva driver:
