Hi Sergey

Can you share the result of fluster test for h264 and vp8 decoder?

Thanks
Jackson

> Hello!

> This is the implementation of the Chips&Media "CODA988" video codec
> support within v4l2 driver for coda. Support for the following codecs was
> implemented:
>  * h264:   decoder & encoder
>  * h263:   decoder & encoder
>  * mpeg4:  decoder & encoder
>  * vp8dec: decoder
> 
> Support for the following formates was implemented:
>  * yuv420p(I420)
>  * yvu420p(YV12)
>  * NV12
>  * NV21
> 
> Also the following features and fixes were implemented for coda988:
>  * special config for mem_ctrl
>  * special config for encoder header (sps and pps)
>  * special set profile_idc
>  * special set RC config
>  * special set QP
>  * special set slice mode
>  * special set Motion Extimation (ME)
>  * v4l2_ctrl for h264 profile
>  * v4l2_ctrl for h264 level
>  * v4l2_ctrl for h.264 RC mode
>  * v4l2_ctrl for h.264 skipFrame
>  * v4l2_ctrl for h.264 i-frame min/max qp
>  * v4l2_ctrl for h.264 p-frame min/max qp
>  * v4l2_ctrl for h.264 entropy mode
>  * v4l2_ctrl for h.264 8x8transform
>  * v4l2_ctrl for h.264 i-frame period
>  * v4l2_ctrl for h.264 Access Unit Delimiter(AUD)
>  * v4l2_ctrl for h.264 me x/y search range
>  * v4l2_ctrl for h.264 intra refresh period
>  * v4l2_ctrl for h.263 intra/inter qp
>  * v4l2_ctrl for h.263 min/max qp
>  * v4l2_ctrl for mpeg4 min/max qp
> 
> During adding support for "CODA988" we also did some extra work related to
> refactoring and improvement of generic part of C&M coda
> driver:
>  * Improve error checking for probe, irq-handle and etc.
>  * Update work with resets
>  * Replace hard_irq by threaded_irq
>  * Remove double setting of stop flag
>  * Improve some prints
>  * Fix loglevel to avoid performance failure
>  * Fix support of MPEG4 levels
>  * Fix setting gamma for h264enc
>  * Update default velues of QP for mpeg4 I/P
>  * Other minor fixes

> Sergey Khimich (18):
>   media: coda: Add print if irq isn't present
>   media: coda: Use get_array to work use multiple reset
>   dt-bindings: media: coda: Fix resets count
>   media: coda: Add check result after reset
>   media: coda: using threaded_irq for 0 (bit) interrupt
>   media: coda: Add reset device before getting interrupt
>   media: coda: Add fake IRQ check
>   media: coda: Add log to finish_encode if buffer is too small
>   media: coda: Fix max h.264 level for CODA_DX6
>   media: coda: Remove double setting of stop flag
>   media: coda: Print size of encoded buff in other place
>   media: coda: Fix loglevel for seq mismatch print
>   media: coda: Fix support for all mpeg4 levels
>   media: coda: Fix handling wrong format in coda_try_fmt
>   media: coda: Use v4l2_ctrl to set gamma for h264enc
>   media: coda: Update default velues of QP for mpeg4 I/P
>   media: coda: Use preferred usleep_range than udelay
>   media: coda: add support coda988 enc and dec
