Subject: [PATCH] media: meson: add v4l2 m2m video decoder driver
|
|
|
|
Amlogic SoCs feature a powerful video decoder unit able to
|
|
decode many formats, with a performance of usually up to 4k60.
|
|
|
|
This is a driver for this IP that is based around the v4l2 m2m framework.
|
|
|
|
It features decoding for:
|
|
- MPEG 1
|
|
- MPEG 2
|
|
|
|
Supported SoCs are: GXBB (S905), GXL (S905X/W/D), GXM (S912)
|
|
|
|
There is also a hardware bitstream parser (ESPARSER) that is handled here.
|
|
