Browse Source

requires the MDP for further processing.

Also fix the fourcc (it was a fivecc :-) )

* .. _V4L2-PIX-FMT-MT21C:
- ``V4L2_PIX_FMT_MT21C``
- 'MT21C'
- 'MT21'
- Compressed two-planar YVU420 format used by Mediatek MT8173.
The compression is lossless.
It is an opaque intermediate format, and MDP HW could convert
V4L2_PIX_FMT_MT21C to V4L2_PIX_FMT_NV12M,
V4L2_PIX_FMT_YUV420M and V4L2_PIX_FMT_YVU420.
The compression is lossless.
It is an opaque intermediate format and the MDP hardware must be
used to convert ``V4L2_PIX_FMT_MT21C`` to ``V4L2_PIX_FMT_NV12M``,
``V4L2_PIX_FMT_YUV420M`` or ``V4L2_PIX_FMT_YVU420``.
