I am not sure how to deal with YUVJ422P. My video player is currently
capable of working with YUV420P and I have to make it capable of
handling
YUVJ422P as well. So far I didn't find any information on how the
Y,U and V
arrays are organized in YUVJ422P or any other relevant information
about how
this format works (google did not help). I was hoping someone could
help me
determine how to either convert YUVJ422P to YUV420P or explain how
YUVJ422P
works or point me to some good resources. Your help is much
appreciated and
thanks in advance.
You can use the sws_scaler to convert it. However 422 is better
quality than 420.
It should be the same layout as 420 except the height of the chroma
channels are the same as the luma channel not half as with 420.
