Hi all, I'm new to using the libavcodec library and am currently running into some issues trying to decode a M-JPEG stream that I collect from a webcam. I check the avContext->pix_fmt both before and after I call
avcodec_decode_video2(avContext, decPict, &gotPic, &avpkt) to determine what the pixel format is before/after decoding. Prior to decoding pix_fmt = -1 (i.e. PIX_FMT_NONE) and after decoding pix_fmt = 13 (i.e. PIX_FMT_YUVJ422P). 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.
