  wrong chroma buffer offset after decode

  Posted by Sanjay Soni on November 9, 2011 at 10:58 am

  Hi,
  I am using ffmpeg to decoder my H264 stream.
  My problem is that in the output yuv – I am seeing that
  data[1] != data[0] + (linesize[0] * height)

  rather data[1] is data[0] + (linesize[0] * height) + some more offset.

  Can somebody tell, why ffmpeg allocates y, u and v pointers separately and not give offset from a big buffer ?

  Perhaps your video stream includes VBI?
