[vdr] VDR - xine - CoreAVC

OK, I spent a bit of time looking at this today as there doesn't seem
to be much movement on FFMPEG and H264 at the moment.

I have managed to get xine to now detect the H264 video size prior to
starting up the CoreAVC decoder and set the size within the
initialisation function: -

      memset(&bih, 0x00, sizeof(bih));
      bih.biWidth = sps.width;
      bih.biHeight = sps.height;
      bih.biPlanes = 1;
      bih.biBitCount = 24;
      bih.biCompression = 0x34363248; //31435641; //AVC1
      bih.biSizeImage = 0;
      bih.biXPelsPerMeter=10000;
      bih.biYPelsPerMeter=10000;
      bih.biClrUsed=0;
      bih.biClrImportant=0;
      bih.biSize = sizeof(bih);
      buf->content = malloc(sizeof(bih));

It detects BBC HD as the right video size, i.e. 1440 x 1080 - however
this now results in a squased image on the display with black bars
down the left and right sides. Any idea how you tell CoreAVC what the
video size is and to scale it to the size that xine is using? It
detects other video sizes such as 1920x1088 and displays them all
correctly on the screen so I know that we are now very close!

Once I get this bit right, I'll release a patch to xine's
demux_mpeg_pes.c that will properly detect the source video size prior
to starting CoreAVC.

Thanks for any help.
