[FFmpeg-devel] [PATCH] mjpegb interlaced decoding fix

[Baptiste Coudurier]

Hi

For mjpegb_bottom.mov on mplayerhq/incoming

It seems that decoder currently decodes twice the first field, since
it uses buf and not buf_ptr which is incremented for second field:

 if (s->bottom_field && second_field_offs)
 {
      buf_ptr = buf + second_field_offs;
      second_field_offs = 0;
      goto read_header;
      }

"Start Of Scan offset
    The offset, in bytes, from the start of the field data to the start
of scan data."
