As for the alignment issues, you'll see that the first line of each block *is*
decoded correctly, only the next 15 lines per block have wrong alignment on the
left border. The colors in the rest of the image are correct. So we may actually
not have any stride issues, but just a missing setting in libjpeg or something.

Now, if we look at line 488 of gstjpegdec.c, we do for (i = 0; i < height; i +=
r_v * DCTSIZE) ... DCTSIZE is 8 and r_v = v_scale = 2, so this is indeed the
problem. We're just setting block offset, we're not setting stride.
