[FFmpeg-devel] [PATCH] IFF PBM: Add a pad byte if image width is odd

It seems that IFF PBM uses padding for each line of pixel data. The
current decoder does not do that, yet for example Multishow does. The
fix is simply

-            buf += avctx->width;
+            buf += avctx->width + (avctx->width % 2); // padding if odd

but I attached it as a patch, too. It does not affect the regression tests.

There's a sample at http://cs.helsinki.fi/u/ahnurmi/iff-pbm-with-odd-width.bbm
