[FFmpeg-devel] [PATCH] check for overflow in wmv decoding (roundup issue 1670)

[Daniel Kang]

As part of a Google Code-In task, I have written a patch to fix the bug
in roundup issue 1670. The issue occurs because there is a sanity check
on s->avctx->extradata_size, but not on s->avctx->extradata_size*8,
which overflows in some cases. My patch updates the sanity check.
Are there any comments?
