| | | | | | | | | | | | | | | | | | | | Istvan Sebok provided a sample where field pair -> two fields content was being misdetected by the existing logic. I added an additional test to check the input picture type as identified by our h.264 parser. Signed-off-by: Philip Langdale <philipl@overt.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| * vqavideo: return error if image size is not a multiple of block sizeMans Rullgard2012-05-03
| | | | | | | | | | | | | | | | | | | | | | The decoder assumes in various places that the image size is a multiple of the block size, and there is no obvious way to support odd sizes. Bailing out early if the header specifies a bad size avoids various errors later on. Fixes CVE-2012-0947. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | | | | | | | | | | | | | | | This properly synchronizes frame size changes between threads if subsequent threads abort decoding before frame size is initialized, i.e. it prevents the thread after that from ping-ponging back to the original value.
