Michael Niedermayer	3af9d8269e	avcodec/g2meet: check the return code of ff_set_dimensions() This is currently redundant as the checks before it are tighter than the checks in ff_set_dimensions() but its more robust not to depend on that.

Alexandra Khirnova	9b8d11a76a	avcodec: Use av_reallocp where suitable Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Kostya Shishkov	01f6df01b6	go2meeting: disallow tile dimensions that are not multiple of 16 Original decoder seems to always use 176x128 tiles anyway and this helps avoiding lots of issues with odd tile sizes in fuzzed files. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Michael Niedermayer	e07ac727c1	avcodec/g2meet: Fix framebuf size Currently the code can in some cases draw tiles that hang outside the allocated buffer. This patch increases the buffer size to avoid out of array accesses. An alternative would be to fail if such tiles are encountered. I do not know if any valid files use such hanging tiles. Fixes Ticket2971 Found-by: ami_stuff Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
