Signed-off-by: Derek Lesho dlesho@codeweavers.com --- v2: - Apply Nikolay's diff in order to remove the need for images to have an associated fourcc. - Fix buffer overflow. (IMC2 and IMC4's buffer->max_length needed to be expanded as NV12's is). --- dlls/mfplat/buffer.c | 59 ++++++++++++++++++++++++++++++++++---- dlls/mfplat/tests/mfplat.c | 42 ++++++++++++++++++++++++++- 2 files changed, 94 insertions(+), 7 deletions(-)
