Performance issues can occur when a video output sample has a 2D buffer, because winegstreamer currently outputs only to a linear buffer, which must then be copied into the 2D buffer. Worse, a linear lock of the 2D buffer requires the current contents to be copied to a linear buffer, even when we intend to overwrite it, because MF linear buffers do not support write-only locking. --- dlls/mf/tests/transform.c | 2 +- dlls/winegstreamer/aac_decoder.c | 2 +- dlls/winegstreamer/color_convert.c | 3 +- dlls/winegstreamer/gst_private.h | 3 +- dlls/winegstreamer/resampler.c | 2 +- dlls/winegstreamer/unixlib.h | 2 + dlls/winegstreamer/video_decoder.c | 3 +- dlls/winegstreamer/video_encoder.c | 2 +- dlls/winegstreamer/video_processor.c | 2 +- dlls/winegstreamer/wg_sample.c | 66 +++++++++++++++++++++++++--- dlls/winegstreamer/wg_transform.c | 42 +++++++++++++++--- dlls/winegstreamer/wma_decoder.c | 2 +- 12 files changed, 108 insertions(+), 23 deletions(-)
