只需在缩放之前将gdi帽用作第一个输入并运行colorkey *。
ffmpeg -y -i gameplay.avi -f gdigrab -framerate 30 -draw_mouse 0 -i title="NohBoard v1.2.2" -filter_complex "[1:v]colorkey=0x00FF00:similarity=.200,scale=560x180 [kb]; [0:v][kb] overlay=x=W-w-520:y=H-h-0 [done]" -shortest -map [done] test.mkv
- gdigrab发送RGB帧，因此colorkey将比chromakey更快，而抠像需要在抠像之前转换为YUV像素。

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
