若源图像像素格式是 yuv420p16le(有 Y、U、V 三个 plane),位深是 16,分辨率仍然是 1280x720,则 Y plane 的 stride 值为 1280 x 16 / 8 = 2560,U plane stride 值为 640 x 16 / 8 = 1280,V plane stride 值为 640 x 10 / 8 = 1280。 若源图像像素格式是 p010le(有 Y、UV 两个 plane...

例如AV_PIX_FMT_YUV422 这个格式有 YUV 3 个分量,但是他只有一个 plane,因为他是一个 packetd 的格式,从上图可以看到 comp 里面的 plane 的值全是0 ,代表 3 个分量存储在同一行里面。 而还有一些格式,例如 AV_PIX_FMT_P010LE...
