从原始视频中提取帧

如何解决从原始视频中提取帧

我将配置设置为：

v4l2-ctl -v pixelformat=pRCC,width=4056,height=3040
v4l2-ctl -p 10

然后获取帧：

v4l2-ctl --stream-mmap=3 --stream-count=100 --stream-to=test.avi

成功结束。现在我一直在尝试从这个视频文件中提取帧并将它们转换为 RGB 以供查看。

我有两种相机操作模式，第一种是直接将它连接到地址总线，而不是将格式结果列为：

v4l2-ctl --list-formats-ext

ioctl: VIdioC_ENUM_FMT
Type: Video Capture

[0]: 'pRCC' (12-bit Bayer RGRG/GBGB Packed)
    Size: discrete 4056x3040
    Size: discrete 2028x1520
    Size: discrete 2028x1080
[1]: 'RG12' (12-bit Bayer RGRG/GBGB)
    Size: discrete 4056x3040
    Size: discrete 2028x1520
    Size: discrete 2028x1080
[2]: 'pRAA' (10-bit Bayer RGRG/GBGB Packed)
    Size: discrete 1012x760
[3]: 'RG10' (10-bit Bayer RGRG/GBGB)
    Size: discrete 1012x760

如果我通过操作系统连接，那么结果是：

ioctl: VIdioC_ENUM_FMT
Type: Video Capture

正如我所提到的，我试图尽可能快地获得未触及的 12 位数据，然后我可以在 Python 中查看像素数据，最好（我也愿意接受其他建议）。

如果有经验的用户提供一些解决方案，我会很高兴。
