开发板使用最新固件,未进行修改,使用购买的8M摄像头,但使用v4l2-ctrl查看支持的分辨率最大只能到1920*1080,请问如何输出8M图像?此外,为什么/dev/video*节点从video0-video11这么多,哪一个对应着摄像头? root@firefly:~# v4l2-ctl -d /dev/video0 --list-formats-ext ioctl: VIDIOC_ENUM_FMT Type: Video Capture Multiplanar [0]: 'NV16' (Y/CbCr 4:2:2) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [1]: 'NV61' (Y/CrCb 4:2:2) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [2]: 'NV12' (Y/CbCr 4:2:0) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [3]: 'NV21' (Y/CrCb 4:2:0) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [4]: 'YUYV' (YUYV 4:2:2) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [5]: 'YVYU' (YVYU 4:2:2) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [6]: 'UYVY' (UYVY 4:2:2) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [7]: 'VYUY' (VYUY 4:2:2) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [8]: 'RGB3' (24-bit RGB 8-8-8) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [9]: 'BGR3' (24-bit BGR 8-8-8) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [10]: 'RGBP' (16-bit RGB 5-6-5) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [11]: 'BGRH' (18-bit BGRX 6-6-6-14) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [12]: 'RGGB' (8-bit Bayer RGRG/GBGB) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [13]: 'GRBG' (8-bit Bayer GRGR/BGBG) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [14]: 'GBRG' (8-bit Bayer GBGB/RGRG) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [15]: 'BA81' (8-bit Bayer BGBG/GRGR) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [16]: 'RG10' (10-bit Bayer RGRG/GBGB) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [17]: 'BA10' (10-bit Bayer GRGR/BGBG) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [18]: 'GB10' (10-bit Bayer GBGB/RGRG) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [19]: 'BG10' (10-bit Bayer BGBG/GRGR) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [20]: 'RG12' (12-bit Bayer RGRG/GBGB) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [21]: 'BA12' (12-bit Bayer GRGR/BGBG) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [22]: 'GB12' (12-bit Bayer GBGB/RGRG) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [23]: 'BG12' (12-bit Bayer BGBG/GRGR) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [24]: 'BYR2' (16-bit Bayer BGBG/GRGR) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [25]: 'GB16' (16-bit Bayer GBGB/RGRG) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [26]: 'GR16' (16-bit Bayer GRGR/BGBG) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [27]: 'RG16' (16-bit Bayer RGRG/GBGB) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [28]: 'Y16 ' (16-bit Greyscale) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [29]: 'GREY' (8-bit Greyscale) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [30]: 'EBD8' (Embedded data 8-bit) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [31]: 'SPD6' (Shield pix data 16-bit) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [32]: 'Y12 ' (12-bit Greyscale) Size: Stepwise 64x64 - 1920x1080 with step 8/8 [33]: 'Y10 ' (10-bit Greyscale) Size: Stepwise 64x64 - 1920x1080 with step 8/8 root@firefly:~# ls /dev/video* /dev/video0 /dev/video11 /dev/video4 /dev/video7 /dev/video-dec0 /dev/video1 /dev/video2 /dev/video5 /dev/video8 /dev/video-enc0 /dev/video10 /dev/video3 /dev/video6 /dev/video9 |
