# 刷机包是官方如下最新包:AIO-RV1126_RV1109-JD4_2021_0709_1611
# 执行如下程序:
VI->GetFrame
该开发流程对应的 DEMO 示例为 rkmedia_vi_get_frame_test.c
说明：设备输入保存至文件。演示 VI 没有 Bind 时如何取视频流。
快速使用：
#从摄像头节点 rkispp_scale0 抓取 10 帧图片并保存为 1080p.nv12 文件
./rkmedia_vi_get_frame_test-a /oem/etc/iqfiles/ -w 1920 -h 1080 -d rkispp_scale0 -o /tmp/1080p.nv12 -c 10
# 命令录取 10 帧图像数据，截取最后一帧来预览
# 使用 dd 跳过前 9 帧数据，得到最后一帧。3110400 = 1920 x 1080 x 3 / 2 一帧 NV12 数据大小
dd if=1080p.nv12 of=1080pl.nv12 bs=3110400 skip=9
# 使用 ffmpeg 把 NV12 图像转换为 PNG 格式。
fmpeg -y -f rawvideo -pix_fmt nv12 -ss 00:01 -r 1 -s 1920x1080 -i 1080pl.nv12 -frames:v 1 output.png
# 打开 output.png 预览。

# 报如下错误:

# ./rkmedia_vi_get_frame_test -a /oem/etc/iqfil

你有接 mipi 摄像头吗？
有 kernel log 吗？
自己用哪个仓库编译的？
固件本身就有自带有 rkmedia_vi_get_frame_test 二进制可执行文件，跑过吗？对比过吗？ 板蓝根 发表于 2021-7-15 09:07

谢谢版主回复.
你有接 mipi 摄像头吗？ ==> firefly官方的os04a10 模组, 用vlc可以正常推流预览.
有 kernel log 吗？==> 有,我想办法上传一下log,稍等.
自己用哪个仓库编译的？ ==> 我既用官方的烧录包AIO-RV1126_RV1109-JD4_2021_0709_1611测试,也用./build.sh aio-rv1126-jd4.mk 自己build, 结果一样.
固件本身就有自带有rkmedia_vi_get_frame_test 二进制可执行文件，跑过吗？对比过吗？==> 我就是用的固件本身的这个bin文件测试的.
kernel log 见附件.
亦可以看如下文字版本<文字版本log 无法上传,说有不良信息@@>.

你 vlc 能预览的话，那你跑的时候没有把应用关掉吗？关掉应该不能预览。cd /oem/;./Rklaunch-stop.sh; 如果不关掉会把摄像头占用的 1. 从kernellog 看, 虽然中间有丢log, 但camerasensor id 是读到了, 因为我这边已经能正常vlc preview了.
2. 从执行命令后error信息看,不管 -d 指定rkispp_scale0 还是其他entire, 都报错在video15 对应rkisp-input-params, 打开失败.
# ./rkmedia_vi_get_frame_test -a /oem/etc/iqfiles/ -w 1920 -h 1080 -d rkispp_scale0 -o /tmp/1080p.nv12 -c 10
:XCAM ERROR v4l2_device.cpp:657: device(/dev/video15) start failed
我的设备Core-1126-JD4 video15 对应rkisp-input-params
/sys/class/video4linux/video15/name:rkisp-input-params
3. 结论: 因为用的都是官方默认的固件, 程序, 摄像头, evb, 所有我怀疑是否此程序目前不兼容AIO-RV1126_RV1109-JD4_2021_0709_1611
故:
是否如下wik有值得完善的地方＜分析不当的地方， 辛苦版主指正＞？

1. 你所说的 vlc 可以预览，rtsp 推流的前一步骤取流和编码都是由 rkmedia 完成的，而你所用的系统自带的 rkmedia_vi_get_frame_test 是用同一个库编译出来的，所以 vlc 预览没有问题这个 demo 就不可能有问题。
2.你有根据 5 楼所说的验证过吗？
cd /oem/;./Rklaunch-stop.sh; 如果不关掉会把摄像头占用的
cd /oem/;./Rklaunch-stop.sh; 如果不关掉会把摄像头占用的
cd /oem/;./Rklaunch-stop.sh; 如果不关掉会把摄像头占用的
cd /oem/;./Rklaunch-stop.sh; 如果不关掉会把摄像头占用的
3. AIO-RV1126_RV1109-JD4_2021_0709_1611 这个固件我已经反复验证过无数次了，根据你的反馈我又去再验证了一次没有问题。

谢谢版主认真负责的工作态度, 给您点赞!
按照您post的步骤, step by step 成功了.
但我依旧通过如下步骤复现我提到的问题, 从而确认是Rklaunch 占用了摄像头. 这种问题以您的经验是如何快速确认的呢, 如何知道sensor 被占用了?
step1. reboot.
step2. vlc 推流验证成功,关闭vlc.
step3. 执行rkmedia_vi_get_frame_test...那串命令, 复现问题,输出error 信息和#1楼一致.
step4. 参考您的操作, ./RkLunch-stop.sh 后重新执行step3, 成功运行.
rkmedia vi 同个通道只能被初始化调用一次，你 vlc 可以预览那么，这个通道肯定被占用了，无论是什么应用调用肯定回报错的
