thansk for support in advanced, I saw couple examples for medial control in SDK,  
but seem most sample are processing video streaming, is there snapshot example ?  
I would like to capture one frame every 20ms and store a jpeg format.

thank you in advanced.

I checked Arduino(camera to lcd) and rtos SDK and I put same setting in both project.

Arduino Project is working well, but tried to implement same with rtos SDK and got fail.

the camera ctx in rtos is below (should be same as Arduino one)

with above, I did implement snapshot callback and send snapshot command during while loop.

seems snapshot is not triggered with rtos sdk.

I found out the debug messages are different

rtos sdk:

arduino debug:

I saw FW version are different and the heap size of VOE is big different also (11722496 and 7528192).

appreciated for your help and let me know if you need mroe information.

Hi @sl526,

Have you tried this example?

> <https://github.com/Ameba-AIoT/ameba-rtos-pro2/blob/main/project/realtek_amebapro2_v0_example/src/mmfv2_video_example/mmf2_video_example_v1_snapshot_init.c>

You may need to uncomment line 37,  
#define ENABLE\_SD\_SNAPSHOT //Enable the snapshot to sd card

thank you Pammy,

I think it should be still working w/o enabling SD storage and below is the debug message.

there is a thread to send CMD\_VIDEO\_SNAPSHOT every 10 sec and expect to see snapshot result

“printf(“snapshot size=%d\n\r”, jpeg\_len);” → but I did **not** see this and it reset in 30 sec.

Hi @sl526，

From your log, I noticed the following error:

`VOE command 0x206 fail ret 0x0`

May I confirm whether you have modified `sensor.h` and changed `USE_SENSOR` to `SENSOR_F37`?

I’ve attached my configuration for your reference.

 ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/b/b8126d9f1f395a4e42fdfb57c5090b979dbfacd8.png)

This example uses a double-encoder configuration, which allows H.264 video streaming while also supporting snapshot capture.

The snapshot function is triggered using the AT command:

`SNAP=SNAPS`

After entering the AT command, you should see,

> # 
> 
> SNAP=SNAPS  
> capture\_snapshot\_cb snapshot size=58539  
> jpeg sd:/0.jpg

> SNAP=SNAPS  
> capture\_snapshot\_cb snapshot size=216051

I uncommented `#define ENABLE_SD_SNAPSHOT //Enable the snapshot to sd card` to save JPEG into a SD card.

Hello @Pammy ,

Appreciated for your support !!

I did try to enable SD w/ FAT32 64G and SD mount is good. but still got fail.  
I think VOE command 0x206 fail return 0x0 is when sending CMD\_VIDEO\_APPLY and  
I saw this in other projects also.

is there possible root cause ?  
I did test my board with Arduino example and it is working, so assume my HW is good.

Hi @sl526 ,

Some possible root causes for `VOE command 0x206 fail ret 0x0` can be found in this topic.

> Hi @Hsu_Shawn, I have edited the previous message and added the answer for [6.1]. [6.1] Error code ret=0x98600800 indicates that video\_open() failed at the driver layer. This return value corresponds to the ERR\_ID\_DRV\_VIDEO\_INVALID\_CROP\_SIZE error. However, we are unable to share the mapping table at this time as it contains confidential information. If you encounter any similar errors in the future, feel free to let us know, and we will be happy to assist you in identifying the issue. VO…

However, one common cause is that the sensor configuration is not set correctly.

Could you also share your amebapro2\_sensor\_set.json file (in `\project\realtek_amebapro2_v0_example\GCC-RELEASE\build\application`) after build so that I can verify the sensor configuration?

You can also share your code with us if you have made any modifications to the original example. This will help us compare the changes and identify any possible cause of the issue.

The correct command is SNAP=SNAPS.

Can I also confirm that you build the example using this[repo](https://github.com/Ameba-AIoT/ameba-rtos-pro2)?

Here’s my log for your reference.

hello @Pammy

thanks for you information, I tested with ameba-rtos-pro2 SDK 1.0.1 and it is working.

you can see the last message in below log and it does trigger the callback (snapshot size xxxxx).

I expect it might be caused by different FW version

Working one

- voe :RTL8735B\_VOE\_1.6.1.0
- sensor:RTL8735B\_VOE\_1.5.7.0
- hal :RTL8735B\_VOE\_1.6.1.0

the problem I have is

- voe :RTL8735B\_VOE\_1.7.1.0
- sensor:RTL8735B\_VOE\_1.7.1.0
- hal :RTL8735B\_VOE\_1.7.1.0

the working one in you log → I did not see voe/sensor/hal version, so I think you are using SDK 1.0.0. (I did test 1.0.0 and it is also working)
