Hi @AI_Test,

We have example saving JPEG to SD card,
https://www.amebaiot.com/en/amebapro2-arduino-video-jpeg-sdcard/

May I know if you mean having a text overlay (Timestamp) on each snapshot?
Previously, a user asked for text overlay on video stream as well. It should be the same for the snapshot.

How to use opencv with amb82-mini

Hi @pcw0915, please refer to this example here. I hope that it can help you at this moment. Recently, NTPClient Library is added into the Arduino SDK and will be released in our next release, 4.0.6 (https://github.com/ambiot/ambpro2_arduino/tree/dev/Arduino_package/hardware/libraries/NTPClient). I have tried to overlay the time on the video stream using StreamRTSP->VideoOnly example. Hope it helps! VideoOnly.zip (1.3 KB)

You can take this as a reference.

hello,
thanks for your answer.
I only need to get the time synced to a NTP server.
Does it mean i need to wait for the next arduino sdk release to be able to use Ntpclient librairy?

Hi @AI_Test，

We will release this feature in the next release. But for now, you can use the pre release version first.

Input https://github.com/ambiot/ambpro2_arduino/raw/dev/Arduino_package/package_realtek_amebapro2_early_index.json in Preference and install 4.0.6-build20231220. NTP related API and demo will be included in this pre release.
