Introduction


This explanation assumes that the i-PRO camera application development environment has been completed.
If you are not ready to build the development environment, please refer to here to complete it.

Also, in this tutorial, the SDK installation directory is described as ${SDK_DIR}.

Operation overview


mp4rec_app is a sample application that creates MP4 of video data.

 

External libraries required for operation


No special mention.

 

Directory path of the sample app


The C/C++ source code is stored below.

${SDK_DIR}/src/adamapp/mp4rec_app

The Python source code is stored below.

${SDK_DIR}/src/adamapp-py/mp4rec_app

 

How to build the sample app (C/C++)


This article describes how to build it as AdamApp.
If you want to build it as Container AdamApp for Azure IoT Edge, see below.

Development tutorial (Container AdamApp for Azure IoT Edge) - Technology Partner FAQ (En) - Confluence (atlassian.net)

Load the build environment settings file in the SDK installation directory.

$ cd ${SDK_DIR} $ source setup_env.sh ipro-ambaCV2X

Set the build environment according to each environment.
Here, specify ipro-ambaCV2X.

 

make.

$ cd src/adamapp/mp4rec_app $ make

It is successful if the .ext file is created in ${SDK_DIR}/src/adamapp/mp4rec_app.

 

Install it on the camera (eg, you can install from the green frame in the image below). Select the created .ext file and install it.
Open the app screen (red frame button in the image below).

 

It is successful if a character string like the image below is displayed.

How to use the sample app(C/C++ and Python)


■ Method using a TFTP server

By default, mp4 files are generated in the mp4 folder of the TFTP server (192.168.0.3). Build your own TFTP server.

Press Rec Start to start recording. Press Rec Stop to stop recording.

 

■ Method using an SD card

Next, set the SD card inserted in the camera to save mp4 files and run the sample application. Turn on "Ext. software mode" from the red frame below and press the Set button.

Press the AppPrefs button of the sample application from the ADAM OPERATION UI.

Uncheck "Send tftp Enable", apply and close.

Press Rec Start to start recording. Press Rec Stop to stop recording.

An mp4 file is generated in the {SD card mount volume}\adamapp\mp4rec_app\yyyymmdd folder.
