There are no devices installed for the specified ADAPTORNAME

本文档详细介绍了在MATLAB_r2014a中使用Mac电脑内置摄像头录制avi视频时遇到的问题及解决步骤。首先,通过imaqhwinfo检查设备,发现错误提示"There are no devices installed for the specified ADAPTORNAME"。解决方法是通过supportPackageInstaller安装OS Generic Video Interface,并验证设置。最后成功创建videoinput对象,使用正确的设备ID和视频格式进行视频录制。

目标: matlab_r2014a利用mac电脑自带摄像头录制avi视频
步骤: 1.在matlab窗口命令行输入info=imaqhwinfo,查看已安装的图像采集设备。
2. info =

InstalledAdaptors: {'dcam'}
    MATLABVersion: '8.3 (R2014a)'
      ToolboxName: 'Image Acquisition Toolbox'
   ToolboxVersion: '4.7 (R2014a)'

3. 创建一个视频输入对象:
obj=videoinput(‘dcam’,1,’YUY2_320x240’);
问题:There are no devices installed for the specified ADAPTORNAME. See IMAQHWINFO.
原因:没有在matlab中安装对象摄像头的支持包
解决方法:1. 输入supportPackageInstaller,安装OS Generic Video Interface,GigE Vision Hardware(如果只用电脑自带摄像头可不安装)
2. 再次info=imaqhwinfo
3. info =

InstalledAdaptors: {'dcam'  'gige'  'macvideo'}
    MATLABVersion: '8.3 (R2014a)'
      ToolboxName: 'Image Acquisition Toolbox'
   ToolboxVersion: '4.7 (R2014a)'

4. 终于,adaptorname为 ‘macvideo’, 输入imaqhwinfo(‘macvideo’) 查看相关信息:

ans =

### RK3588 Linux Kernel Source Code Download For downloading the RK3588 Linux kernel source code, one approach is to visit the official Rockchip GitHub repository or other designated repositories provided by Rockchip. The command line can also be used within a specific directory structure as indicated in similar development environments: To begin with, ensure that Git is installed on the system since it will facilitate cloning the repository containing the necessary files. Once this prerequisite is met, executing commands such as `git clone` followed by the URL of the RK3588 Linux kernel repository allows for obtaining all relevant sources. Alternatively, when working inside an environment like the one mentioned where build scripts are utilized for compiling kernels[^1], there might already exist pre-configured methods or documentation guiding users through acquiring and setting up the correct version of the Linux kernel source tailored specifically towards RK3588 platforms. Moreover, developers interested in more detailed operations related to building images or flashing devices may find useful tools located at specified paths which could indirectly assist in understanding how to properly set up and work with these sources once downloaded[^2]. Finally, those looking into advanced topics concerning media processing capabilities offered by hardware acceleration features available on RK3588 SoCs would benefit from exploring additional resources discussing implementation details regarding decoding and streaming functionalities[^3]. ```bash # Example Command to Clone Repository (Hypothetical URL) $ git clone https://github.com/rockchip-linux/kernel.git -b rk3588_branch_name ``` --related questions-- 1. What are some common issues encountered while downloading large repositories using Git? 2. How does one verify the integrity of downloaded kernel source codes? 3. Can you explain what changes need to be made after getting the source before compilation? 4. Where can I find comprehensive guides about configuring and customizing the RK3588 Linux kernel?
