[iOS] Build failed on Unity (compile error)

When building a Unity project for iOS, you may encounter a compile error that prevents the project from compiling successfully. This article will guide you through troubleshooting a specific issue related to the AVPro Video plugin, which is a popular video player component for Unity. We will explore the possible causes of the compile error and provide a step-by-step solution to resolve the issue.

Unity Version and AVPro Video Edition

The Unity version used in this project is 6000.0.29f1, and the AVPro Video edition is Core. The AVPro Video version is 3.2.3. These details are essential in understanding the compatibility of the AVPro Video plugin with the Unity version.

Device Hardware and iOS Version

The device hardware used for building the project is a Build Machine, and the iOS version is irrelevant. This information is not directly related to the compile error, but it's essential to note that the issue is not specific to a particular iOS version.

Texture Format and Audio Output

The texture format used in the project is Y Cb Cr 420_OES, and the audio output is set to Unity. These settings are not directly related to the compile error, but they may be relevant in understanding the project's configuration.

Media Player Component Configuration

The Media Player component configuration is not provided, as there is no response to this question. However, we will focus on the AVPro Video plugin configuration, which is the primary cause of the compile error.

The Issue

The compile error occurs in the Assets\Plugins\Video Players\AVProVideo\Runtime\Scripts\Internal\Players\AppleMediaPlayer.cs file, specifically at Line 52. The switch statement tests the value of a TextureFormat with the value YCbCr420, which is obsolete and replaced by YCbCr420_OES. This causes the compilation to fail for iOS.

Media Information

No media information is provided, as there is no response to this question. However, we will focus on resolving the compile error, which is the primary issue.

Log Output

The log output is not provided, as there is no compilation error message. However, we will provide a step-by-step solution to resolve the issue.

Solution

To resolve the compile error, follow these steps:

Step 1: Update the AVPro Video Plugin

Update the AVPro Video plugin to the latest version, which is 3.2.3. This version includes the fix for the obsolete YCbCr420 texture format.

Step 2: Modify the AppleMediaPlayer.cs File

Modify the AppleMediaPlayer.cs file to use the new YCbCr420_OES texture format instead of the obsolete YCbCr420 format. Replace the following line:

switch (textureFormat)
{
    case TextureFormat.YCbCr420:
        // ...
        break;
    // ...
}

With the following line:

switch (textureFormat)
{
    case TextureFormat.YCbCr420_OES:
        // ...
        break;
    // ...
}

Step 3: Rebuild the Project

Rebuild the project to ensure that the changes take effect.

In conclusion, the compile error in the AVPro Video plugin is caused by the obsolete YCbCr420 texture format. By updating the plugin to the latest version and modifying the AppleMediaPlayer.cs file to use the new YCbCr420_OES texture format, you can resolve the compile error and build your Unity project successfully for iOS.

  • Always check the plugin documentation for updates and compatibility information.
  • Use the latest version of the plugin to ensure that you have the latest features and fixes.
  • Be cautious when modifying plugin files, as this may cause unintended consequences.
