Gemini Video Summarization Sample

This sample is part of the AI Sample Catalog. To build and run this sample, you should clone the entire repository.

Description

This sample demonstrates how to generate a text summary of a video using Gemini Flash. Users can select a video, and the generative model will analyze its content to provide a concise summary, showcasing how to extract key information from video content with the Gemini API.

Gemini Video Summarization in action

How it works

The application uses the Firebase AI SDK (see How to run) for Android to interact with Gemini Flash. The core logic is in the VideoSummarizationViewModel.kt file. A generativeModel is initialized. When a user requests a summary, the video content and a text prompt are sent to the model, which then generates a text summary.

Here is the key snippet of code that calls the generative model:

val generativeModel =
    Firebase.ai(backend = GenerativeBackend.vertexAI())
        .generativeModel("gemini-2.5-flash")

val requestContent = content {
    fileData(videoSource.toString(), "video/mp4")
    text(promptData)
}
val outputStringBuilder = StringBuilder()
generativeModel.generateContentStream(requestContent).collect { response ->
    outputStringBuilder.append(response.text)
}
