Advanced tools
Chat about a video clip using ChatGPT hosted in OpenAI or Azure, or Gemini provided by Google
Chat about a video clip (or without the video clip) using the powerful OpenAI ChatGPT (hosted in OpenAI or Microsoft Azure) or Google Gemini (hosted in Google Could).
chat-about-video is an open-source NPM package designed to accelerate the development of conversation applications about video content. Harnessing the capabilities of ChatGPT from Microsoft Azure or OpenAI, as well as Gemini from Google, this package opens up a range of usage scenarios with minimal effort.
Key features:
To use chat-about-video in your Node.js application,
add it as a dependency along with other necessary packages based on your usage scenario.
Below are examples for typical setups:
# ChatGPT on OpenAI or Azure with Azure Blob Storage
npm i chat-about-video @azure/openai @ffmpeg-installer/ffmpeg @azure/storage-blob
# Gemini in Google Cloud
npm i chat-about-video @google/generative-ai @ffmpeg-installer/ffmpeg
# ChatGPT on OpenAI or Azure with AWS S3
npm i chat-about-video @azure/openai @ffmpeg-installer/ffmpeg @handy-common-utils/aws-utils @aws-sdk/s3-request-presigner @aws-sdk/client-s3
ChatGPT
To use ChatGPT hosted on OpenAI or Azure:
npm i @azure/openai
Gemini
To use Gemini hosted on Google Cloud:
npm i @google/generative-ai
ffmpeg
If you need ffmpeg for extracting video frame images, ensure it is installed. You can use a system package manager or an NPM package:
sudo apt install ffmpeg
# or
npm i @ffmpeg-installer/ffmpeg
Azure Blob Storage
To use Azure Blob Storage for frame images (not needed for Gemini):
npm i @azure/storage-blob
AWS S3
To use AWS S3 for frame images (not needed for Gemini):
npm i @handy-common-utils/aws-utils @aws-sdk/s3-request-presigner @aws-sdk/client-s3
There are two approaches for feeding video content to ChatGPT. chat-about-video supports both of them.
Frame image extraction:
Video indexing with Microsoft Azure:
chat-about-video supports sending Video frames directly to Google's API without a cloud storage.
ChatAboutVideo and Conversation are generic classes.
Use them without concrete generic type parameters when you want the flexibility to easily switch between ChatGPT and Gemini.
Otherwise, you may want to use concrete type. Below are some examples:
// cast to a concrete type
const castToChatGpt = chat as ChatAboutVideoWithChatGpt;
// you can also just leave the ChatAboutVideo instance generic, but narrow down the conversation type
const conversationWithGemini = (await chat.startConversation(...)) as ConversationWithGemini;
const conversationWithChatGpt = await (chat as ChatAboutVideoWithChatGpt).startConversation(...);
To access the underlying API wrapper, use the getApi() function on the ChatAboutVideo instance.
To get the raw API client, use the getClient() function on the awaited object returned from getApi().
Intermediate files, such as extracted frame images, can be saved locally or in the cloud.
To remove these files when they are no longer needed, remember to call the end() function
on the Conversation instance when the conversion finishes.
If you would like to customise how frame images are extracted and stored, consider these:
ChatAboutVideo, there's a property extractVideoFrames.
This property allows you to customise how frame images are extracted.
format, interval, limit, width, height - These allows you to specify your expectation on the extraction.deleteFilesWhenConversationEnds - This flag allows you to specify whether you want extracted frame images
to be deleted from the local file system when the conversation ends, or not.framesDirectoryResolver - You can supply a function for determining where extracted frame image files
should be stored locally.extractor - You can supply a function for doing the extraction.ChatAboutVideo, there's a property storage.
For ChatGPT, storing frame images in the cloud is recommended. You can use this property to customise
how frame images are stored in the cloud.
azureStorageConnectionString - If you would like to use Azure Blob Storage, you need to put
the connection string in this property. If this property does not have a value, ChatAboutVideo
would assume that you'd like to use AWS S3, and default AWS identity/credential will be picked up from the OS.storageContainerName, storagePathPrefix - They allows you to specify where those images should be stored.downloadUrlExpirationSeconds - For images stored in the cloud, presigned download URLs with expiration
are generated for ChatGPT to access. This property allows you to control the expiration time.deleteFilesWhenConversationEnds - This flag allows you to specify whether you want extracted frame images
to be deleted from the cloud when the conversation ends, or not.uploader - You can supply a function for uploading images into the cloud.In the options object passed to the constructor of ChatAboutVideo, there's a property clientSettings,
and there's another property completionSettings. Settings of the underlying model can be configured
through those two properties.
You can also override settings using the last parameter of startConversation(...) function on ChatAboutVideo,
or the last parameter of say(...) function on Conversation.
