Passing in prompts to aws lambda function.

To pass multiple prompts to your AWS Lambda function for Nova Reels multi-shots, you can modify your Kotlin code to include multiple prompts in the JSON payload. Here's how you can adjust your code to pass two prompts:

1. First, ensure you have two input fields or a way to capture two separate prompts from the user.

2. Then, modify your code to create a JSON payload with both prompts:

val userPrompt1 = inputField1.text.toString()
val userPrompt2 = inputField2.text.toString()

val jsonPayload = """
    {
        "prompt1": "$userPrompt1",
        "prompt2": "$userPrompt2"
    }
""".trimIndent()

val requestBody = jsonPayload.toRequestBody("application/json".toMediaType())

val request = Request.Builder()
    .url(url)
    .post(requestBody)
    .build()

In your AWS Lambda function, you can then retrieve these prompts from the event parameter:

def lambda_handler(event, context):
    # Extract the prompts from the event
    body = json.loads(event['body'])
    prompt1 = body['prompt1']
    prompt2 = body['prompt2']

    model_input = {
        "taskType": "TEXT_VIDEO",
        "textToVideoParams": [
            {"text": prompt1},
            {"text": prompt2}
        ],
        "videoGenerationConfig": {
            "durationSeconds": 6,
            "fps": 24,
            "dimension": "1280x720",
            "seed": 33,
        },
    }

    # Rest of your Lambda function code...

This approach allows you to send multiple prompts from your Android app to your Lambda function, which can then use them for the Nova Reels multi-shot feature. Remember to adjust the Lambda function to handle multiple prompts in the textToVideoParams section of the model_input dictionary.
