from requests_aws4auth import AWS4Auth
from requests.auth import HTTPBasicAuth

# OpenSearch connection configuration
# host="your-host.aos.us-east-1.on.aws"
host="search-new-domain-mbgs7wth6r5w6hwmjofntiqcge.aos.us-east-1.on.aws"
port = 443  # Default HTTPS port

# Get OpenSearch username secret from Secrets Manager
opensearch_username=secrets_manager_client.get_secret_value(
    SecretId="AOS_username"
)
opensearch_username_string=json.loads(opensearch_username["SecretString"])["AOS_username"]

# Get OpenSearch password secret from Secrets and techniques Supervisor
opensearch_password = secrets_manager_client.get_secret_value(
    SecretId="AOS_password"
)
opensearch_password_string=json.hundreds(opensearch_password["SecretString"])["AOS_password"]

auth=(opensearch_username_string, opensearch_password_string)

# Create the consumer configuration
client_aos = OpenSearch(
    hosts=[{'host': host, 'port': port}],
    http_auth=auth,
    use_ssl=True,
    verify_certs=True,
    connection_class=RequestsHttpConnection

from opensearchpy.helpers import bulk

def generate_actions(duties, video_files):
    rely = 0
    for job in duties:
        # Verify if video embeddings can be found
        if job.video_embedding shouldn't be None and job.video_embedding.segments shouldn't be None:
            embeddings_doc = job.video_embedding.segments
            
            # Generate actions for bulk indexing
            for doc_id, elt in enumerate(embeddings_doc):
                yield {
                    '_index': index_name,
                    '_id': doc_id,
                    '_source': {
                        'embedding_field': elt.embeddings_float,
                        'video_title': video_files[count],
                        'segment_start': elt.start_offset_sec,

print(f" Mannequin: {audio_res.model_name}")

# Extract and examine the generated audio embeddings
if audio_res.audio_embedding shouldn't be None and audio_res.audio_embedding.segments shouldn't be None:
    print_segments(audio_res.audio_embedding.segments)

# Retailer the embedding vector for search
vector_search = audio_res.audio_embedding.segments[0].embeddings_float
print("Generated Audio Embedding Vector:", vector_search)

Key factors:

• The Marengo-retrieval-2.7 mannequin is used to generate a dense vector embedding for the enter audio.
• The embedding captures the semantic options of the audio, resembling rhythm, tone, and patterns, enabling efficient matching with video embeddings

Carry out vector search in OpenSearch Service

After the audio embedding is generated, you employ it as a question vector to carry out a k-nearest neighbor (kNN) search in OpenSearch:

# Carry out vector search
query_vector = vector_search
audio_to_video_search = search_similar_segments(query_vector)
# print(text_video_search)
    
print_search_results(audio_to_video_search)

Anticipated output

The next reveals video segments retrieved from OpenSearch Service primarily based on their similarity to the enter audio.

Search Outcomes:
--------------------------------------------------

Consequence 1:
Video: island.mp4
Time Vary: 6.0 - 12.0
Similarity Rating: 0.2855

Consequence 2:
Video: robin-bird.mp4
Time Vary: 18.0 - 21.087732
Similarity Rating: 0.2841

Consequence 3:
Video: robin-bird.mp4
Time Vary: 12.0 - 18.0
Similarity Rating: 0.2837

Consequence 4:
Video: island.mp4
Time Vary: 0.0 - 6.0
Similarity Rating: 0.2835

Right here discover that segments from each movies are returned with a low similarity rating.

Step 9: Performing images-to-video search

You should utilize image-to-video search to retrieve video segments which are visually just like a given picture. Through the use of TwelveLabs’ picture embedding capabilities and OpenSearch Service’s vector search performance, you’ll be able to match visible options from a picture with video embeddings within the index. Right here’s methods to implement this step:

Generate Picture Embeddings

To carry out the search, you first convert the enter picture right into a vector illustration utilizing the TwelveLabs Embed API:

# Create picture embeddings for the enter picture file
image_res = twelvelabs_client.embed.create(
    model_name="Marengo-retrieval-2.7",
    image_file="image-data.jpg",  # Exchange along with your desired picture file
)

# Print particulars of the generated embedding
print(f"Created picture embedding: model_name={image_res.model_name}")
print(f" Mannequin: {image_res.model_name}")

# Extract and examine the generated picture embeddings
if image_res.image_embedding shouldn't be None and image_res.image_embedding.segments shouldn't be None:
    print_segments(image_res.image_embedding.segments)

# Retailer the embedding vector for search
vector_search = image_res.image_embedding.segments[0].embeddings_float
print("Generated Picture Embedding Vector:", vector_search)

Key factors:

• The Marengo-retrieval-2.7 mannequin is used to generate a dense vector embedding for the enter picture.
• The embedding captures visible options resembling shapes, colours, and patterns, enabling efficient matching with video embeddings

Carry out vector search in OpenSearch

After the picture embedding is generated, you employ it as a question vector to carry out a k-nearest neighbor (kNN) search in OpenSearch:

# Carry out vector search
query_vector = vector_search
image_to_video_search = search_similar_segments(query_vector)
# print(text_video_search)
    
print_search_results(image_to_video_search)

Anticipated output

The next reveals video segments retrieved from OpenSearch primarily based on their similarity to the enter picture.

Search Outcomes:
--------------------------------------------------

Consequence 1:
Video: island.mp4
Time Vary: 6.0 - 12.0
Similarity Rating: 0.5616

Consequence 2:
Video: island.mp4
Time Vary: 0.0 - 6.0
Similarity Rating: 0.5576

Consequence 3:
Video: robin-bird.mp4
Time Vary: 12.0 - 18.0
Similarity Rating: 0.4592

Consequence 4:
Video: robin-bird.mp4
Time Vary: 18.0 - 21.087732
Similarity Rating: 0.4540

Observe that picture of an ocean was used to look the movies. Video clips from the island video are retrieved with a better similarity rating within the first 2 outcomes.
