# Función Lambda
def lambda_handler(event, context):
    search_results = search_videos("TED Talks", max_results=10)
    transcripts = []
    for video_id, video_title, published_at, channel_title in tqdm(search_results, desc="Procesando videos"):
        try:
            transcript = get_transcript(video_id)
            processed_transcript = process_transcript(transcript)
            transcripts.append(processed_transcript)
            
        except NoTranscriptFound:
                pass

        "body": json.dumps(str({
            "transcripts": len(transcripts),
            "sample": str(str(transcripts[-1][:30])+'...')
        })
        )
    }

def search_videos(query, max_results=5):
    youtube = build("youtube", "v3", developerKey=YOUTUBE_API_KEY)

    for item in response['items']:
        video_id = item['id']['videoId']
        video_title = item['snippet']['title']
        published_at = item['snippet']['publishedAt']
        channel_title = item['snippet']['channelTitle']
        videos.append((video_id, video_title, published_at, channel_title))

    return videos

    try:
        transcript = YouTubeTranscriptApi.get_transcript(video_id)
        return transcript
    except (TranscriptsDisabled, VideoUnavailable, NoTranscriptFound) as e:
        print(f"Error : No Subtitulos ", e)
        return ''
    except Exception as e:
        print(f"Error inesperado con proxy: {e}")
        return ''

def process_transcript(transcript):
    return " ".join([item['text'] for item in transcript])
