Agora 的自適應視頻優化 (AVO) 技術可動態優化從捕捉到回放的每個步驟的性能,以提供卓越的實時視頻質量。

SANTA CLARA, Calif., May 1, 2024 /PRNewswire/ -- Agora, Inc. (NASDAQ: API), a pioneer and leading platform for real-time engagement APIs, today unveiled its latest innovation, Adaptive Video Optimization (AVO) along with support for the AV1 video codec. This advanced technology harnesses the power of machine learning to dynamically adjust parameters at every step from capture to playback to deliver an enhanced live video streaming experience.

加利福尼亞州聖克拉拉,2024 年 5 月 1 日 /PRNewswire/-- Agora, Inc. (納斯達克股票代碼:API)是實時互動API的先驅和領先平台,今天公佈了其最新創新——自適應視頻優化(AVO)以及對AV1視頻編解碼器的支持。這項先進的技術利用機器學習的力量,在從捕捉到回放的每個步驟中動態調整參數,從而提供增強的實時視頻流體驗。

In today's fast-paced digital world, live video calling and streaming often encounters hurdles such as unstable network conditions, packet loss, and limited bandwidth. These challenges can result in freezing, stuttering, grainy video, and dropped connections, diminishing the real-time video experience and negatively impacting user engagement. Adaptive Video Optimization uses a series of advanced machine learning algorithms to address these common issues. By optimizing video quality in real time based on network conditions, device capabilities, and available bandwidth, AVO ensures the highest possible video quality and optimal performance even under varying network scenarios.

在當今快節奏的數字世界中,實時視頻通話和流媒體經常遇到諸如不穩定的網絡狀況、丟包和有限的帶寬等障礙。這些挑戰可能導致卡頓、卡頓、視頻顆粒狀和連接中斷,從而降低實時視頻體驗並對用戶參與度產生負面影響。自適應視頻優化使用一系列高級機器學習算法來解決這些常見問題。通過根據網絡狀況、設備功能和可用帶寬實時優化視頻質量,AVO 即使在不同的網絡場景下也能確保儘可能高的視頻質量和最佳性能。

"Reliable and high-quality live streaming is essential in today's video-dominated media landscape," stated Tony Zhao, CEO and Co-Founder of Agora. "Our Adaptive Video Optimization technology enables smooth delivery of every video call and livestream—despite network variability, user's location or device type. These improvements empower Agora's customers to provide the highest-quality live video user experience."

Agora首席執行官兼聯合創始人Tony Zhao表示:“在當今以視頻爲主的媒體格局中,可靠和高質量的直播至關重要。“無論網絡變化、用戶位置或設備類型如何,我們的自適應視頻優化技術都能順利交付每一次視頻通話和直播。這些改進使Agora的客戶能夠提供最高質量的實時視頻用戶體驗。”

Agora's commitment to delivering a seamless real-time video experience with AVO rests on three core pillars:

Agora 致力於通過 AVO 提供無縫的實時視頻體驗,其基礎是三個核心支柱:

  • Optimized Image Quality: Ensures that every frame is crisp, with enhanced contrast and vibrant details that make the viewing experience clearer and more engaging.
  • Unmatched Video Fluency: Eliminates common streaming issues like buffering and stuttering, providing a smooth and natural flow.
  • Ultra-Low Latency: Allows users to interact in real-time, whether with hosts or other viewers, and enjoy quick loading times and instant first-frame rendering for seamless transitions between video streams.
  • 優化的圖像質量:確保每幀都清晰,具有增強的對比度和生動的細節,使觀看體驗更清晰、更具吸引力。
  • 無與倫比的視頻流暢度:消除了緩衝和卡頓等常見的流媒體問題,提供流暢自然的流暢流動。
  • 超低延遲: 允許用戶與主持人或其他觀衆進行實時互動,享受快速加載時間和即時第一幀渲染,從而實現視頻流之間的無縫過渡。

AVO takes a comprehensive machine learning approach to ensure the highest quality video streaming experience by optimizing every stage of the video processing pipeline — pre-processing, encoding, transmission, decoding, and post-processing. A key component of this solution is Agora's Coding Technology (ACT), designed to optimize user experiences by dynamically selecting the best video codec (like AV1 or VP9) based on device capabilities and interoperability requirements. By employing advanced techniques and cutting-edge compression methods, the technology adapts, configuring parameters dynamically and ensures crisp visuals, efficient bandwidth utilization, and a consistent, high-quality experience for all users, from the moment the video is captured to the final display on the viewer's screen.

AVO 採用全面的機器學習方法,通過優化視頻處理管道的每個階段(預處理、編碼、傳輸、解碼和後處理)來確保最高質量的視頻流媒體體驗。該解決方案的關鍵組件是Agora的編碼技術(ACT),該技術旨在根據設備功能和互操作性要求動態選擇最佳視頻編解碼器(如AV1或VP9)來優化用戶體驗。通過採用先進的技術和尖端的壓縮方法,該技術可以進行調整,動態配置參數,並確保從視頻捕捉到最終顯示在觀衆屏幕上,爲所有用戶提供清晰的視覺效果、高效的帶寬利用率和一致的高質量體驗。

From video capture through playback, the technology continuously adapts to changing network conditions and device capabilities, guaranteeing a seamless streaming experience. Any imperfections that may arise during transmission are rapidly mitigated, and the final video is polished to provide lifelike clarity, delivering a superior real-time video experience for scenarios ranging from telehealth consultations to live shopping and social media.

從視頻捕獲到播放,該技術不斷適應不斷變化的網絡條件和設備功能,從而確保無縫的流媒體體驗。傳輸過程中可能出現的任何缺陷都會迅速得到緩解,並對最終視頻進行了打磨,以提供逼真的清晰度,爲從遠程醫療諮詢到現場購物和社交媒體等場景提供卓越的實時視頻體驗。

"Agora's Adaptive Video Optimization (AVO) drastically improved the real-time video experience in our app," said Ellard Capiral, VP of Engineering at social live streaming app KUMU. "Users get smooth, high-quality video without freezes—even on slow connections and older devices. Since implementing AVO, we've seen a 30% increase in session length and engagement."

社交直播應用程序KUMU的工程副總裁埃拉德·卡皮拉爾說:“Agora的自適應視頻優化(AVO)極大地改善了我們應用程序的實時視頻體驗。”“即使在連接速度慢和設備較舊的情況下,用戶也能獲得流暢、高質量的視頻,也不會出現卡頓現象。自實施AVO以來,我們的會話時長和參與度增加了30%。”
