The Changing Faces of YouTube: Brighter Future or Dimmer Devices?

YouTube’s latest shift to the AV1 codec promises enhanced video quality and reduced data usage on mobile devices. However, not everyone is rejoicing over this update, particularly those with older devices.

The evolution of video technology has seen a significant push towards higher quality, with 4K videos becoming more prevalent across platforms. This visible improvement in image quality is supported by less obvious changes under the hood, specifically in video codecs. The widely used H264 codec is gradually being replaced by AV1, which better handles high-resolution content, resulting in improved video quality. This transition, however, isn’t without its drawbacks.

Google has initiated support for the AV1 codec on Android devices, and YouTube is following suit. The implementation, developed by the creators behind the popular VLC media player, is touted as the most advanced solution to date. Since the Android March 2024 update (Google Play System Update), all Android devices running version 12 and newer now support this codec.

Despite the benefits, the shift has brought some challenges. Older and less powerful devices have been particularly affected, as they must decode the video software rather than using previous hardware solutions. This change increases the load on these devices, causing faster battery drain, as noted by Android Police.

On the flip side, the AV1 codec is more efficient in terms of data usage, which is a boon for users without unlimited data plans, allowing them to watch more videos without exhausting their data. However, improved battery life is not part of the package unless you own a newer device that supports hardware acceleration for AV1.

The reactions are mixed as YouTube continues to roll out this change across its app. The newer models will undoubtedly benefit from the new codec’s perks, but for many, the update might seem like a step back, particularly in terms of device longevity and battery sustainability.
