What does H.264 Baseline profile primarily support?

The H.264 Baseline profile is primarily designed for low-complexity applications, such as video conferencing and mobile streaming, where low latency is crucial. This profile is optimized for real-time processing and ensures that video data can be encoded and decoded quickly, making it well-suited for environments where immediate playback is necessary.

Low latency video encoding is achieved through techniques that minimize buffering and processing delays, which are essential in applications like live streaming and video calls. The Baseline profile achieves this while still providing efficient compression, resulting in a balance between video quality and encoding speed.

In contrast, high-quality audio streaming, high-strength encryption, and the use of only B frames for compression do not capture the primary focus of the H.264 Baseline profile. Audio streaming pertains to audio codecs rather than video encoding profiles, encryption relates to securing data rather than encoding formats, and the statement about B frames does not accurately represent the capabilities of the Baseline profile, which can also utilize I frames and P frames in its encoding process.
