Video playback stutter for WebRTC due to keyframe processing, especially with high-profile settings and slower presets.

[Mohit-3196]

Short description

Brief description of what happened

Environment

• Operating system and version: N/A
• Java version: Java 17
• Ant Media Server version: v2.13.2
• Browser name and version: N/A

Steps to Reproduce

1. Publish a RTMP stream with 60 FPS video using High profile, slow preset & 0 b-frames.
2. Observe WebRTC playback, especially at keyframes, where stuttering occurs.

Expected behavior

Smooth WebRTC play.

Actual behavior

There is a noticeable stutter on keyframes, especially with High profile and Slow preset settings. The issue is less severe when using the Software encoder (x264) with the Baseline profile and the fastest preset, as keyframes contain minimal data. However, with higher profiles and slower presets, keyframes become larger, leading to increased stutter.
