Abstract

fetched live from OpenAlex

Current rate control algorithms developed in the H.264 encoder are unable to address High Definition video streaming requirements over best effort networks such as the Internet. We propose a rate controller (RC) for H.264 high definition video conferencing (HDVC), specifically developed in the x264 codec: an open source and high performance H.264/AVC encoder. Called the Dynamic Constant Rate Factor (DCRF), our RC tries to provide the best possible quality in terms of the current bandwidth available at a given instance of video streaming. The proposed method is analyzed from different aspects including network bandwidth, frame size, PSNR and SSIM measurements. In addition to the objective tests, DCRF is evaluated by human observers for subjective performance evaluation. The results prove that DCRF provides better results than current RC methods for HDVC.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
