Overview
This PR adds the ability to configure the maximum number of frames extracted from videos in Qwen2.5-VL through an environment variable
QWEN_VL_MAX_FRAMES. This enhancement improves the analysis of long videos by allowing users to extract more frames based on their hardware capabilities.Changes
QWEN_VL_MAX_FRAMESto override the defaultFPS_MAX_FRAMESvalueBackground & Motivation
When processing long videos (2+ hours), the current fixed limit of 768 frames provides insufficient temporal resolution. For example, a 2-hour video would only have about 1 frame every 9.4 seconds, making fine-grained event detection difficult. This change allows users with adequate hardware to increase the frame limit for better video analysis.
