-MiniCPM-o 2.6 Video Analyzer - Hugging Face Spaces Version
-A Gradio interface for analyzing videos using MiniCPM-o 2.6
+MiniCPM-o 2.6 Multimodal Video Analyzer - Hugging Face Spaces Version
+A Gradio interface for comprehensive video + audio analysis using MiniCPM-o 2.6
+
+MULTIMODAL CAPABILITIES:
+- Video Analysis: Visual content, scenes, objects, actions, composition
+- Audio Analysis: Speech, music, sound effects, ambient audio, transcription
+- Combined Analysis: Synchronized audiovisual understanding and insights
+
+SHAPE MISMATCH ERROR HANDLING:
+This version includes robust handling for the common shape mismatch error:
+"RuntimeError: shape mismatch: value tensor of shape [1080] cannot be broadcast to indexing result of shape [1044]"
+
+The error occurs in the vision processing pipeline when there are inconsistencies between:
+- Calculated position embeddings (e.g., 1080 positions)
+- Attention mask dimensions (e.g., 1044 valid positions)
+
+IMPLEMENTED SOLUTIONS:
+1. Fallback Strategy 1: Reduces max_slice_nums to 1 for simpler processing  
+2. Fallback Strategy 2: Re-processes with fewer frames (16 max)
+3. Enhanced Error Messages: Provides actionable troubleshooting advice
+4. Video Diagnostics: Logs resolution and format information
+5. Audio Extraction: Librosa-based audio processing with error handling
+
+VIDEO COMPATIBILITY:
+- Preserves original video resolution and quality
+- Format: MP4, AVI, MOV, WebM supported
+- Duration: Any length (frames are sampled automatically)
+- Audio: Automatically extracted and analyzed when available
