Add auto file extension and H.264/H.265/MP4 format options to Merge module
Issues fixed: - Missing file extensions caused FFmpeg errors (user's job 234 failure) - Limited codec options (only copy or H.265) - Manual codec mode selector was redundant Changes: 1. Auto file extension handling: - Automatically adds/corrects extension based on selected format - .mkv for MKV/Blu-ray formats - .mpg for DVD formats - .mp4 for MP4 formats - Validates and fixes extension in addMergeToQueue 2. Expanded format options: - MKV (Copy streams) - stream copy, no re-encoding - MKV (H.264) - re-encode with H.264, CRF 23 - MKV (H.265) - re-encode with H.265, CRF 28 - MP4 (H.264) - H.264 + AAC audio, web-optimized - MP4 (H.265) - H.265 + AAC audio, web-optimized - DVD NTSC/PAL (16:9 and 4:3) - Blu-ray (H.264) 3. Removed redundant codec mode selector: - Format dropdown now explicitly includes codec choice - Cleaner, more intuitive UI - Backward compatible with old queue jobs Extension is auto-updated when: - User selects a different format (updates existing path extension) - User adds merge to queue (validates/fixes before encoding) - Prevents errors from missing or wrong file extensions 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
