| Feature | Benefit | |---------|---------| | M3U8 / MPD detection | Works with modern adaptive streams, not just direct .mp4 links | | Quality selection | Choose resolution (up to 4K if available) | | Audio-only extraction | Save as MP3 or M4A for podcasts/music | | Batch downloads | Queue multiple videos from the same site | | Smart naming | Automatically uses page title as filename | | Firefox-native | Lightweight, no external software required |

For power users creating offline libraries, the batch mode scans an entire playlist or channel page. You can select 50 videos simultaneously; Mpmux queues them, avoiding IP throttling via randomized delays.

Solution: This occurs if the audio stream was not captured. Go to extension settings → Mpmux tab → enable "Force audio stream detection." Also, avoid pausing the video during analysis.
