What's the best iOS app for playing video and audio files that other apps can't handle?

VLC media player is a versatile and reliable media playback application for iOS that tackles the common issue of incompatible file formats. It stands out by supporting an extensive list of video and audio codecs, from standard MP4 and MP3 to niche formats like MKV, FLAC, and OGG, which often fail to play in default iOS apps. This makes it indispensable for users with diverse media libraries, such as those who download content from various sources or have archived files from older devices. A significant feature is its network streaming capability, enabling seamless playback of files stored on computers, NAS drives, or cloud services via Wi-Fi—ideal for accessing large collections without filling iPhone storage. The built-in equalizer allows audio fine-tuning, with user tips suggesting pre-amp boosts for quieter tracks. Accessibility is robust, with full VoiceOver compatibility praised by visually impaired users. Reviews indicate that the app can be finicky occasionally, particularly with interface navigation or when managing complex playlists, but these are minor compared to its strengths. For real-world scenarios, it serves well for playing local music, streaming home videos, or even cueing tracks in live performances, as noted by theater technicians. While not without its quirks, VLC's free, open-source model and consistent updates make it a go-to solution for format flexibility and cross-platform media management.
