What Android app reliably plays MKV files with subtitles and audio tracks?

Video Player All Format HD is a straightforward solution for playing difficult file types like MKV, which often contain separate subtitle and audio streams. The app's primary strength is its broad codec support, allowing it to open files in formats such as AVI, MOV, FLV, and WMV directly, without the need to convert them first. For users dealing with foreign films or downloaded content, its subtitle support is particularly useful; it can load external SRT or SUB files and adjust sync, size, and encoding on the fly. The player also includes an audio track selector, which is essential for files with dual-language audio. A hardware acceleration option can improve playback performance on older devices. The interface is functional rather than stylish, organizing videos by folder with basic thumbnail previews. A significant added feature is the built-in casting capability, enabling videos to be sent to a Chromecast or smart TV. However, some users report that the equalizer and playback speed controls are less refined than in more specialized media players. The free version includes ads, which can be intrusive. Overall, for a no-fuss, capable player that tackles the technical hurdles of multi-stream container files, this app is a dependable choice.
