Melvra: MKV Video Player

No converting. No waiting. No stalling.

Melvra is a media player built only for iPhone and iPad. It opens the video sitting on your Mac, your PC, or your NAS without converting the file first. Instead of competing on the length of a format list, it is designed around two numbers you feel every single time: **how long it takes for the first frame to appear**, and **how long it takes to resume after you seek**.

PLAY IT AS IT IS
· MKV, AVI, WMV, FLV, WebM, TS, MPEG, MOV, MP4, RealMedia, and more
· A built-in FFmpeg-based engine (496 decoders, 354 demuxers)
· H.264, HEVC, and AV1 are handed to VideoToolbox still compressed, for hardware decoding. Only the codecs it cannot take are decoded in software
· Files are identified by what is inside them, not by the extension, so a mislabelled file still opens

SPEED YOU CAN SEE
· The Performance HUD shows codec, resolution, frame rate, whether hardware decoding is active, dropped frames, **measured open and seek times in milliseconds**, bitrate, buffer, and thermal state
· Keyframe positions are saved on first play, so opening and seeking the same file again is quicker

YOUR NAS, WITHOUT COPYING
· SMB (SMB2/3), WebDAV, and direct HTTP URLs
· Credentials are stored in the Keychain, and you can test a connection before you save it
· Read-ahead adapts to the throughput actually measured, and a seek cancels the read in flight so playback resumes from the new position

SUBTITLES AND AUDIO TRACKS
· ASS/SSA subtitles embedded in MKV are rendered by libass, with styles, positioning, and inline tags intact
· External subtitle files (SRT, WebVTT, ASS, SSA), with ±0.5 s timing adjustment and adjustable size
· Switch between multiple audio tracks without stopping playback — language, title, and codec are shown

RELIABLE OFFLINE
· Long-press a file on a server and choose Save Offline. If the transfer is interrupted, it resumes where it stopped
· Saved files are size-checked, and a downloaded copy is always played in preference to the network one

FILES ON YOUR DEVICE
· In-app Documents, shared with the Files app
· Add a USB-C SSD or another app's folder as an external folder and play from it in place, with no copying
· Open a video in Melvra straight from another app

STAYS COOL, SAVES BATTERY
· Battery Guardian watches the device's thermal state and eases bitrate and resolution when it heats up
· Choose Quality first, Auto, or Power saver

WHILE YOU WATCH
· Drag horizontally to seek, with a thumbnail preview; drag vertically on the left or right for brightness and volume
· Double-tap either side for ±10 seconds, press and hold for 2× speed
· 0.5× to 3.0× playback with pitch preserved, and A-B repeat
· Picture in Picture, background audio, and AirPlay
· Keyboard control on iPad (Space, arrow keys, J/K/L, Esc)

PICK UP WHERE YOU LEFT OFF
· Playback position is saved automatically, and one tap in Recents resumes it
