QuickTime Player vs SMPlayer

QuickTime Player is Apple’s free player for video and audio files on macOS. It supports MOV, H.264, HEVC, MPEG-4 audio, and AAC, along with network playback, subtitles, hardware acceleration, and 4K playback. Controls include play, pause, rewind, fast-forward, and speed settings from 2x through 60x, with smaller steps between 1.1x and 2x. Files can play through AirPlay or in a picture-in-picture window. QuickTime Player trims, rearranges, rotates, and splits movies, records the whole Mac screen or a selected area, and captures connected iPhone, iPad, or iPod touch screens. Camera recording can use built-in or external hardware. Movie exports are.mov using H.264 or HEVC; audio-only exports use MPEG4 audio, and MP4 video export is not available. Export resolutions include 4K, 1080p, 720p, 480p, and Audio Only, subject to the source. It is included with macOS at free.

SMPlayer is a free media player for Windows, Linux, and macOS. It includes built-in codecs to play most audio and video formats without requiring external codecs. Listed formats include AVI, ASF/WMV/WMA, QT/MOV/MP4, RealAudio/RealVideo, Ogg/OGM, Matroska, MPEG-1/2, H.264, MPEG-4, MP3, AAC, AC3, and DTS. The player supports network playback, subtitles, hardware acceleration, and 4K playback. It provides a graphical interface for MPlayer and can also use mpv as its playback engine. SMPlayer remembers playback position and settings such as audio track, subtitles, and volume. Controls include playback speed adjustment, audio and video filters, audio and subtitle delay adjustment, and a video equalizer. It can play YouTube videos, search for subtitles through OpenSubtitles, and send local videos or online streams to Chromecast devices. The project is free and open source under the GPL, offers source code, and directs users to a forum for help and a bug tracker for reporting problems.
