About OGG filesStrengths Comparison
MKV Strengths
- Carries virtually any codec — H.264, H.265, AV1, VP9, Opus, FLAC, AAC, you name it.
- Multiple audio and subtitle tracks, chapters, and menus in one file.
- Patent-free container — no licensing fees.
- Attached fonts and metadata ride along for self-contained playback.
- Streamable and seekable with built-in index/cue tables.
OGG Strengths
- Completely royalty-free — no patent worries for encoders or decoders.
- Container is streaming-friendly — useful for internet radio.
- Native support in HTML5 <audio>, every major Linux distro, and most audio tools.
- Can multiplex any number of tracks (audio, video, text) in one file.
- Mature tooling via libvorbis, libopus, and FFmpeg.
Limitations
MKV Limitations
- Not natively supported in Apple's QuickTime or Safari without third-party tools.
- Windows needed codec packs (or "Films & TV" app updates) to play it out of the box.
- Hardware decoders on older TVs and streamers often reject MKV.
- Because it allows any codec, compatibility varies wildly by player.
OGG Limitations
- Apple and Microsoft avoided Ogg historically — iOS and Safari only added Opus support recently.
- Hardware decoder support is rare — encoding for battery-constrained devices (phones) still favors AAC.
- Confusing naming: ".ogg" could be Vorbis, Opus, Speex, or FLAC.
- Metadata conventions (Vorbis comments) are simpler than MP4's tagging.
