Sobre los archivos RMVBComparativa de ventajas
OGG Ventajas
- 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.
RMVB Ventajas
- Better quality-at-bitrate than fixed RealMedia.
- Still playable in modern open-source players (VLC, mpv).
- Cultural archive value for 2000s Asian internet video.
Limitaciones
OGG Limitaciones
- 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.
RMVB Limitaciones
- Tied to the dead RealNetworks ecosystem.
- H.264 is objectively better at equal bitrates.
- No modern encoder — content is archival only.
- Obscure format outside Asian regional archives.
