Giới thiệu về chuyển đổi RM sang OGV
OGV (Ogg Video) is the Xiph.org Foundation's open-source video container, pairing Theora video codec with Vorbis audio. Theora descended from On2 Technologies' VP3 codec — the same lineage that led to VP8 and VP9 used in WebM. OGV was once the leading candidate for HTML5 video before MP4 and WebM won broader support. RM (RealMedia) was RealNetworks' 1997 streaming format using proprietary RealVideo codecs (RV10, RV20) with constant bitrate encoding for dial-up modems.
Converting RM to OGV moves content from one era of web video to another — from proprietary RealPlayer streaming to open-source, patent-free web video. While OGV has been largely superseded by WebM in modern web usage, it remains relevant for open-source projects, Wikimedia Commons, and environments that mandate patent-free formats.
Tại sao nên chuyển đổi RM sang OGV?
RM is proprietary and dead. OGV is open-source and patent-free. For organizations and projects committed to open standards — Wikipedia, open-access educational repositories, GNU/Linux distributions, government agencies with open-format mandates — OGV provides a video format with no licensing or patent encumbrances.
OGV also plays in Firefox, Chrome, and some other browsers via the HTML5 video element, though support is less universal than MP4 or WebM. Converting RM to OGV is primarily about principle (open standards) rather than practicality (maximum compatibility). For pure reach, MP4 or WebM are better choices.
