OGGからOGVへの変換について
OGG (audio) and OGV (video) both use the Ogg container format from Xiph.org. OGG typically contains Vorbis audio, while OGV contains Theora video with Vorbis audio. The underlying container is identical — only the file extension convention differs.
Converting OGG to OGV adds a video component (typically a static image encoded as Theora) alongside the existing Vorbis audio stream. The audio can be stream-copied since both formats use the same container.
OGGをOGVに変換する理由
Some platforms and systems specifically require the .ogv extension to identify video content. Wikimedia Commons and certain web CMS platforms distinguish between audio (.ogg) and video (.ogv) by extension. Converting OGG audio to OGV with a static image satisfies these requirements.
HTML5 video elements expect .ogv files rather than .ogg for video playback. Adding a video stream enables use in video contexts.
主な活用例
- Creating OGV files with audio content for Wikimedia Commons uploads
- Preparing OGG audio with a static image for HTML5 video elements
- Converting audio-only OGG to video-capable OGV for web platforms
- Building OGV presentations from OGG audio with slide images
- Meeting platform requirements that distinguish .ogg from .ogv
仕組み
FFmpeg can stream-copy the Vorbis audio from OGG to OGV (-c:a copy) since both use the Ogg container. A Theora video stream (from a static image) is added alongside the audio. The resulting OGV file contains both video and audio streams in the standard Ogg page structure.
品質とパフォーマンス
The Vorbis audio stream is copied without re-encoding — zero quality loss for the audio. The video stream quality depends on the Theora encoding settings for the static image. Overall audio fidelity is identical to the source OGG.
