Про конвертацію M4B у OGV
OGV is the video-oriented extension for OGG containers, typically containing Theora video and Vorbis audio. Converting M4B audiobooks to OGV creates an OGG file with Vorbis-encoded spoken-word audio using the .ogv extension. This is a highly specialized conversion for platforms that specifically require OGV media files — primarily Wikimedia Commons, certain academic platforms, and legacy HTML5 implementations.
Навіщо конвертувати M4B у OGV?
Wikimedia Commons accepts OGV for educational media uploads. Academic platforms with open-format mandates may require OGV. Creating OGV with a cover image as Theora video alongside Vorbis narration produces a 'video' that displays book cover art during audiobook playback — useful for web-based audiobook platforms using HTML5 video elements.
Типові сценарії використання
- Uploading audiobook excerpts to Wikimedia Commons as open-format media
- Creating audiobook 'videos' with cover art for web platforms using HTML5 video elements
- Supplying spoken-word content to academic platforms mandating OGV format

Як це працює
FFmpeg decodes the M4B's AAC audio and encodes as Vorbis inside an OGG container with .ogv extension. Optionally, a static cover image is encoded as a Theora video stream to create a proper video file. The OGG container is identical regardless of the .ogg or .ogv extension — only the expected content type differs.
Якість і продуктивність
Vorbis quality 2-3 (≈64-80 kbps) provides excellent spoken-word quality. The OGV container has zero impact on audio quality.
