OGV uses Xiph.org's Theora video codec, which Amazon's Kindle Fire tablets cannot play. Kindle Fire runs Fire OS (Amazon's Android fork) with a media framework limited to standard Android codecs — H.264 and VP8 — excluding Theora. The Kindle Video preset produces MP4 with H.264 at parameters optimized for Kindle Fire's display and hardware decoder.
Kindle Fire tablets cannot decode Theora video. The built-in video player and Amazon's Silk browser reject OGV files entirely. Converting to the Kindle preset produces H.264 MP4 that plays natively on every Kindle Fire generation from the original (2011) through the latest models.
This conversion also optimizes resolution and bitrate for Kindle Fire's screen size (7-10 inches) and typically 16-32 GB storage capacity.
FFmpeg decodes Theora and Vorbis from the OGV, then transcodes to H.264 Baseline or Main Profile at Level 3.1 with AAC-LC audio. Resolution is scaled to 1280x800 (HD) or 1920x1200 (HDX) depending on the target Kindle model. Bitrate targets 2-4 Mbps for balanced quality and storage efficiency. The output MP4 uses faststart for instant playback.
Quality exceeds the original OGV at comparable file sizes because H.264 is far more efficient than Theora. On Kindle Fire's display, the converted video looks sharp and smooth. The resolution and bitrate are optimized for the screen's actual capability.
