Android Video is a device-optimized preset producing H.264 MP4 files tuned for Android's MediaCodec hardware decoder. RMVB files use RealVideo codecs that Android does not support natively — there is no RealMedia decoder in Android's media framework. This conversion is essential for the millions of users in China and Southeast Asia who have RMVB movie collections and want to watch them on modern Android devices.
Android cannot play RMVB files without third-party apps like MX Player (which bundles its own RealVideo decoder). The Android Video preset produces native H.264/AAC MP4 files that play in any Android video app, support hardware-accelerated decoding for battery efficiency, and integrate with Android's media scanner for library organization.
FFmpeg decodes the RealVideo 8/9/10 stream and RealAudio track, then re-encodes to H.264 Main Profile Level 4.0 with CRF 23 for video and AAC-LC at 128 kbps for audio. Resolution is maintained at the RMVB source size (typically 640x480 to 1280x720) or scaled to 1920x1080 maximum. The MP4 container uses faststart for instant playback.
Quality is generally improved compared to the RMVB source — H.264 at CRF 23 often produces better visual results at similar file sizes. RMVB's RealVideo codec was efficient for its era but is significantly less capable than modern H.264. Expect noticeably clearer output, especially in motion scenes.

RMVB to Android Video conversion is the essential migration path for the enormous RMVB media libraries found across Asia. The output plays natively on every Android device while often improving visual quality over the original RMVB encoding.
