mobipeg is a fork of FFmpeg with added support for encoding and decoding Nintendo MobiClip video formats. It uses a modified version of x264 for encoding and bundles a GUI tool for easy use.

Features

• Allows encoding and decoding Mobiclip videos for Wii, 3DS, and DS
• Allows ADPCM, FastAudio and PCM audio for Wii, 3DS, and DS (along with Vorbis for Wii)
• Allows encoding 3D video for 3DS
• Has a GUI for easy use to encode or decode videos, also can be used with CLI
• Works on Windows, Mac, and Linux - no Mobiclip SDK needed, and no license needed

mobiclip v1.1 released

• New format and codec support: Added encoders and decoders for VX (Actimagine/MobiclipDS video), RVID (Rocket Video), KWZ (Flipnote Studio 3D), PPM Flipnote, and THP (GameCube/Wii video). VX includes full CAVLC video codec, audio encoder/decoder, and both mux/demux.
• MODS improvements: Extended MODS encoder/decoder with broader audio support; Codebook (SX/FastAudio-SX) audio is now fully decodable (previously errored).
• ADPCM encoder: Major expansion of the ADPCM encoder (adpcmenc.c) with ~535 lines of new encoding logic.
• encode.py / encode_gui.py: Added YCgCo inverse colorspace correction (fixes green/magenta cast on MODS/VX decode), auto-detection of YCgCo sources via ffprobe, per-format demuxer forcing (PPM, KWZ, THP, RVID), duration/FPS probing, and MOBICLIP_KEYINT_MAX cap (90 frames, matching retail Wii .mo cadence).
• RVID tools: Added rvid.py, rvid_decode.py, and rvid_lz.c for standalone RVID unpacking with LZ compression

I tested this with replacing the Kirby Return to Dreamlands opening and it went smoothly!

There is some weird scaling issue but I think thats due to incorrect setting of Scale (I set it to 640x320, maybe I need to change it?)

I also tried doing the original cutscene by decoding and reencoding that, however that had another weird issue where the game hung at the end (metafortress? something else?) on top the incorrect scale

Overall though really great tool, and I wonder where this goes next!
