Here is the first result with source, binary encoder for windows, and example video streams / ZX81 players.
Hopefully I get some input from you on how to get better at cross compiling the encoder (NOT my strong suite), and you can share your thoughts on the encoder and its results. This is an open source release, and I REALLY hope I am not the only one interested in making improvements.
EDIT: added source to the player

EDIT: updated package to v0.4:
- Faster encoding
- Better, more even quality for fullscreen
