j-gif

Screen recording to GIF for Python, implemented in Rust.

Frames are captured through Win32 GDI (BitBlt), compressed to JPEG and kept in a native frame store, then encoded to GIF -- all on native threads, so the GIL is never held during recording or export.

• FrameStore -- accepts BGRA/RGB frames, stores them JPEG-compressed, exports GIF
• FrameDecoder -- background decoding for playback over a bounded channel
• RecordSession -- recording state machine (recording / paused / stopped)

The distribution is j-gif; the module imports as gifrecorder.

import gifrecorder

store = gifrecorder.FrameStore(width, height, fps, jpeg_quality=90)
store.push_bgra(bgra_bytes, elapsed_ms)      # once per captured frame
store.export_gif("out.gif", repeat=0)
