MiSTer Media Player
An experimental media-player core for MiSTer FPGA, with a standards-driven MPEG-2 Video / ITU-T H.262 decoder implemented primarily in FPGA logic.
Development status: active, pre-release, developer-oriented. v0.5.0 is the current published hardware-qualified milestone. It extends the progressive 4:2:0 I/P/B path to the 720x480 regression geometry and independently applies picture-signaled P/B motion-vector
f_codevalues from 1 through 4. Audio, program-stream demux, DVD support, and broader H.262 coverage remain future work.
Current status
The active decoder is a clean H.262 implementation under rtl/mpeg2_new/. It currently provides:
- streaming MPEG-2 elementary-stream input with FIFO backpressure;
- picture, slice, macroblock, block, and DCT VLC parsing for the supported paths;
- inverse quantization and fixed-point two-pass 8x8 IDCT;
- full 8-bit Y, Cb, and Cr intra reconstruction;
- two retained planar MiSTer DDR3 frame banks for I/P ping-pong/reference ownership plus a separate B scratch region;
- explicit DDR arbitration, DDR3 readback through small line caches, display-region write…
