Module mpeg2 

Minimal MPEG-1/2 video probing.

Siglus titles sometimes ship MPEG-PS/MPEG-2 video alongside OMV. For now we only implement lightweight parsing of the sequence header (0x000001B3) to retrieve dimensions and frame-rate code.

Structs

MpegSeqHeader

VideoFrameRgba

A decoded video frame in interleaved RGBA8.

Functions

decode_mpeg2_to_rgba_frames

ensure_mpeg_like

Convenience: validate that a file looks like MPEG by finding a sequence header.

find_sequence_header

fps_from_frame_rate_code

Convert MPEG frame_rate_code to nominal FPS.

probe_sequence_header

Scan the first max_scan_bytes bytes of a file for a MPEG sequence header.
