readframe.asv

用matlab写的仿真H.263标准的程序

function [FrameY,FrameU,FrameV] = ReadFrame(fid,format)
%从读取一帧


switch format
    case 'cif'
        [FrameY,count] = fread(fid, [288,352], 'uint8');
        [FrameU(:,:),count] = fread(fid, [144,176], 'uint8');
        FrameV(:,:) = fread(fid, [144,176], 'uint8');
    case 'pal'
        FrameY(:,:) = fread(fid, [576,720], 'uint8');
        FrameU(:,:) = fread(fid, [288,360], 'uint8');
        FrameV(:,:) = fread(fid, [288,360], 'uint8'');
    otherwise
        disp('error format');
end
