The parameters allowed now are as follows:最近修改的解码器格式，使更高的灵活性和基本类似编码器的格式。现在允许的参数如下：7.2.1 InputFile(输入文件)Class（类型）: Text（文本） Description（说明）: Input bitstream file name. Name could include file path(输入的比特流文件的名称。名称可以包括文件的路径). Note（注意）: For Unix/Linux based systems directories should be separated using a backslash “”, while for DOSWindows systems, directories should be separated using a forward slash “/”（ 对于Unix / Linux为基础的系统目录应分开使用反斜杠“”，同时为DOS Windows系统目录应使用一个正斜杠“/”分隔。）.Example 1 (DOS):ldecod.exe -p InputFile=f:seq420176x144foreman_176x144_30.264Example 2 (Unix/Linux):ldecod.exe -p InputFile=/vol/seq/420/176x144/foreman_176x144_30.2647.2.2 OutputFile（输出文件）Class（类型）: Text（文本） Description（说明）: Decoder output filename. The output will be a raw video file in either YUV or RGB format（解码器输出的文件名。输出将是一个在任YUV或RGB格式的原始视频文件）.7.2.3 RefFileClass（类型）: Text（文本） Description（说明）: Reference input file for distortion (PSNR) computations（参考失真（PSNR），计算的输入文件）.7.2.4 WriteUV Class（类型）: Boolean（布尔值） Description: Write 4:2:0 chroma components for monochrome streams（4：2：0色度分量的单色流）7.2.5 FileFormat Class（类型）: Boolean （布尔值）Description: Input file format (0=Annex B, 1: RTP packets)（输入文件的格式（0 =附件B，1：RTP包）7.2.6 RefOffset Class: Numeric (Integer)（数值（整数） Description: PSNR computation offset(PSNR的计算偏移)7.2.7 POCScale Class: Numeric (Integer) （数值（整数）Description: Poc Scale (1 or 2) to be utilized for PSNR computations(PSNR的计算被用于POC量表（1或2）)7.2.8 DisplayDecParams Class: Boolean （布尔值）Description: Display decoder configuration parameters(显示解码器配置参数).7.2.9 ConcealMode Class: Numeric (Integer) （数值（整数）Description: Perform Error Concealment(执行错误隐藏)option0Disabled (default)(禁用（默认）)1Frame Copy method (帧复制方法)2Motion Copy method(运动Copy方法)7.2.10 RefPOCGap Class: Numeric (Integer) （数值（整数）Description: Reference POC gap (2: IPP (Default), 4: IbP / IpP)( 参考POC的差距（2：IPP（默认），4：IBP/ IPP）)7.2.11 POCGap Class: Numeric (Integer) （数值（整数） Description: POC gap (2: IPP /IbP/IpP (Default), 4: IPP with frame skip = 1 etc.)( POC的差距（2：IPP/ IBP/ IPP（默认），4：帧跳过=1等IPP）)7.2.12 Silent Class: Boolean （布尔值）Description: Perform silent decoding(执行无声的解码)7.2.13 IntraProfileDeblocking Class: Boolean （布尔值）Description: Enable Deblocking filter in intra only profiles (0=disable, 1=filter according to SPS parameters). This method essentially works as a post-process(在内部唯一的配置文件中启用消除马赛克的滤镜（0 =禁用，1=过滤器根据SPS的参数）。这种方法实质上是后处理工作).7.2.14 DecFrmNum Class: Numeric (Integer) （数值（整数）Description: Number of frames to be decoded (-n)( 被解码的帧数（- N）)7.2.15 DecodeAllLayers Class: Boolean Description: Enables decoding of all layers for MVC. This is equivalent to mpr.7.3 Decoder Output When running the decoder, the decoder will display on screen rate/distortion statistics for every frame coded. Cumulative results will also be presented. The output information generated may look as follows:- JM 17.1 (FRExt) - Decoder config file : decoder.cfg - Input H.264 bitstream : test.264 Output decoded YUV : test_dec.yuv Output status file : log.dec Input reference file : test_rec.yuv - POC must = frame# or field# for SNRs to be correct - Frame POC Pic# QP SnrY SnrU SnrV Y:U:V Time(ms) - 00000(IDR) 0 0 28 0.0000 0.0000 0.0000 4:2:0 16 00006( P ) 12 1 28 0.0000 0.0000 0.0000 4:2:0 0 00004( b ) 8 2 28 0.0000 0.0000 0.0000 4:2:0 15 00002( b ) 4 3 28 0.0000 0.0000 0.0000 4:2:0 16 - Average SNR all frames - SNR
