    FFmpeg参数介绍

    ffmpeg -re -rtsp_transport tcp -i "rtsp://admin:a12345678@10.16.55.150:555//Streaming/Channels/1" -f flv -vcodec libx264 -vprofile baseline -acodec aac -ar 44100 -strict -2 -ac 1 -f flv -flvflags no_duration_filesize  -r 29.97 -s 1280x720 -q 10 "rtmp://localhost:1935/live/1"
    
    • re:按照时间戳顺序推流 不加的话直接把所有文件都推过去
    • rtsp_transport tcp:强制使用TCP方式读取rtsp流
    • codec copy:从输入文件中进行拷贝
    • acodec aac 设定声音编码
    • acodec codec 使用codec编解码
    • i后面是摄像头流地址,flv后面是推到nginx机器的地址
    • vcodec libx264:使用H.264的编码格式
    • vcodec libx264 -acodec libfaac:同时保存音视频数据
    • ac: <数值> 设定声道数,1就是单声道,2就是立体声,转换单声道的TVrip可以用1(节省一半容量),高品质
      的DVDrip就可以用2
    • r 29.97(帧数,一般就用这个吧)
    • s :分辨率
    • ar <采样率> 设定声音采样率,PSP只认24000
    • ab <比特率> 设定声音比特率,前面-ac设为立体声时要以一半比特率来设置,比如192kbps的就设成96,转换君默认比特率都较小,要听到较高品质声音的话建议设到160kbps(80)以上
    • flvflags no_duration_filesize:这个参数是关键,这个参数告诉ffmpeg不要抛出duration_filesize警告
    • q:v 图像质量, 2为保存为高质量
    • strict -2:使用FFmpeg自带的aac音频编码要带上-strict -2 参数就可以了。带这个参数是为了使用aac音频编码。
    • strict experimental :解锁实验项目所必须
    • vcodec 视讯编解码器 等同: -coddec:a, -c:v 视讯编码器
    • acodec 音讯编解码器 等同: -coddec:a, -c:a 音讯编码器
    • scodec 字幕编解码器 等同: -coddec:s, -c:s 字幕编码器

    将音频文件(m4s)和视频文件(m4s)通过ffmpeg合成在一起:

    ffmpeg -i C:\Users\Administrator\Desktop\88916243\c_151886907\16\video.m4s -i C:\Users\Administrator\Desktop\88916243\c_151886907\16\audio.m4s -c:v copy -strict experimental C:\Users\Administrator\Desktop\88916243\c_151886907\16\output1.mp4

    蓝色加粗的部分是在ffmpeg下键入的命令,黑色的是系统打印的命令。只要命令和视频流正确,那么是一定可以播放的。虽然视频播放的时候没有显示出进度条,但是在左右点击屏幕的时候,会产生点击进度条的效果。

    一、系统打印命令解析

    在此命令执行过程中,我们可以看到如下数据:

    1、ffmpeg在运行过程中需要用到的lib库如下

      libavutil      52. 47.101 / 52. 47.101

      libavcodec     55. 37.102 / 55. 37.102

      libavformat    55. 19.103 / 55. 19.103

      libavdevice    55.  4.100 / 55.  4.100

      libavfilter     3. 88.102 /  3. 88.102

      libswscale      2.  5.101 /  2.  5.101

      libswresample   0. 17.104 /  0. 17.104

      libpostproc    52.  3.100 / 52.  3.100

    2、Input #0, hls,applehttp, from 'http://172.30.25.246:9090/mpeg/wd/vodtest/FLAT_TE

    ST06.m3u8':

    其中介绍的是片源的信息,hls为传输协议(是苹果的),后面的网址是视频的来源。

    3、Duration: 00:01:30.00, start: 51210.426000, bitrate: 0 kb/s

    Duration为时长,可以看见正在播放的片源为1分30秒。Start后面代表的是视频片内的偏移地址,bitrate为码率。

    4、Metadata:

          variant_bitrate : 0

        Stream #0:0: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p, 720x576 [

    SAR 17:12 DAR 85:48], 25 fps, 25 tbr, 90k tbn, 50 tbc

        Stream #0:1: Audio: aac ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 51

     kb/s

    Metadata为元数据,就是描述其他数据的数据,相当于数据库里面的字段。

    Stream #0:0: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p, 720x576 [SAR 17:12 DAR 85:48], 25 fps, 25 tbr, 90k tbn, 50 tbc

    第0:0个流是视频流,编码为h264,颜色编码为yuv420p,分辨率为720x576, 25帧每秒,帧率为25,文件层的时间精度为1S=90k,视频层的时间精度为1S=50

     

    Stream #0:1: Audio: aac ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 51 kb/s

    第0:1个流是音频流,采用的是aac(高级编码)技术,采样频率为48000Hz;立体声;AV_SAMPLE_FMT_FLTP格式的数据,码率为51kb/s。

    二、关键词介绍

    HLS介绍HLS,Http Live Streaming 是由Apple公司定义的用于实时流传输的协议,HLS基于HTTP协议实现,传输内容包括两部分,一是M3U8描述文件,二是TS媒体文件。

     

    YUV是一种颜色编码方法(属于PAL)主要用于优化彩色视频信号的传输,使其向后相容老式黑白电视。与RGB视频信号传输相比,它最大的优点在于只需占用极少的频宽(RGB要求三个独立的视频信号同时传输)。采用YUV色彩空间的重要性是它的亮度信号Y和色度信号U、V是分离的。如果只有Y信号分量而没有U、V分量,那么这样表示的图像就是黑白灰度图像

     

    PAR - pixel aspect ratio(可以理解为单个像素的宽高比)大多数情况为1:1,就是一个正方形像素,否则为长方形像素。常用的PAR比率(1:1,10:11, 40:33, 16:11, 12:11 ).

    DAR - display aspect ratio就是视频播放时,我们看到的图像宽高的比例,缩放视频也要按这个比例来,否则会使图像看起来被压扁或者拉长了似的。

    SAR - storage aspect ratio就是对图像采集时,横向采集与纵向采集构成的点阵,横向点数与纵向点数的比值。比如VGA图像640/480 = 4:3,D-1 PAL图像720/576 = 5:4

    这三者的关系PAR x SAR = DAR或者PAR = DAR/SAR.

     

    tbr代表帧率,tbn代表文件层的时间精度,和duration相关;tbc代表视频层的时间精度和时间戳相关。

     

    AAC(Advanced Audio Coding),中文名:高级音频编码,出现于1997年,基于MPEG-2的音频编码技术。一种专为声音数据设计的文件压缩格式,与Mp3不同,它采用了全新的算法进行编码,更加高效,具有更高的“性价比”。利用AAC格式,可使人感觉声音质量没有明显降低的前提下,更加小巧。fltp:AV_SAMPLE_FMT_FLTP格式的数据( float, 4bit , planar);码率越高,文件所含的信息量就越大,音质就越高。

    ffplay基本参数

    在这里插入图片描述
    下面列举几个例子
      如果希望从视频的第30秒开始播放,播放10秒钟的文件,则可以使用如下命令;

    ffplay -ss 30 -t 10 inuput.mp4

      如果希望视频播放时播放器的窗口显示标题为自定义标签则可以使用如下命令;

    ffplay -window_tiltle “Hello world” inuput.mp4

    上述命令返回如下

    在这里插入图片描述

    ffpaly高级参数

    在这里插入图片描述
    下面将这些参数与=前面的参数进行组合,列举几个例子。
      例如从20秒播放一个视频,视频时长为10秒,播放完成后自动退出ffplay,播放的窗口标题为hello word ,为了确认播放时长正确,可以通过系统命令time查看命令运行时长:

    time ffplay -window_title "hello word : -ss 20 -t 10 -autoexit inuput.mp4

    该命令执行完毕输出如下


    real         0m10.783s
    user       0m8.401s
    sys      0m0.915s


      从输出的内容分析来看,实际消耗时间为10.783秒,用户框架为8.401秒。情况基本相符。

      例如强制使用H.264解码器解码MPEG4的视频将会报错:

    ffplay -vcodec h264 inuput.mp4

    在这里插入图片描述
      从输出的信息可以看到,使用h264的解码器MPEG4时会得到no frame的错误,视频也解析不出了

      前面举过的例子中,我们可以看到的比价多的是单节目的流,下面列举一个多节目的流,常见于广店行业的视频;
      当视频流中出现多个program时,播放program与常规的播放方式有所不同,需要指定对应的流,可以通过vst,ast,sst参数来指定,例如希望播放program13中的音视频流,视频流编号为4.音频流编号为5,则可以通过如下命令进行指定

    ffplay -vst 4 -ast 5 ~/Movies/movie/ChinaTV-11.ts

      如果使用ffplay播放视频时希望加载字幕文件,则可以通过加载ASS或者SRT字幕文件来解决,下面列举一个加载字幕的例子,首先编辑SRT字幕文件,内容如下:

    在这里插入图片描述
      然后通过filter将字幕文件加载到播放数据中,使用命令如下:

    ffplay -window_title “Test Movie” -vf “subtitles=inuput.srt” inuput.mp4

    播放效果如下
    在这里插入图片描述
     &nbsp**;ffplay的数据可视化分析应用**
      使用ffplay除了可以播放视频流媒体文件之外,还可以作为可视化的视频流媒体分析工具,例如播放音频文件时,如果不确定文件的声音是否正常,则可以使用ffplay播放音频文件,播放的时候其将会把解码后的音频数据以音频波形的形式显示出来,命令执行后的效果如下:

    ffplay -showmode 1 intput.mp3

    在这里插入图片描述

    例如,当播放视频是想要体验解码器是如何解码每个宏块的,可以使用以下命令;

    ffplay -debug vis_mb_type -window_title “show vis_mb_type” -ss 20 -t 10 -autoexit inuput.mp4

    播放效果如下:
    在这里插入图片描述

      

    在输出视频信息中,可以看到不同颜色的方块。下面就来说一下这些颜色分别代表什么信息,具体见表2-10(见彩插) 宏块颜色说明:

    在这里插入图片描述
      例如通过ffplay查看B帧预测与P帧预测信息,希望将信息在窗口中显示出来,可使用如下命令;

    ffplay -vismv pf inuput.mp4

    播放效果如下:

    在这里插入图片描述
      根据上图的箭头可以看到P帧运动估计的信息,而vismv参数则是用来显示图像解码时的运动向量信息的,可以数字三种类型的运动向量显示,
    运动向量显示参数:
    在这里插入图片描述
    这个vismv参数将会在未来被替换掉,未来更多的是使用codecview这个滤镜来进行设置,如下

    ffplay -flafs2 +export_mvs -ss 40 inuput.mp4 -vf codecview=mv=pf+bf+bb
