I帧/P帧/B帧</h2><p><strong>I帧</strong>：I帧(Intra-coded picture, 帧内编码帧，常称为关键帧)包含一幅完整的图像信息，属于帧内编码图像，不含运动矢量，在解码时不需要参考其他帧图像。因此在I帧图像处可以切换频道，而不会导致图像丢失或无法解码。I帧图像用于阻止误差的累积和扩散。在闭合式GOP中，每个GOP的第一个帧一定是I帧，且当前GOP的数据不会参考前后GOP的数据。</p><p><strong>P帧</strong>：P帧(Predictive-coded picture, 预测编码图像帧)是帧间编码帧，利用之前的I帧或P帧进行预测编码。</p><p><strong>B帧</strong>：B帧(Bi-directionally predicted picture, 双向预测编码图像帧)是帧间编码帧，利用之前和(或)之后的I帧或P帧进行双向预测编码。B帧不可以作为参考帧。
|
|
B帧具有更高的压缩率，但需要更多的缓冲时间以及更高的CPU占用率，因此B帧适合本地存储以及<a data-text-link="49_1409507" data-from="10680" href="https://cloud.tencent.com/product/vod?from=10680" target="_blank">视频点播</a>，而不适用对实时性要求较高的直播系统。</p><h2 id="2.-DTS%E5%92%8CPTS" name="2.-DTS%E5%92%8CPTS">2. DTS和PTS</h2><p>DTS(Decoding Time Stamp, 解码时间戳)，表示压缩帧的解码时间。
|
|
PTS(Presentation Time Stamp, 显示时间戳)，表示将压缩帧解码后得到的原始帧的显示时间。
|
|
音频中DTS和PTS是相同的。视频中由于B帧需要双向预测，B帧依赖于其前和其后的帧，因此含B帧的视频解码顺序与显示顺序不同，即DTS与PTS不同。当然，不含B帧的视频，其DTS和PTS是相同的。下图以一个开放式GOP示意图为例，说明视频流的解码顺序和显示顺序

|
<strong>采集顺序</strong>指图像传感器采集原始信号得到图像帧的顺序。
|
|
<strong>编码顺序</strong>指编码器编码后图像帧的顺序。存储到磁盘的本地视频文件中图像帧的顺序与编码顺序相同。
|
|
<strong>传输顺序</strong>指编码后的流在网络中传输过程中图像帧的顺序。
|
|
<strong>解码顺序</strong>指解码器解码图像帧的顺序。
|
|
<strong>显示顺序</strong>指图像帧在显示器上显示的顺序。
|
|
<strong>采集顺序与显示顺序相同。编码顺序、传输顺序和解码顺序相同。</strong>
|

以图中“B[1]”帧为例进行说明，“B[1]”帧解码时需要参考“I[0]”帧和“P[3]”帧，因此“P[3]”帧必须比“B[1]”帧先解码。这就导致了解码顺序和显示顺序的不一致，后显示的帧需要先解码。</p><h2 id="3.-FFmpeg%E4%B8%AD%E7%9A%84%E6%97%B6%E9%97%B4%E5%9F%BA%E4%B8%8E%E6%97%B6%E9%97%B4%E6%88%B3" name="3.-FFmpeg%E4%B8%AD%E7%9A%84%E6%97%B6%E9%97%B4%E5%9F%BA%E4%B8%8E%E6%97%B6%E9%97%B4%E6%88%B3">3.

|
|
FFmepg中有三种时间基，命令行中tbr、tbn和tbc的打印值就是这三种时间基的倒数：
|
|
tbn：对应容器中的时间基。值是AVStream.time_base的倒数
|
|
tbc：对应编解码器中的时间基。值是AVCodecContext.time_base的倒数
|
|
tbr：从视频流中猜算得到，可能是帧率或场率(帧率的2倍)</p><p>测试文件下载：<a data-from="10680" href="https://github.com/leichn/blog_resources/blob/master/video/tuan/tnmil3.flv" target="_blank" rel="nofollow noopener noreferrer">tnmil3.flv</a>

The
|
|
values printed are actually reciprocals of these, i.e. 1/tbr, 1/tbn and
|
|
1/tbc.
|
|
tbn is the time base in AVStream that has come from the container, I
|
|
think. It is used for all AVStream time stamps.
|
|
tbc is the time base in AVCodecContext for the codec used for a
|
|
particular stream. It is used for all AVCodecContext and related time
|
|
stamps.
|
|
tbr is guessed from the video stream and is the value users want to see
|
|
when they look for the video frame rate, except sometimes it is twice
|
|
what one would expect because of field rate versus frame rate.

|
|
* This is the fundamental unit of time (in seconds) in terms
|
|
* of which frame timestamps are represented. For fixed-fps content,
|
|
* timebase should be 1/framerate and timestamp increments should be
|
|
* identically 1.
|
|
* This often, but not always is the inverse of the frame rate or field rate
|
|
* for video. 1/time_base is not the average frame rate if the frame rate is not
|
|
* constant.
|
|
*
|
|
* Like containers, elementary streams also can store timestamps, 1/time_base
|
|
* is the unit in which these timestamps are specified.
|
|
* As example of such codec time base see ISO/IEC 14496-2:2001(E)
|
|
* vop_time_increment_resolution and fixed_vop_rate
|
|
* (fixed_vop_rate == 0 implies that it is different from the framerate)
|
|
*
|
|
* - encoding: MUST be set by user.
|
|
* - decoding: the use of this field for decoding is deprecated.
|
|
* Use framerate instead.

这里有一个问题：按照此处注释说明，帧率为25的视频流，tbc理应为25，但实际值却为50，不知作何解释？是否tbc已经过时，不具参考意义？</p><p>根据注释中的建议，实际使用时，在视频解码过程中，我们不使用AVCodecContext.time_base，而用帧率倒数作时间基，在视频编码过程中，我们将AVCodecContext.time_base设置为帧率的倒数。</p><h4 id="3.7.1-%E8%A7%86%E9%A2%91%E6%B5%81" name="3.7.1-%E8%A7%86%E9%A2%91%E6%B5%81">3.7.1 视频流</h4><p>视频按帧播放，所以解码后的原始视频帧时间基为 1/framerate。

I帧\u002FP帧\u002FB帧\nI帧：I帧(Intra-coded picture, 帧内编码帧，常称为关键帧)包含一幅完整的图像信息，属于帧内编码图像，不含运动矢量，在解码时不需要参考其他帧图像。因此在I帧图像处可以切换频道，而不会导致图像丢失或无法解码。I帧图像用于阻止误差的累积和扩散。在闭合式GOP中，每个GOP的第一个帧一定是I帧，且当前GOP的数据不会参考前后GOP的数据。\nP帧：P帧(Predictive-coded picture, 预测编码图像帧)是帧间编码帧，利用之前的I帧或P帧进行预测编码。\nB帧：B帧(Bi-directionally predicted picture, 双向预测编码图像帧)是帧间编码帧，利用之前和(或)之后的I帧或P帧进行双向预测编码。B帧不可以作为参考帧。\n B帧具有更高的压缩率，但需要更多的缓冲时间以及更高的CPU占用率，因此B帧适合本地存储以及视频点播，而不适用对实时性要求较高的直播系统。\n2. DTS和PTS\nDTS(Decoding Time Stamp, 解码时间戳)，表示压缩帧的解码时间。\n PTS(Presentation Time Stamp, 显示时间戳)，表示将压缩帧解码后得到的原始帧的显示时间。\n 音频中DTS和PTS是相同的。视频中由于B帧需要双向预测，B帧依赖于其前和其后的帧，因此含B帧的视频解码顺序与显示顺序不同，即DTS与PTS不同。当然，不含B帧的视频，其DTS和PTS是相同的。下图以一个开放式GOP示意图为例，说明视频流的解码顺序和显示顺序\n \n?\n\n 采集顺序指图像传感器采集原始信号得到图像帧的顺序。\n 编码顺序指编码器编码后图像帧的顺序。存储到磁盘的本地视频文件中图像帧的顺序与编码顺序相同。\n 传输顺序指编码后的流在网络中传输过程中图像帧的顺序。\n 解码顺序指解码器解码图像帧的顺序。\n 显示顺序指图像帧在显示器上显示的顺序。\n 采集顺序与显示顺序相同。编码顺序、传输顺序和解码顺序相同。\n 以图中“B[1]”帧为例进行说明，“B[1]”帧解码时需要参考“I[0]”帧和“P[3]”帧，因此“P[3]”帧必须比“B[1]”帧先解码。这就导致了解码顺序和显示顺序的不一致，后显示的帧需要先解码。\n3. FFmpeg中的时间基与时间戳\n3.1 时间基与时间戳的概念\n在FFmpeg中，时间基(time_base)是时间戳(timestamp)的单位，时间戳值乘以时间基，可以得到实际的时刻值(以秒等为单位)。例如，如果一个视频帧的dts是40，pts是160，其time_base是1\u002F1000，那么可以计算出此视频帧的解码时刻是40毫秒(40\u002F1000)，显示时刻是160毫秒(160\u002F1000)。FFmpeg中时间戳(pts\u002Fdts)的类型是int64_t类型，把一个time_base看作一个时钟脉冲，则可把dts\u002Fpts看作时钟脉冲的计数。\n3.2 三种时间基tbr、tbn和tbc\n不同的封装格式具有不同的时间基。在FFmpeg处理音视频过程中的不同阶段，也会采用不同的时间基。\n FFmepg中有三种时间基，命令行中tbr、tbn和tbc的打印值就是这三种时间基的倒数：\n tbn：对应容器中的时间基。值是AVStream.time_base的倒数\n tbc：对应编解码器中的时间基。值是AVCodecContext.time_base的倒数\n tbr：从视频流中猜算得到，可能是帧率或场率(帧率的2倍)\n测试文件下载：tnmil3.flv\n 使用ffprobe探测媒体文件格式，如下：\nthink@opensuse\u003E ffprobe tnmil3.flv \nffprobe version 4.1 Copyright (c) 2007-2018 the FFmpeg developers\nInput #0, flv, from 'tnmil3.flv':\n Metadata:\n encoder : Lavf58.20.100\n Duration: 00:00:03.60, start: 0.017000, bitrate: 513 kb\u002Fs\n Stream #0:0: Video: h264 (High), yuv420p(progressive), 784x480, 25 fps, 25 tbr, 1k tbn, 50 tbc\n Stream #0:1: Audio: aac (LC), 44100 Hz, stereo, fltp, 128 kb\u002Fs\n关于tbr、tbn和tbc的说明，原文如下，来自FFmpeg邮件列表：\n There are three different time bases for time stamps in FFmpeg. The\n values printed are actually reciprocals of these, i.e. 1\u002Ftbr, 1\u002Ftbn and\n 1\u002Ftbc.\n tbn is the time base in AVStream that has come from the container, I\n think. It is used for all AVStream time stamps.\n tbc is the time base in AVCodecContext for the codec used for a\n particular stream. It is used for all AVCodecContext and related time\n stamps.\n tbr is guessed from the video stream and is the value users want to see\n when they look for the video frame rate, except sometimes it is twice\n what one would expect because of field rate versus frame rate.\n \n3.3 内部时间基AV_TIME_BASE\n除以上三种时间基外，FFmpeg还有一个内部时间基AV_TIME_BASE(以及分数形式的AV_TIME_BASE_Q)\n\u002F\u002F Internal time base represented as integer\n#define AV_TIME_BASE 1000000\n\n\u002F\u002F Internal time base represented as fractional value\n#define AV_TIME_BASE_Q (AVRational){1, AV_TIME_BASE}\nAV_TIME_BASE及AV_TIME_BASE_Q用于FFmpeg内部函数处理，使用此时间基计算得到时间值表示的是微秒。\n3.4 时间值形式转换\nav_q2d()将时间从AVRational形式转换为double形式。AVRational是分数类型，double是双精度浮点数类型，转换的结果单位是秒。转换前后的值基于同一时间基，仅仅是数值的表现形式不同而已。\nqv_q2d()实现如下：\n\u002F**\n * Convert an AVRational to a `double`.\n * @param a AVRational to convert\n * @return `a` in floating-point form\n * @see av_d2q()\n *\u002F\nstatic inline double av_q2d(AVRational a){\n return a.num \u002F (double) a.den;\n}\nqv_q2d()使用方法如下：\n时刻值：timestamp(单位秒) = pts × av_q2d(stream-\u003Etime_base);\n时长值：duration(单位秒) = stream-\u003Eduration × av_q2d(stream-\u003Etime_base);\n3.5 时间基转换函数\nav_rescale_q()用于不同时间基的转换，用于将时间值从一种时间基转换为另一种时间基。\n\u002F**\n * Rescale a 64-bit integer by 2 rational numbers.\n *\n * The operation is mathematically equivalent to `a × bq \u002F cq`.\n *\n * This function is equivalent to av_rescale_q_rnd() with #AV_ROUND_NEAR_INF.\n *\n * @see av_rescale(), av_rescale_rnd(), av_rescale_q_rnd()\n *\u002F\nint64_t av_rescale_q(int64_t a, AVRational bq, AVRational cq) av_const;\nav_packet_rescale_ts()用于将AVPacket中各种时间值从一种时间基转换为另一种时间基。\n\u002F**\n * Convert valid timing fields (timestamps \u002F durations) in a packet from one\n * timebase to another.
