音视频封装demo：将h264数据和aac数据封装(mux)成TS文件(纯手工，不依赖第三方开源库)

1、README

a. demo使用

$ make clean && make DEBUG=1
$
$ ./ts_mux_h264_aac
Usage:
   ./ts_mux_h264_aac avfile/test1_856x480_24fps.h264 24 avfile/test1_44100_stereo.aac out1.ts
   ./ts_mux_h264_aac avfile/test2_720x480_30fps.h264 60 avfile/test2_48000_stereo.aac out2.ts
   ./ts_mux_h264_aac avfile/test3_1280x720_20fps.h264 20 avfile/test1_44100_stereo.aac out3.ts

（注：目前合成的out1.ts在使用potPlayer播放时进度条有点问题，待修复。）

目前合成视频的现象：

（out2.ts含有除SPS、PPS、IDR、PSLICE以外的其他NALU，所以主要看out1.ts和out3.ts）

• out1.ts：
  • 电影和电视、ACG播放器
    • 播放不流畅（含有B帧，而程序只填pts没填dts导致，对比out3.ts可知，无关紧要）；
    • 正常播放进度条时长正常（29s），拖动后有声音但画面卡住一会才动、音视频同步；
  • VLC
    • 播放不流畅（含有B帧，而程序只填pts没填dts导致，对比out3.ts可知，无关紧要）；
    • 正常播放进度条时长正常（29s），拖动后有声音但画面会灰屏有画面在动过一会才恢复、音视频同步；
  • potplayer
    • 播放流畅；
    • 正常播放时进度条时长不正常（21s），拖动画面不会卡住、但音视频有时不同步；
• out3.ts
  • 电影和电视、ACG播放器
    • 播放流畅；
    • 正常播放进度条时长正常（30s），拖动后有声音但画面卡住一会才动、音视频“同步”；
  • VLC
    • 播放流畅；
    • 正常播放进度条时长正常（30s），拖动后有声音但画面会灰屏有画面在动过一会才恢复、音视频“同步”；
  • potplayer
    • 播放流畅；
    • 正常播放时进度条时长不正常（8s），拖动画面和声音都会卡住一会才动；
