一. 用ffmpeg播放
ffserver
它有两个参数需要注意
-d --> enalbe debug mode
-f --> 指定配置文件的路径,如果没有-f参数则默认是/etc/ffserver.conf
1. ffmpeg编译完成后会生成
ffserver
ffmpeg
ffplay

ffserver.conf文件(ffmpeg源码下的doc目录中有ffserver.conf里面有详细解析)
  1. HTTPPort 8091
  2. HTTPBindAddress 0.0.0.0
  3. MaxClients 10
  4. MaxBandwidth 50000
  5. <Feed feed1.ffm>
  6. file /tmp/feed1.ffm                 -->缓冲文件的路径是/tmp/feed1.ffm
  7. FileMaxSize 10M                     -->缓冲文件最大是10M
  8. </Feed>

  9. <Stream feed1.mjpeg>
  10. Feed feed1.ffm
  11. Format mjpeg
  12. VideoSize 640x480
  13. VideoFrameRate 10
  14. VideoBitRate 2000
  15. VideoQMin 1
  16. VideoQMax 10
  17. </Stream>


2. 运行结果
2.1 首先运行server端
  1. cong@msi:/work/ffmpeg/out/bin$ ./ffserver -d -f ./ffserver.conf
  2. ffserver version 2.7.2 Copyright (c) 2000-2015 the FFmpeg developers
  3.   built with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1)
  4.   configuration: --enable-shared --prefix=../out
  5.   libavutil 54. 27.100 / 54. 27.100
  6.   libavcodec 56. 41.100 / 56. 41.100
  7.   libavformat 56. 36.100 / 56. 36.100
  8.   libavdevice 56. 4.100 / 56. 4.100
  9.   libavfilter 5. 16.101 / 5. 16.101
  10.   libswscale 3. 1.101 / 3. 1.101
  11.   libswresample 1. 2.100 / 1. 2.100
  12. ./ffserver.conf:19: Setting default value for video bit rate tolerance = 500000. Use NoDefaults to disable it.
  13. ./ffserver.conf:19: Setting default value for video rate control equation = tex^qComp. Use NoDefaults to disable it.
  14. ./ffserver.conf:19: Setting default value for video max rate = 4000000. Use NoDefaults to disable it.
  15. ./ffserver.conf:19: Setting default value for video buffer size = 4000000. Use NoDefaults to disable it.
  16. ./ffserver.conf:50: Setting default value for video bit rate tolerance = 75000. Use NoDefaults to disable it.
  17. ./ffserver.conf:50: Setting default value for video rate control equation = tex^qComp. Use NoDefaults to disable it.
  18. ./ffserver.conf:50: Setting default value for video max rate = 600000. Use NoDefaults to disable it.
  19. ./ffserver.conf:50: Setting default value for video buffer size = 600000. Use NoDefaults to disable it.
  20. Mon Sep 14 18:18:38 2015 Deleting feed file '/tmp/feed1.ffm' as stream counts differ (3 != 2)
  21. Mon Sep 14 18:18:38 2015 FFserver started.
  22. Mon Sep 14 18:18:51 2015 127.0.0.1 - - New connection: POST /feed1.ffm
  23. Mon Sep 14 18:18:53 2015 127.0.0.1 - - [POST] "/feed1.ffm HTTP/1.1" 200 671744
2.2 然后在另一个终端运行ffmpeg
ffmpeg用来把本地摄像头中的数据转为feed1.ffm缓存起来
  1. cong@msi:/work/ffmpeg/out/bin$ ./ffmpeg -v verbose -r 5 -s 640x480 -f video4linux2 -i /dev/video0 http://localhost:8091/feed1.ffm
  2. ffmpeg version 2.7.2 Copyright (c) 2000-2015 the FFmpeg developers
  3.   built with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1)
  4.   configuration: --enable-shared --prefix=../out
  5.   libavutil 54. 27.100 / 54. 27.100
  6.   libavcodec 56. 41.100 / 56. 41.100
  7.   libavformat 56. 36.100 / 56. 36.100
  8.   libavdevice 56. 4.100 / 56. 4.100

2.3 查看
这样在/tmp目录下就会生与一个feed1.ffm作为缓冲文件
  1. cong@msi:/work/ffmpeg/out/bin$ ls -l /tmp/feed1.ffm
  2. -rw-rw-r-- 1 cong cong 888832 Sep 14 18:24 /tmp/feed1.ffm

二. 实时流媒体的播放rtsp
1. 修改ffserver的配置ffserver.conf
  1. HTTPPort 8091
  2. RTSPPort 5454                     -->这儿添加了rtsp的port
  3. HTTPBindAddress 0.0.0.0
  4. MaxClients 10
  5. MaxBandwidth 50000
  6. <Feed feed1.ffm>
  7. file /tmp/feed1.ffm
  8. FileMaxSize 10M
  9. </Feed>

  10. <Stream feed1.mjpeg>
  11. Feed feed1.ffm
  12. Format mjpeg
  13. VideoSize 640x480
  14. VideoFrameRate 10
  15. VideoBitRate 2000
  16. VideoQMin 1
  17. VideoQMax 10
  18. </Stream>


  19. <Stream live.h264>                -->rtsp的配置
  20. Format rtp
  21. Feed feed1.ffm
  22. #VideoCodec libx264
  23. VideoFrameRate 24
  24. VideoBitRate 300
  25. #VideoSize 480x272
  26. VideoSize 640x480
  27. #AVPresetVideo default
  28. #AVPresetVideo superfast
  29. AVOptionVideo flags +global_header

  30. PixelFormat yuv420p
  31. AVOptionVideo me_range 4
  32. AVOptionVideo qdiff 4
  33. AVOptionVideo qmin 2
  34. AVOptionVideo qmax 51

  35. #MulticastAddress 224.124.0.1
  36. #MulticastPort 5000
  37. #MulticastTTL 1

  38.   
  39. NoAudio
  40. #AudioCodec libfaac
  41. #AudioBitRate 32
  42. #AudioChannels 2
  43. #AudioSampleRate 22050
  44. #AVOptionAudio flags +global_header
  45. </Stream>
2. 运行
  1. a.开启server
  2. cong@msi:/work/ffmpeg/out/bin$ ./ffserver -d -f ./ffserver.conf
  3. b.开启ffmpeg
  4. cong@msi:/work/ffmpeg/out/bin$ ./ffmpeg -v verbose -r 5 -s 640x480 -f video4linux2 -i /dev/video0 http://localhost:8091/feed1.ffm
  5. c.本地用ffplay播放
  6. cong@msi:/work/ffmpeg/out/bin$ ./ffplay rtsp://localhost:5454/live.h264
如果没有问题,则ffplay就会播放出摄像头的影像。

三.顺序流媒体的播放
上面的RTSP是实时的,类似于网络视频聊天,而这个顺序流媒体即看网络电影
3.1 ffserver.conf
  1. <Stream test.mpg>         --> 这个针对于mpg格式
  2. File /tmp/minzu.mpg       --> ffmpeg源码目录下的doc/ffserver.conf中对Format参数的说明:
  3. Format mpeg               --> mpeg: MPEG-1 multiplexed video and audio
  4. </Stream>

  5. <Stream test.avi>        -->这个针对于avi格式
  6. File /tmp/minzu.avi
  7. Format avi               -->avi: AVI format (MPEG-4 video, MPEG audio sound)
  8. </Stream>               
完整的ffserver.conf如下:
  1. cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ cat ffserver.conf
  2. HTTPPort 8091
  3. HTTPBindAddress 0.0.0.0
  4. MaxClients 10
  5. MaxBandwidth 50000

  6. <Stream test.mpg>
  7. File /tmp/minzu.mpg
  8. Format mpeg
  9. </Stream>

  10. <Stream test.avi>
  11. File /tmp/minzu.avi
  12. Format avi
  13. </Stream>

3.2 视频文件的格式
  1. cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ ./ffplay /tmp/minzu.mpg
  2.     Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv), 640x360 [SAR 1:1 DAR 16:9], max. 2516 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc
  3.     Stream #0:1[0x1c0]: Audio: mp2, 44100 Hz, stereo, s16p, 224 kb/s

  4. cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ ./ffplay /tmp/minzu.avi
  5.     Stream #0:0: Video: mpeg4 (Advanced Simple Profile) (XVID / 0x44495658), yuv420p, 640x360 [SAR 1:1 DAR 16:9], 1511 kb/s, 25 fps, 25 tbr, 25 tbn, 25 tbc
  6.     Stream #0:1: Audio: mp3 (U[0][0][0] / 0x0055), 44100 Hz, stereo, s16p, 224 kb/s
3.3 播放测试
cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ ./ffplay
cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ ./ffplay
上面两个播放分别都可以看到视频并听到声音
注意:
    ffserver.conf中的配置一定要与要播放的视频格式相对应
