转载请注明本文地址: ffmpeg学习---11.ffmpeg的流媒体服务器与播放器的设置
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)
2. 运行结果
2.1 首先运行server端
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
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
二. 实时流媒体的播放rtsp
1. 修改ffserver的配置ffserver.conf
2. 运行
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
完整的ffserver.conf如下:
3.2 视频文件的格式
3.3 播放测试
cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ ./ffplay http://192.168.4.11:8091/test.mpg
cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ ./ffplay http://192.168.4.11:8091/test.avi
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

这样在/tmp目录下就会生与一个feed1.ffm作为缓冲文件
- cong@msi:/work/ffmpeg/out/bin$ ls -l /tmp/feed1.ffm
- -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
- HTTPPort 8091
- RTSPPort 5454 -->这儿添加了rtsp的port
- HTTPBindAddress 0.0.0.0
- MaxClients 10
- MaxBandwidth 50000
- <Feed feed1.ffm>
- file /tmp/feed1.ffm
- FileMaxSize 10M
- </Feed>
- <Stream feed1.mjpeg>
- Feed feed1.ffm
- Format mjpeg
- VideoSize 640x480
- VideoFrameRate 10
- VideoBitRate 2000
- VideoQMin 1
- VideoQMax 10
- </Stream>
- <Stream live.h264> -->rtsp的配置
- Format rtp
- Feed feed1.ffm
- #VideoCodec libx264
- VideoFrameRate 24
- VideoBitRate 300
- #VideoSize 480x272
- VideoSize 640x480
- #AVPresetVideo default
- #AVPresetVideo superfast
- AVOptionVideo flags +global_header
- PixelFormat yuv420p
- AVOptionVideo me_range 4
- AVOptionVideo qdiff 4
- AVOptionVideo qmin 2
- AVOptionVideo qmax 51
- #MulticastAddress 224.124.0.1
- #MulticastPort 5000
- #MulticastTTL 1
-
- NoAudio
- #AudioCodec libfaac
- #AudioBitRate 32
- #AudioChannels 2
- #AudioSampleRate 22050
- #AVOptionAudio flags +global_header
- </Stream>
- a.开启server
- cong@msi:/work/ffmpeg/out/bin$ ./ffserver -d -f ./ffserver.conf
- b.开启ffmpeg
- cong@msi:/work/ffmpeg/out/bin$ ./ffmpeg -v verbose -r 5 -s 640x480 -f video4linux2 -i /dev/video0 http://localhost:8091/feed1.ffm
- c.本地用ffplay播放
- cong@msi:/work/ffmpeg/out/bin$ ./ffplay rtsp://localhost:5454/live.h264
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
- <Stream test.mpg> --> 这个针对于mpg格式
- File /tmp/minzu.mpg --> ffmpeg源码目录下的doc/ffserver.conf中对Format参数的说明:
- Format mpeg --> mpeg: MPEG-1 multiplexed video and audio
- </Stream>
- <Stream test.avi> -->这个针对于avi格式
- File /tmp/minzu.avi
- Format avi -->avi: AVI format (MPEG-4 video, MPEG audio sound)
- </Stream>
- cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ cat ffserver.conf
- HTTPPort 8091
- HTTPBindAddress 0.0.0.0
- MaxClients 10
- MaxBandwidth 50000
- <Stream test.mpg>
- File /tmp/minzu.mpg
- Format mpeg
- </Stream>
- <Stream test.avi>
- File /tmp/minzu.avi
- Format avi
- </Stream>
3.2 视频文件的格式
- cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ ./ffplay /tmp/minzu.mpg
- 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
- Stream #0:1[0x1c0]: Audio: mp2, 44100 Hz, stereo, s16p, 224 kb/s
- cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ ./ffplay /tmp/minzu.avi
- 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
- Stream #0:1: Audio: mp3 (U[0][0][0] / 0x0055), 44100 Hz, stereo, s16p, 224 kb/s
cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ ./ffplay http://192.168.4.11:8091/test.mpg
cong@msi:/work/ffmpeg/ffmpeg-2.7.2$ ./ffplay http://192.168.4.11:8091/test.avi
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
