ffmpeg处理RTMP流媒体的命令大全

转载 2013年09月25日 21:23:55

 

1、将文件当做直播送至live

ffmpeg -re -i localFile.mp4 -c copy -f flv rtmp://server/live/streamName

ffmpeg -i rtmp://server/live/streamName -c copy dump.flv

3、将其中一个直播流，视频改用h264压缩，音频不变，送至另外一个直播服务流

4、将其中一个直播流，视频改用h264压缩，音频改用faac压缩，送至另外一个直播服务流

ffmpeg -i rtmp://server/live/originalStream -c:a libfaac -ar 44100 -ab 48k -c:v libx264 -vpre slow -vpre baseline -f flv rtmp://server/live/h264Stream

6、将一个高清流，复制为几个不同视频清晰度的流重新发布，其中音频不变

ffmpeg -re -i rtmp://server/live/high_FMLE_stream -acodec copy -vcodec x264lib -s 640×360 -b 500k -vpre medium -vpre baseline rtmp://server/live/baseline_500k -acodec copy -vcodec x264lib -s 480×272 -b 300k -vpre medium -vpre baseline rtmp://server/live/baseline_300k -acodec copy -vcodec x264lib -s 320×200 -b 150k -vpre medium -vpre baseline rtmp://server/live/baseline_150k -acodec libfaac -vn -ab 48k rtmp://server/live/audio_only_AAC_48k

8、将当前摄像头，视频h264、音频faac压缩后发布

ffmpeg -r 25 -f dshow -s 640×480 -i video=”video source name”:audio=”audio source name” -vcodec libx264 -b 600k -vpre slow -acodec libfaac -ab 128k -f flv rtmp://server/application/stream_name

经过h264压缩循环输出为mp4视频

ffmpeg.exe -i INPUT.jpg -an -vcodec libx264 -coder 1 -flags +loop -cmp +chroma -subq 10 -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -flags2 +dct8x8 -trellis 2 -partitions +parti8x8+parti4x4 -crf 24 -threads 0 -r 25 -g 25 -y OUTPUT.mp4

10、将普通流视频改用h264压缩，音频不变，送至高清流服务(新版本FMS live=1)

ffmpeg -i rtmp://server/live/originalStream -c:a copy -c:v libx264 -vpre slow -f flv “rtmp://server/live/h264Stream live=1″
