1, the file is sent as a live broadcast
ffmpeg -re -i localFile.mp4 -c copy -f flv rtmp://server/live/streamName
2. Save the file to a local broadcast media
ffmpeg -i rtmp://server/live/streamName -c copy dump.flv
3, which will be a live stream, use h264 video compression, audio unchanged, sent to another live streaming service
ffmpeg -i rtmp://server/live/originalStream -c:a copy -c:v libx264 -vpre slow -f flv rtmp://server/live/h264Stream
4. in which a live streaming, video switch h264 compression, audio compression faac use, to the other live streaming service
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
5, which will be a live streaming video unchanged audio switch faac is compressed and sent another live streaming service
ffmpeg -i rtmp://server/live/originalStream -acodec libfaac -ar 44100 -ab 48k -vcodec copy -f flv rtmp://server/live/h264_AAC_Stream
6, a high-definition streaming, copied to several different definition video stream to re-release, in which the audio unchanged
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
7, the same function, except that -x264opts options
ffmpeg -re -i rtmp://server/live/high_FMLE_stream -c:a copy -c:v x264lib -s 640×360 -x264opts bitrate=500:profile=baseline:preset=slow rtmp://server/live/baseline_500k -c:a copy -c:v x264lib -s 480×272 -x264opts bitrate=300:profile=baseline:preset=slow rtmp://server/live/baseline_300k -c:a copy -c:v x264lib -s 320×200 -x264opts bitrate=150:profile=baseline:preset=slow rtmp://server/live/baseline_150k -c:a libfaac -vn -b:a 48k rtmp://server/live/audio_only_AAC_48k
8, the current camera and audio capture through DSSHOW, after video h264, audio compression release faac
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
9, a JPG image compression cycle through h264 mp4 video output
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, the common use h264 video stream compression, audio unchanged, to the high-definition streaming service (a new version of 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″
