ffmpeg處理RTMP流媒體的命令大全

轉載 2013年09月25日 21:23:55 1、將文件當做直播送至live
[plain] view plain copy

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

?

[plain] view plain copy

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

3、將其中一個直播流，視頻改用h264壓縮，音頻不變，送至另外一個直播服務流

4、將其中一個直播流，視頻改用h264壓縮，音頻改用faac壓縮，送至另外一個直播服務流

[plain] view plain copy

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、將一個高清流，復制為幾個不同視頻清晰度的流重新發布，其中音頻不變
[plain] view plain copy

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、將當前攝像頭，視頻h264、音頻faac壓縮后發布
[plain] view plain copy

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??

經過h264壓縮循環輸出為mp4視頻

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、將普通流視頻改用h264壓縮，音頻不變，送至高清流服務(新版本FMS live=1)
[plain] view plain copy

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