這篇具有很好參考價值的文章主要介紹了ffmpeg的使用不簡單。希望對大家有所幫助。如果存在錯誤或未考慮完全的地方，請大家不吝賜教，您也可以點擊"舉報違法"按鈕提交疑問。

ffmpeg功能強大，它的使用實在是不簡單?？纯此S帶的使用說明有多少？能不能看懂？

應(yīng)該怎樣使用？怎樣靈活使用？

Universal media converter
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

Getting help:
? ? -h ? ? ?-- print basic options
? ? -h long -- print more options
? ? -h full -- print all options (including all format and codec specific options, very long)
? ? -h type=name -- print all options for the named decoder/encoder/demuxer/muxer/filter/bsf/protocol
? ? See man ffmpeg for detailed description of the options.

Per-stream options can be followed by :<stream_spec> to apply that option to specific streams only. <stream_spec> can be a stream index, or v/a/s for video/audio/subtitle (see manual for full syntax).
