如果您對音視頻技術(shù)感興趣，可以訂閱我的專題:音視頻專輯
也可以關(guān)注我的簡書賬戶： 張芳濤，我后期會發(fā)布更多的音視頻以及圖像處理方面的文章低飒。
正文
關(guān)于FFmpeg程序的幫助和其他信息都顯示在空格和連字符之后輸入的各種選項，示例顯示了FFmpeg工具的用法，但是相同的選項對于ffplay蕾各、ffprobe和ffserver是有效的。參數(shù)是區(qū)分大小寫的庆揪。FFmpeg組件的開發(fā)速度很快式曲，從2012年11月開始，一些可用項目列表很快就會不完整缸榛，比如X264的支持吝羞，不過你可以自己對里面的一些項目列表進行擴展。
FFmpeg中的文本幫助
FFmpeg工具有一個很大的控制臺幫助内颗，可以完整顯示或關(guān)于特定元素 - 解碼器钧排，編碼器等。下表介紹了可用選項均澳，斜體文本將替換為要顯示的項目恨溜。 ffplay和ffprobe也有類似的選項符衔。（注意：有一些傾斜的命令行，我這邊顯示出來之后并不是傾斜的糟袁，請大家諒解）
| 基礎(chǔ)的助 | 選中的項目的幫助 |
|---|---|
| ffmpeg -? or ffmpeg -h | ffmpeg -h decoder=decoder_name |
| 額外的幫助/擴展的幫助 | ffmpeg -h encoder=encoder_name |
| ffmpeg -h long or ffmpeg -h full | ffmpeg -h demuxer=demuxer_name |
| ffmpeg –? topic or ffmpeg -h topic | ffmpeg -h muxer=muxer_name |
ffmpeg -? or ffmpeg -h
例如判族，要顯示關(guān)于FLV解碼器的信息，我們可以使用以下命令:
ffmpeg -h decoder=flv
控制臺的輸出是：
Decoder flv [FLV / Sorenson Spark / Sorenson H.263 (Flash Video)]: Threading capabilities: no Supported pixel formats: yuv420p
完整的幫助是非常長的项戴，請參見本章末尾的格式化解決方案形帮，下面我給大家接了一個圖，這是在我的電腦上顯示的結(jié)果：

可用的音頻樣本格式
FFmpeg中包含的音頻樣本格式可以通過命令顯示:
ffmpeg -sample_fmts
| 名稱 | 位深度 |
|---|---|
| u8 | 8 |
| s16 | 16 |
| s32 | 32 |
| flt | 32 |
| dbl | 64 |
| u8p | 8 |
| s16p | 16 |
| s32p | 32 |
| fltp | 32 |
| dblp | 64 |
我電腦上顯示出來的樣本格式多了兩個
FFmpeg版本
版本的ffmpeg可以顯示為 -version 選項鹏秋，下一個結(jié)果是在2012年11月25日創(chuàng)建的官方構(gòu)建窗口的顯示結(jié)果尊蚁。
ffmpeg -version
FFmpeg版本信息
有關(guān)ffmpeg配置的詳細信息，請參見詞匯表侣夷。
使用MORE命令來實現(xiàn)輸出格式横朋。
由于help命令、可用過濾器命令惜纸、格式命令等的輸出很長并且通常不適合一個屏幕叶撒，所以可以使用更多命令來顯示從一開始就按順序?qū)⑤敵鑫谋具M行格式化绝骚，下一個屏幕由 按下空格鍵，按Enter鍵后顯示下一行(只會多顯示一行)祠够，按Q或q將退出預(yù)覽压汪。 語法是
ffmpeg -help | more
想看更多信息的，敲Enter鍵就可以
或使用更短的形式：
ffmpeg -h|more
還可以使用更多的命令來顯示文本文件古瓤，內(nèi)容再次被劃分為適合一個屏幕止剖，語法是:
more filename.txt
可以通過輸入顯示更多命令的附加參數(shù):
help more
重定向輸出到文件
有時需要精確研究幫助命令，可用過濾器命令落君，格式命令等穿香，為了將這些信息保存到文本文件中，可以使用下一個命令：
ffmpeg -help > help.txt
該命令將在當(dāng)前目錄中創(chuàng)建一個名為help.txt的新文件绎速，并將其保存到ffmpeg help的內(nèi)容中皮获。 如果具有相同名稱的文件已經(jīng)存在，它將被覆蓋纹冤。 要將輸出文本附加到現(xiàn)有文件而不覆蓋其內(nèi)容洒宝，請使用兩個大于符號">"：
ffmpeg -help > data.txt
ffmpeg -filters >> data.txt
現(xiàn)在文件data.txt包含ffmpeg幫助，后面跟著可用過濾器列表萌京。
下圖是我打印出來的data.txt信息：
