关于FFmpeg程序的帮助和其他信息都显示在空格和连字符之后输入的各种选项，示例显示了FFmpeg工具的用法，但是相同的选项对于ffplay、ffprobe和ffserver是有效的。参数是区分大小写的。FFmpeg组件的开发速度很快，从2012年11月开始，一些可用项目列表很快就会不完整，比如X264的支持，不过你可以自己对里面的一些项目列表进行扩展。
FFmpeg中的文本帮助
FFmpeg工具有一个很大的控制台帮助，可以完整显示或关于特定元素 – 解码器，编码器等。下表介绍了可用选项，斜体文本将替换为要显示的项目。 ffplay和ffprobe也有类似的选项。（注意：有一些倾斜的命令行，我这边显示出来之后并不是倾斜的，请大家谅解）
| 基础的助 | 选中的项目的帮助 |
|---|---|
| ffmpeg -? or ffmpeg -h | ffmpeg -h decoder=decoder_name |
| 额外的帮助/扩展的帮助 | 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 |
例如，要显示关于FLV解码器的信息，我们可以使用以下命令:
ffmpeg -h decoder=flv控制台的输出是：
Decoder flv [FLV / Sorenson Spark / Sorenson H.263 (Flash Video)]: Threading capabilities: no Supported pixel formats: yuv420p完整的帮助是非常长的，请参见本章末尾的格式化解决方案，下面我给大家接了一个图，这是在我的电脑上显示的结果：
可用的比特流过滤器
显示内置的比特流过滤器的命令是:
ffmpeg -bsfs| 比特流控制器 |
|---|
| text2movsub |
| remove_extra |
| noise |
| mov2textsub |
| mp3decomp |
| mp3comp |
| mjpegadump |
| mjpeg2jpeg |
| imxdump |
| h264_mp4toannexb |
| dump_extra |
| chomp |
| aac_adtstoasc |
我的电脑上显示的如下：
可用的解码器
可以使用-codecs选项显示可用的解码器，我们可以使用以下命令:
ffmpeg -codecs| 解码器 |
|---|
| D….. = Decoding supported |
| .E…. = Encoding supported |
| ..V… = Video codec |
| ..A… = Audio codec |
| ..S… = Subtitle codec |
| …I.. = Intra frame-only codec |
| ….L. = Lossy compression |
| …..S = Lossless compression |

可用的协议
对于显示可用的文件协议，下一个命令是:
ffmpeg -protocols下面是支持的文件协议：
| Input:（输入） |
|---|
| applehttp |
| cache |
| concat |
| crypto |
| file |
| gopher |
| hls |
| http |
| httpproxy |
| mmsh |
| mmst |
| pipe |
| rtp |
| tcp |
| udp |
| rtmp |
| rtmpe |
| rtmps |
| rtmpt |
| rtmpte |
| Output:(输出) |

可用的音频样本格式
FFmpeg中包含的音频样本格式可以通过命令显示:
ffmpeg -sample_fmts| 名称 | 位深度 |
|---|---|
| u8 | 8 |
| s16 | 16 |
| s32 | 32 |
| flt | 32 |
| dbl | 64 |
| u8p | 8 |
| s16p | 16 |
| s32p | 32 |
| fltp | 32 |
| dblp | 64 |
我电脑上显示出来的样本格式多了两个
FFmpeg版本
版本的ffmpeg可以显示为 -version 选项，下一个结果是在2012年11月25日创建的官方构建窗口的显示结果。
ffmpeg -version
有关ffmpeg配置的详细信息，请参见词汇表。
使用MORE命令来实现输出格式。
由于help命令、可用过滤器命令、格式命令等的输出很长并且通常不适合一个屏幕，所以可以使用更多命令来显示从一开始就按顺序将输出文本进行格式化，下一个屏幕由 按下空格键，按Enter键后显示下一行(只会多显示一行)，按Q或q将退出预览。 语法是
ffmpeg -help | more
或使用更短的形式：
ffmpeg -h|more还可以使用更多的命令来显示文本文件，内容再次被划分为适合一个屏幕，语法是:
more filename.txt可以通过输入显示更多命令的附加参数:
help more重定向输出到文件
有时需要精确研究帮助命令，可用过滤器命令，格式命令等，为了将这些信息保存到文本文件中，可以使用下一个命令：
ffmpeg -help > help.txt该命令将在当前目录中创建一个名为help.txt的新文件，并将其保存到ffmpeg help的内容中。 如果具有相同名称的文件已经存在，它将被覆盖。 要将输出文本附加到现有文件而不覆盖其内容，请使用两个大于符号”>”：
ffmpeg -help > data.txt
ffmpeg -filters >> data.txt现在文件data.txt包含ffmpeg帮助，后面跟着可用过滤器列表。
下图是我打印出来的data.txt信息：
