《FFmpeg Basics》中文版-02-显示帮助和功能

写在前面如果您对音视频技术感兴趣，可以订阅我的专题:音视频专辑也可以关注我的简书账户：张芳涛，我后期会发布更多的音视频以及图像处理方面的文章。正文关于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 -hffmpeg -h decoder=decoder_name额外的帮助/扩展的帮助ffmpeg -h encoder=encoder_nameffmpeg -h long or ffmpeg -h fullffmpeg -h demuxer=demuxer_nameffmpeg –? topic or ffmpeg -h topicffmpeg -h muxer=muxer_name

ffmpeg -? or ffmpeg -h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：这是在我电脑上系那是出来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
