01.道可道，非常道。名可名，非常名。无名天地之始。有名万物之母。故常无欲以观其妙。常有欲以观其徼。此两者同出而异名，同谓之玄。玄之又玄，众妙之门。

02.天下皆知美之为美，斯恶矣；皆知善之为善，斯不善已。故有无相生，难易相成，长短相形，高下相倾，音声相和，前後相随。是以圣人处无为之事，行不言之教。万物作焉而不辞。生而不有，为而不恃，功成而弗居。夫唯弗居，是以不去。

03.不尚贤， 使民不争。不贵难得之货，使民不为盗。不见可欲，使民心不乱。是以圣人之治，虚其心，实其腹，弱其志，强其骨；常使民无知、无欲，使夫智者不敢为也。为无为，则无不治。

04.道冲而用之，或不盈。渊兮似万物之宗。解其纷，和其光，同其尘，湛兮似或存。吾不知谁之子，象帝之先。

05.天地不仁，以万物为刍狗。圣人不仁，以百姓为刍狗。天地之间，其犹橐迭乎？虚而不屈，动而愈出。多言数穷，不如守中。

Encoding to Hap from the command line using FFmpeg

For users who prefer working with a command line or need to access advanced encoding settings for Hap the popular FFmpeg library can be used to work with Hap movies.

1. If this is your first time using FFmpeg you may need to install it on your system, or compile it from source. In either case be sure that Snappy is enabled as part of the binary. If you already have FFmpeg on your system with Snappy enabled, you can skip this step.

   You can check that your version of FFmpeg can encode Hap using

   ffmpeg -encoders | grep hap
