Sign Language Video Encoding For Digital Cinema

A simple encoder and decoder that conforms to the ISDCF Document on Sign Language Video Encoding.

Requirements

FFmpeg v3.2.4 is required. In particular, the executables ffmpeg, ffprobe, and ffplay must be in your path.

Note: later versions of FFmpeg are known to not work at this time.

Synopsis

Encoding

$ encode-vp9-wav sign-language.mp4

This will generate a wav file suitable for inclusion on channel 15 of a DCP.

Decoding

You can play the encoded wav track using:

$ decode-vp9-wav sign-language.wav

or to simply extract the vp9 from the wav file:

$ decode-vp9-wav sign-language.wav  >out.vp9
