Sign Language Video Encoding For Digital Cinema
A simple encoder and decoder that conforms to the ISDCF Document on Sign Language Video Encoding.
FFmpeg v3.2.4 is required. In particular, the executables
ffplay must be in your path.
Note: later versions of FFmpeg are known to not work at this time.
$ encode-vp9-wav sign-language.mp4
This will generate a wav file suitable for inclusion on channel 15 of a DCP.
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
