DCP-o-matic

Nice! Glad it worked!
I had never tried this before (never seen SLV here in France) and it's good to know ISDCF's script is operational even with a more recent ffmpeg than 3.2.4 and easy to use.

(Best is to donate to Carl if you want to, but thanks it's much appreciated, glad I could help!)

Dan

Film screening is tonight, will try to snap some pics of Hearing Impared people using it was well.

Carl: Would be really nice if you'd add a Bitcoin address for donations.
Paypal and bank transfers are impossible here in Brazil because of taxes and also because your currency is so devaluated that it's hard to make a big donation but smaller ones in BTC or Lightning Address is doable.

Also, such a pity that Christian Schultz has disappeared from the forum.
If you notice the brand of the sign language receptor in the picture is "Riole" which is his company (or he works there).

Anyways, again: thanks a lot to all in the forum, especially Dan for the help and Carl for the sofware.
You guys rock!

Hi,

Did anyone have any luck contacting Christian about this video? It seems like it's a useful thing!

Maybe you can contact the Company and try to access Cristian.

Hi, guys,
Does anyone still have the documents linked in the original video?
I couldn't find the Ubunt image and the .PDF file.
I'm trying to understand the whole process, but I'm not familiar with Linux, so I don't know how to run the Sign Language encoder/decoder.
Any help is amazing.
Thanks in advance

I have just made a graphical interface which only works under Windows and which allows me to create the wav file for channel 15 of the DCP.
If this helps anyone.

1) The video frame rate shall be 24.0 fps regardless of any other DCP frame rates in use.
2) The video shall be 480 pixels wide and 640 pixels high (i.e., portrait orientation).


my program is running on windows and just making the complete PCM wav file like the ISDCF 'encode' script (https://github.com/ISDCF/Sign-Language-Video-Encoding)
Structure of a PCM bloc :
H1 = 0xFFFFFFFF
Lv = Length of VP9 segment in bytes (32-bit unsigned integer, big-endian)
Lb = Length of PCM Block in bytes (32-bit unsigned integer, big-endian)
Le = Length of VP9 EBML Header in bytes (32-bit unsigned integer, big-endian)
H2 = 0xFFFFFFFF
E = VP9 EBML Header
P = A sequence of Lb – Lv – Le – 20 null bytes

1) create a folder in your desktop
2) put in this folder the executable Sign-Language-Video-Encoding-master.exe ( https://wetransfer.com/downloads/efdccf ... 301/040dcf
)
3) download the ffmpeg binaries for windows (i.e v6.0) : https://www.gyan.dev/ffmpeg/builds/pack ... _build.zip
4) add ffmpeg.exe ffprobe.exe into the folder
5) run the application


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