Plugins to allow communicating data over video (Compatible with SDI)

How it works?

datasrc plugin when starting will create http server at 0.0.0.0:9600. All http requests sent there will be queued and put on each frame. To make sure this would be compatible with SDI, data is encoded so it wouldn't contain 0 and 255. datasink reads each incoming frame checks Magic number, decodes content and signals it. (Check examples/data-from-decklink.rs)

Example usage

• cargo build --release
• export GST_PLUGIN_PATH=$(pwd)/target/release
• GST_DEBUG=datasink:4 gst-launch-1.0 datasrc ! video/x-raw,framerate=25/1,width=1920,height=1080 ! datasink

Notes

• 0 and 256 bits are used for sdi synchronization so we cant use them. (https://forum.blackmagicdesign.com/viewtopic.php?f=12&t=147543#p791374)
