js1k2017 - NO SIGNAL

Compo entry for http://js1k.com/2017-magic/, demo url: http://js1k.com/TODO

NO SIGNAL shows an EBS TV screen featuring visual glitches.

Random Notes:

• Build Process: Babili as minifier - Babili processed files compress better with Regpack
• Regpack options: REGPACK_OPT5="- --useES6 true --hash2DContext --contextVariableName 'c' --crushGainFactor 4 --crushLengthFactor 1 --crushCopiesFactor 0" - please see minime.sh
• JPEG Glitcher looks great in Chrome and Firefox, Safari however looks like it corrects the error better (thus the result looks worse)

Features:

• HTML5 Audio (Noise, Gain, Oscillator, Merger)
• Adaptive audio gain
• UTF8 Fonts
• JPEG Glitcher using canvas.toDataURL
• Full screen Scanlines
• Full screen Color Glitcher (shift one channel)
• TV Testscreen (EBS) generator
