CVBS-Decode - Composite Video Decoder

This repository also contains an experimental CVBS decoder, cvbs-decode, which shares code with ld-decode and vhs-decode. Capable of decoding basic raw digitized NTSC and PAL composite video, including colour if the source is somewhat stable.

RAW CVBS has been captured using CX Cards & CXADC, however, only at lowest gain states, CVBS capture is not possible with the DomesDayDuplicator Rev3 due to input filtering on the hardware.

Test samples & signals can be generated using HackTV

Note for test media generation AJA/Magewell/Blackmagic and even some consumer digital to analogue converters have test generators built-in some prosumer/broadcast decks also have generators built in same for HDV camcorders.


HiFi-Decode & RTL-SDR Decode

Thanks to VideoMem's work on Superheterodyne Decoding Tools we now have a working HiFi Audio Decoder which provides decoding for VHS & Video8/Hi8 HiFi FM tracks which takes uncompressed or FLAC compressed RF captures of HiFi FM signals and outputs standard 24-bit 192khz FLAC or PCM (.wav) stereo files. RTLSDR decode can run in realtime (1~3 sec delay) and provide live playback 8msps RF files and a 48khz 24-bit FLAC file of the decoded audio.

App wont launch on macOS. Just bounces on the dock a few times and does not open. Tried both Intel and Apple Silicon versions on my M1.
