Warning
- The hackrf is not designed to be connected directly to AV equipment and could be damaged by, or cause damage to, your receiver.
- Please ensure no DC voltages or control signals are sent back into the hackrf, and that the RF power levels out of the hackrf are not too high for your receiver.
WHAT'S IT DO
Generates a PAL, NTSC, SECAM, D/D2-MAC video signal from a video file, stream or test pattern. Also supports older 819, 405, 240 and 30 line standards, as well as the NASA Apollo video standards, both colour and mono.
Input is any file type or URL supported by ffmpeg.
Output can be to a file, HackRF, fl2k-supported VGA adaptors or any SDR supported by SoapySDR.
It also supports:
- Teletext (625-line only)
- NICAM stereo audio
- Videocrypt I/II/S hardware support
- Partial Nagravision Syster hardware support
- Analogue Copy Protection system, similar to Macrovision
WHAT'S IT NOT DO (yet)
- An optional notch filter for the colour subcarrier would be nice
WHAT IT WON'T DO
- DVB or other pure digital signals
- Bring back Firefly :(
Depends on libhackrf and various ffmpeg libraries.
