A patched version of ffmpeg is required .. :) he wrote that he will open the source if enough people show interest and contact him by mail -- so feel free to bug him! For the meantime it's probably a nice challenge for most of us to follow the approach and write a bitmap generator... maybe it's even one day possible to do the modulation in realtime, in some cases it might be possible to let the GPU do some work... In any case the approach to use the video DAC for direct HF conversion is very interesting. It would be nice if somebody spends some time to do further research in this direction. Combined with the Oscar's multiplexer code and Marek's DSMCC/MHP carousel (both GPL'd on linuxtv.org) one day a complete playout center in software may become true. Assuming that it is possible to do the modulation in realtime on normal hardware in not too far future. Holger
