Mplayer as such will work using dvb:// If you're there, why go further? mplayer -dumpfile bbc1hd.ts -dumpstream -dvbin file=/path/to/channels.conf dvb://BBC1HD (I'm a little further down the "just schedule recordings and let me watch them with mplayer" DVR route ;) If you wish to feed the input directly in to ffmpeg, you need to use [stc]zap to tune the card and then read it from the frontend: ffmpeg -f mpegts -i /dev/dvb/adapter0/dvr0 -c copy out.ts I have definitely built tzap on freebsd before, but currently I'm using DVB-S2 tuners. I just tried building the zap (its now unified) from the tip of dvb-utils, but this fails now, they've added some GNU extensions... Before, it was literally: fetch ..../linuxtv-dvb-apps-tip.tar.gz tar zxf ... cd dvb-utils-*/utils/zap CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib gmake So if piqued, you could dig a little further.. Cheers Tom PS: ffmpeg is perfectly happy operating on a TS file on disk that keeps growing, use the -re (realtime) option so it chases the recording (in fact, it slows it down to process input frames in the input frame rate - same difference?)
