(I had meant to post this earlier, but...) I finally got around playing with this cx88 card on FreeBSD, and can report I was able to grab pal-b composite in using the cx88 tool and ffmpeg ...when its not panicing. First, what I did: I applied the following patch that: 1) adds a missing case CX88_CARD_ID_WINTV_HVR4000 that prevented my card from working, and 2) allows selecting non-tuner inputs by passing `magic' channel names via -c: "input_mux2" (composite in on my card), "input_mux3" (most likely s-video in here), and "input_mux4" (I don't know if that's used on my card, but it might be on others.) Index: client/analog/cx88_analog_driver_factory.h @@ -53,6 +53,8 @@ case CX88_CARD_ID_PCHDTV_HD5500: return (new pchdtv_hd5500(cx88conf, tunerconf, devnode, captures, mode, slave, pip_driver, error)); case CX88_CARD_ID_PIXELVIEW_XCAPTURE: + // XXX this one was missing - probably need to add some more... + case CX88_CARD_ID_WINTV_HVR4000: return (new cx88_analog_driver(cx88conf, tunerconf, devnode, captures, mode, slave, pip_driver, error)); default: return NULL; Index: client/analog/cx88_analog_driver.cpp @@ -351,6 +351,14 @@ } cx88_video_capture capture; capture.in_input_source = CX88_VIDEO_INPUT_MUX1; + // XXX hack to allow selecting non-tuner inputs + if (!m_channel_name.compare("input_mux2")) + capture.in_input_source = CX88_VIDEO_INPUT_MUX2; + else if (!m_channel_name.compare("input_mux3")) + capture.in_input_source = CX88_VIDEO_INPUT_MUX3; + else if (!m_channel_name.compare("input_mux4")) + capture.in_input_source = CX88_VIDEO_INPUT_MUX4; + capture.in_input_type = CX88_VIDEO_INPUT_COMPOSITE; capture.in_input_options = 0; capture.in_lock_timeout_ms = 1000; then I edited cx88.xml to `define' input_mux2 to be pal-b by adding a new profile "EU_UHF_PALB" for it and using that as its `channel': (thats why this is a hack, and btw the default doesn't work, you still have to specify input_mux2 via -c.)

I also played with vlc (I mainly wanted to be able to have composite in in a window, thats also why I didn't play with audio yet), but that still seems to suffer from sync(?) problems, i.e. I get jerky video after a while. If anyone wants to investigate, instead of ffmpeg above I ran vlc --demux rawvideo --rawvid-fps 25 --rawvid-width 768 --rawvid-height 576 --rawvid-chroma I422 vpipe (I first wanted to do this with mplayer but the closest I got, mplayer -demuxer rawvideo -rawvideo w=768:h=576:format=422p:size=884736 vpipe still gets false colours.)
