    Someone know if work?
    Or a good alternative with mpeg2 hw on board?
    Thanks

  2. Probably not. There are drivers for the SAA7134 chip it uses, but that probably leaves out the MPEG2 hardware compression part. The Hauppauge 350 seems to work. But is hardware MPEG2 really needed?

    With software encoding cards like hauppauge impactVCB i
    have serious problems of audio desync and frame lost,i talk about it here https://forum.videohelp.com/threads/248203-Converting-VHS-to-DVD-under-Linux-HOWTO?p=23...=1#post2316866
    So i want a hw mpeg2,linuxtv said
    "A card with hardware MPEG2-encoder like a Hauppauge PVR-150/250-350 can work around this problem as the trouble of synchronizing is moved from software to the MPEG encoder/muxer on the hardware of the card. "
    Consider my card doesn't had audio card and i use my pci integrated mobo card,can be this the problem for audio desync?

  4. Hauppauge ImpactVCB series doesn't have any audio inputs. Using the soundcard for audio and another device for video can cause desync. The Hauppage 350 seems to be better, because it captures both video and audio, and, as LinuxTV states "the trouble of synchronizing is moved from software to the MPEG encoder/muxer on the hardware of the card". You don't have the problem that one devices has to wait for the other with this.

    However, do you need realtime MPEG2 capture?

    There is alternative?
    I try yuv-raw avi and lavc with same results

  6. With same results you mean dropped frames/audio not in sync? I think that is because the video capture and audio capture is done by 2 different devices. IMHO using a capture card with audio input will solve this problem. On the MythTV wiki there is a short list of cards that work under Linux:

    Your system, according to the other thread, is fast enough for uncompressed capture. I guess you want a hardware encoder to prevent desync?

    Thanks i will try my usb card grabby,works bad with my vcr,
    hope work better with a pro VCR with native s-video output
    For other yes,i mean desync.

    I see from your orher thread you run slackware. Tht's not a distro I know anything about. I don't even know which package management tools they use. Linux isn't one thing. I don't think there are many slackware users here, so I'd suggest joining this forum if you haven't already ....

  10. I have another card,maybe not good as canopus one,but run at first boot.
    The canopus is probably unsupported because load no module and of course didn't create the /dev/video
