    Question Trouble with audio on DV camcorder capture

    Hi,

    I'm running Fedora 11 on a P4. I installed Kino and was able to connect my Canon camcorder via Firewire. Kino recognized the camera and I was able to capture some footage into a raw DV file.

    If I try to play this file in any player (VLC, mplayer, etc) I get no audio, and with mplayer a message about missing codecs. I installed the complete binary codec package for mplayer and am at a loss. I seem to have all of the appropriate libraries installed and current. I've had no luck finding working solutions by Googling. Any ideas out there?

    Thanks,

    What format does your camera record in (audia and video)? Also, what media does it use?

    From the user manual:

    Video: consumer digital VCR SD system
    Audio: PCM Digital Sound 16bit (48kHz/2Ch) 12bit (32kHz/4ch)

    No specifics on the codec used. It uses a mini DV cassette.

    I did find that by selecting a specific (DV2) file format in Kino, I end up capturing an AVI instead of a DV file. My windows players do not seem to like the audio in the avi, and utilities like GSpot come up blank. Does anybody know of any other good utilities that could help me identify the codecs used?

    Thanks again

    I would stream the audio+video feed thru ffmpeg to convert the stream to something like mpeg (2 or 4) video + mp3 audio. You could also transcode to a FOSS format such as mastroika + ogg (or flac) if you prefer to stay away from the mpeg universe.

    If I run ffmpeg -i on the raw .dv file it can't make heads or tails of it. If I capture to the DV2 .avi, it is recognized and ffmpeg converted it to a ntsc-dvd compatible mpg without issue. I think that is the way to go. I'm still curious why the raw .dv is not well supported, but I have a workaround that does the trick.

    Thanks for your help

    Does that fix up the audio for you?

    The MPEG-2 coding works well on my Windows and Linux machines, so I think the issue is resolved.
