Audio from linux.conf.au 2005 continued

    Further to the previous post on the linux.conf.au 2005 audio, a gentleman named Matt kindly wrote in with these thoughts:

    Hi Michael,
    
    Prompted by some of the other Fluendo guys, I took a look at the sample
    ogg file you uploaded of the LCA streams. We think we've figured out
    roughly what the problem was, so I thought I'd let you know...
    
    We think the machine doing the DV reading/encoding was falling behind
    (possibly due to too high CPU usage, but possibly because of an issue in
    the dv grabber gstreamer component - we're discussing what we might do
    to solve some of these issues in the future.
    
    Unfortunately, the result of this is that the raw DV data is simply lost
    - the remaining data was encoded fine (there are no errors in the vorbis
    data according to my validation tools), but there's no possible way to
    recover the bits that went missing. There are a couple of minor muxing
    problems in the actual ogg files, which can be fixed easily enough (I've
    written some tools to help with this, and Conrad Parker has some too,
    let me know if you want to know how to fix these up - they confuse some
    players a bit), but the talk in that sample file is still pretty much
    incomprehensible due to the missing data after repairing the ogg-level
    errors.
    
    Mike
    


    So there you go.

    Er, you mean "a gentleman named Mike" :)

    It's a real shame the audio didn't work out. Call me old-fashioned, but wouldn't slides, people's speaking notes or written papers be almost as good, though? Audio/video files can sometimes actually be tedious because you need to find the time to go through and listen to or watch them. It's often much faster for a busy person to process the written word.
