There was a bug in the transcode script which caused audio to be lost in
the case of an apology slide. This has been rectified, and the video
retranscoded.

If you redownload the video, it should now have audio.

No worries.

There were seven people in the room: highvoltage, tumbleweed, olasd,
pollo, and myself; and bdale and keith as "audience".

In all, that means it was not very well attended, but hey :-)

The slides are very basic; they don't contain a lot of information.
Still, you can get them here:

I did forget to add a slide about the opsis boards, but we talked about
those too, in between the final two slides.

This.

As for my bit, I think sreview performed as I had expected it. There is still
room for improvement (especially in that ffmpeg defaults to pretty horrid
resolution settings for VP8, hadn't noticed that), but other than that
it worked well.

Unless people disagree, I intend to use it for future events, rather
than veyepar. However, I'm not planning to disable the veyepar instance
on vittoria, so it can still be used if needs be.

I think the cameras worked well, we chose good. Their zoom is okay,
their low-light performance is great, nothing more you'd want than that.

As I've said a few times, we should move away from MPEG2 encoding and
onto something that is HTML5-compatible. MPEG2 means sreview can't use
the original encodings for the previews, which makes it take a lot of
time to generate a preview. Additionally, MPEG2 takes a lot of
diskspace, a lot more than the DV recordings did (and those were
horribly inefficient). FOSDEM has had great results with H.264; Mark van
den Borre can tell you more about that. We should investigate this at
the sprint in Cambridge.

Any other thoughts?
