They are using X-Content-Duration and that failure rate is pretty good.
I think that the last time I heard failure numbers from a large provider
they were in the 20% range.

Hi Chris,
Yes, we already use X-Content-Duration to avoid loading the video
twice.
The failure rate is about 0.2% - in ~0.1% cases the ffmpeg2theora
crashed, and in 0.1% cases it can not transcode. So the overall success
rate is pretty high.
We will follow your advice and use the 1.1 encoder.
Thanks,
Hailin
Great, let me know. (Hope the style + functionality works well and
performs well!)
In 3.6 we've done a lot of work to improve seek performance. (Fewer
http requests to seek.) I might have mentioned this before but I'm
hoping that you guys are using X-Content-Duration to help lessen the
load on your servers?
Also since you guys did the transcoding did you have a failure
rate? And if you can say what tools are you using? You are one of
the first people who have tried this at scale and I'm curious what
your experience was.
Also I'm hoping that you transcoded using the 1.1 encoder - it's a
pretty big step up.
Once again, anything you need help with, please let us know.

Hey, everyone. This was actually an email that was supposed to go to
our internal mailing list for parter-related things. We're all friends
here so I'd ask that you not re-post this as a favor to me, because it's
my mistake.
