BTW you might be interested in a ‘fio’ backend I wrote for testing NBD servers. The current public version is here: https://www.spinics.net/lists/fio/msg07831.html but I also now have a version based on libnbd although it's not quite ready for use.

I am trying to using Speex for some Wireless voice transfers. I am using the 8K narrow band but am feeding it 11025 sample rate. Each Speex frame is about 14.5ms instead of 20ms. In order to minimize WiFi packet traffic I am sending 7 Speex frames at a time for a packet rate of about 10 per second so each WiFi packet has about 101ms of voice data. I have three modes 1. Simplex - voice messaging

Tony?s performance sounds significantly sub par from my experience. I did some testing with gluster 3.12 and Ovirt 3.9, on my running production cluster when I enabled the glfsapi, even my pre numbers are significantly better than what Tony is reporting: ???????????????????

I am no Vorbis developer, and I have never looked into the details of Ogg-Vorbis implementation, but since Ogg-Vorbis is a lossy format, there is no one to one correspondence of PCM samples and bytes in the stream. Ogg-Vorbis is also a variable bitrate format. I mean that first the stream has to be reconstituted into uncompressed PCM samples, and only then you can get to the desired sample.

This thread reminded me of Ralph's LCA presentation entitled "Seeking is Hard". <http://xiph.org/~giles/> Not sure if it contains anything you don't already know, but worth a mention. - Josh On 2015-5-20 06:55 , Madison Link wrote: > Thanks. > > > > If decoding from the last packet on the previous page works, I may have > to do that.

Thanks. If decoding from the last packet on the previous page works, I may have to do that. But I was hoping to avoid it. Yes, I may be seeking a lot. A packet spanning multiple pages shouldn't be a problem for me, because I'm only adding index points that represent the beginning of a packet. But does this actually happen for Vorbis? (Aside from large header packets) The large blocks

What is the best practice for seeking to a specific (arbitrary) PCM sample in an Ogg file that contains vorbis, using libvorbis? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipermail/vorbis/attachments/20150518/1d3bb0ae/attachment.htm

hi, im having a table which holds a lot of information. i would like to slice & dice in a BI-manner the table. u guys have any suggestions? table looks a bit like this: user app [appa, appb, appc] action [actiona, actionb, actionc] timestamps ... so it would be cool to sort, drill in&up based on the various dimensions. im not asking for a full bi-solution, but maybe the one or the other

Dear Friends: I am trying to join a Suse 9.1 Server running Samba 3.07 to an NT4 Domain. One part I am confused about is the command "net rpc join -U" ... is the username to be used with this command the name of an administrator on the NT4 PDC? Does that administrator need to be an user on the Samba Server and a member of the "root" group? I successfully join using
