Hello there, I'm a university student and our professor assigned us as a project to build a theora encoder/decoder. I need some help on some info that I didn't manage to find in Theora's reference. I am building a function that calculates motion estimation. When making motion estimations must I scan each and every macroblock in coded order? After that the motion vectors should be

Hi, We're testing CELT (version 0.7.1) error resilience capability. We've used already celtdec packet-loss options. Hence we know what to expect in case of whole packet loss. How does Celt respond to a broken encoded packet? Is it always better to discard it and decode the missing frame through decode_lost? We have the hardware capability of protecting the frame with multiple CRCs.

Hi Dovecot team, I need help in configuring HA/resilence for my dovecot (POP3/IMAP) server. I have one RHEL Linux POP3/IMAP server with Dovecot version 2.2.10. I also installed the postfix(version: 2.6.6) in it. At present it have around 10 domains and each domain is having around 20 email boxes. It has very simple configuration. User's reading the email via some internal

Hello, 1) If i create a raidz2 pool on some disks, start to use it, then the disks'' controllers change. What will happen to my zpool? Will it be lost or is there some disk tagging which allows zfs to recognise the disks? 2) if i create a raidz2 on 3 HDs, do i have any resilience? If any one of those drives fails, do i loose everything? I''ve got one such pool and

Thank you Aki for the reply. But I cannot disturb the version at present as it is a live server and thousands of emails will circulate every hour. Could you please suggest me how to create HA/resilience for the existing environment. I have another server ready with the similar configuration. Please provide any steps/link for me to proceed on this? It will be a great help to me. Thanks, Kishore

Hi, I have been on a documentation kick recently. I finally updated my VP3 format document tonight: http://www.pcisys.net/~melanson/codecs/vp3-format.txt v0.2: October 9, 2003 - expanded section "Reversing the DC Prediction" - added Appendix B: Theora Differences Feel free to look it over and point out any glaring mistakes. I can't wait to see how much sense it makes to

But when I tryed to do the same using real number (i.e. 0.1 + 0.2 == 0.3) I obtained an unusual FALSE. In the online help there are some tricks for this problem. It

I hope this list is small enough for not beeing banned when introducing oneself. So... Hi, I just subscribed to the theora-lists. I'm from the XVID project, so I know a deal about video and MPEG-4 in particular, but nothing about Vorbis/Theora etc., That's why I'm here, because I'm interested in patent-free alternatives. I guess there is no documentation of the current status

Thank you all for the replies.... I have the test environment with the same configuration. But I have been asked to go with same environment for HA/Resilience in Live. Yes, I have only one Live server. It is configured in "Maildir" format. The data stores on a Network / Shared Storage (But definitely not local disk, its a mount point). I have been asked to create a HA/Resilience for

Also you should probably use dovecot director to ensure same user sessions end up on same server, as it's not supported to access same user on different backends in this scenario.

On the whole we are pleased with our trials of dovecot to replace UW-IMAP. But (ah!) we have hit one particular problem, in which we think dovecot could probably benefit from a resilience improvement. We're running dovecot on Fedora Core 5 (FC5), with passwd map details supplied by NIS. We have found that "nscd" sometimes thinks that a username is invalid, even though it is valid.

Hi, Is somewhere alghorithm description of encoder process implemented in libtheora? May be some drafts? May be frame dataflow throw encoder stages?

If you just want active/standby, you can simply use corosync/pacemaker as other already suggest and don?t use Director. I have a dovecot HA server that uses floating IP and pacemaker to managed it, and it works quite well. The only real hard part is having a HA storage. You can simply use a NFS storage shared by both servers (as long as only one has the floating IP, you won?t have issue with the

Dan, In reviewing the code, derf came across the DCSearchPoints array in QuadCodeDisplayFragments(), encode.c:696. It looks like it specifies a search order for nearby coded fragments for prediction if there isn't a nearest neighbor. However, the upper search bound is defined as *0*, so the search loop (line 917) is never executed and it always falls back to the last coded fragment.

You can do it using replication, https://wiki.dovecot.org/Replication but since you have no staging/test environment, I would advice you to get one.

Hello, you need to "clone" the first server, change the ip address, mount the same maildir storage and use some mechanism to share the accounts database. Then you need to put a TCP load-balancer in front of the servers an you are good to go. This is the easiest solution if you already have in the network an appliance that can do LB. For instance if you already have a firewall with

Hello folks, I have been asked about the resilience of samba clients when faced with a domain controller failure. My client's environment has multiple Windows Domain Controllers (we'll call them dc1 - dc9). Assuming that domain replication operates as expected (and does, from Windows workstation point of view), what should I expect if (when) the domain controller that initiated a

Yes, but it works for small systems if you set IP source address persistence on LB or even better, if you set priority to be Active/Standby. I couldn't find a good example with dovecot director and backend on the same server, so adding another two machines seems overkill for small setups. If someone has a working example for this please make it public ! Quote from
