[00:41] <llogan> saste: any comments (since you were the only one with input on ML)? http://pastebin.com/raw.php?i=6B1ege28
[00:44] <saste> llogan, i find annoying when I'm subscribed to a new ML without my explicit approval
[00:45] <llogan> one reason i'm not going to auto-subscribe
[00:45] <saste> so I'd suggest to advertise the current ffserver-user subscribers of the move
[00:45] <saste> you could keep the ML active, but tell all the posters to move to ffmpeg-user
[00:46] <saste> yes an option would be to forward ffserver-user mails to ffmpeg-user
[00:46] <saste> i don't have a strong opinion on that
[00:46] <Compn> i wasnt suggesting subscribing them w/ email subscriptions
[00:46] <llogan> i already made two announcements on ffserver-user.
[00:46] <Compn> only putting their emails in so they could post, automatically
[00:46] <saste> you could leave ffserver-user for a month or so
[00:47] <saste> i don't think there is much traffic anyway
[00:47] <saste> and send a mail every week advertising that the list will be closed in X days
[00:47] <saste> and providing instructions/link to subscribe to ffmpeg-user
[00:48] <llogan> i already said today is it's last day (on jan 27 and again today).
[00:51] <saste> llogan, i think it's safe to remove the list anyway
[00:52] <saste> it would be a bit annoying for the few subscriber to move to an high traffic list
[00:52] <saste> but should be allow a better support, since there will be more feedback
[00:52] <llogan> and they can always disable delivery on their choice.
[00:54] <saste> i'm fine with it
[01:06] <llogan> michaelni: please rmlist ffserver-user at your convenience
[01:45] <michaelni> llogan, ill wait 24h to give people a last chance to raise objections and then delete it
[02:03] <llogan> ok

[12:20] <kierank> it is always morning on irc
[12:23] <michaelni> that proofs the earth cant be flat
[12:36] <TimNich> sometimes feels like a moebius loop!

[13:09] <michaelni> TimNich, a moebius loop is unlikely because if it was that way that moebius loop could be seen by simply looking up from some places

[21:05] <Zeranoe> Could anyone tell me the current status of GPU encoding/decoding? I see NVIDIA provides a H.264 encoder/decoder that works off of CUDA. I'm interested in starting a LGPL GPU encoder
[21:08] <nevcairiel> in general? only fixed presets, quality below software encoders without a significant speed advantage in many cases
[21:08] <nevcairiel> for encoding, that is
[21:09] <nevcairiel> decoders are usually working quite well, provide bit-exact output, speed is usually below any modern CPU, only real use-case is on embedded/mobile
[21:10] <nevcairiel> and limited to mainstream profiles of course, for ex. h264 only 8-bit 4:2:0 baseline/main/high, both for enc/dec
[21:12] <Zeranoe> nevcairiel: Is the speed below CPU encoding because of limitations of the GPU? Is there a possibility to make an encoder/decoder that would out preform CPU encoders/decoders?
[21:12] <nevcairiel> it always depends what quality you're looking for
[21:13] <nevcairiel> and what kind of gpu you have =p
[21:13] <nevcairiel> latest nvidia models for example have a fixed function encoder, earlier models implemented it in cuda
[21:13] <nevcairiel> the tests i remembered, running x264 on settings that resulted in similar quality and filesize, the speed was pretty similar
[21:13] <wm4> what's the use case for GPU encoding? cameras?
[21:14] <nevcairiel> video conferencing, i guess
[21:14] <Zeranoe> nevcairiel: 
[21:14] <nevcairiel> or if you go into the phone market, camera recordings as well, i suppose
[21:15] <Zeranoe> nevcairiel: Does FFmpeg support  any GPU features?
[21:15] <nevcairiel> ffmpeg supports gpu decoding
[21:15] <nevcairiel> technically, avcodec does, you need some user code to make it work
[21:15] <Zeranoe> nevcairiel: Is it automatically used, or is there special way to test it?
[21:15] <nevcairiel> which the ffmpeg application does not implement
[21:16] <nevcairiel> you could run vlc, it uses it
[21:16] <Zeranoe> nevcairiel: Is there a way to test it on the command line?
[21:16] <nevcairiel> is mplayer considered command line? =P
[21:17] <Zeranoe> nevcairiel: is it only available in other applications?
[21:17] <nevcairiel> gpu decoding is not useful for transcoding because the gpu decoders are so slow in comparison
[21:17] <nevcairiel> the ffmpeg applications dont support it
[21:18] <Zeranoe> nevcairiel: Interesting, so it only really helps with playing a steam? 
[21:18] <cone-290> ffmpeg.git 03rogerdpack 07master:a50049a197a5: dshow: use standardized raw pixel format lookup

[21:18] <cone-290> ffmpeg.git 03Michael Niedermayer 07master:f7b7f021e528: Merge remote-tracking branch 'rdp/combined'
[21:19] <llogan> "hdyc col". not very descriptive.
[21:20] <Zeranoe> nevcairiel: How many encoders support CPU threading in FFmpeg?
[21:20] <nevcairiel> no idea, i dont encode much
[21:22] <J_Darnley> Wasn't a flag added to codecs to state whether they supported frame and/or sliced threads?  Does ffmpeg -codecs tell you?
[21:28] <J_Darnley> Answer: My (slightly) old ffmpeg doesn't but a search shows 59 matches in 39 files.
[21:35] <llogan> ubitux: how is the adventure?
