[03:04:42 CET] <ltrudeau> Anyone know in what version of RealVideo was directional intra prediction introduced? (I was told pross might know this)
[03:06:17 CET] <ltrudeau> Basically I'm backtracking directional Intra, and worked my way back all the way to RealNetworks
[03:06:59 CET] <ltrudeau> I'm assuming that if they proposed it in H.26L it's because they might already have in RV
[03:17:27 CET] <Lynne> ltrudeau: https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/ituh263dec.c#L463
[03:17:32 CET] <Lynne> rv10 version 3 probably
[03:18:45 CET] <Lynne> if h263_aic is true then https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/h263.c#L220 gets called which seems to do something directional
[03:19:02 CET] <ltrudeau> Lynne: Thanks for answering
[03:19:41 CET] <ltrudeau> Lynne: I was not precise enough in my question, I'm looking for H.264 style directional intra pred (angles like 45 degrees)
[03:21:45 CET] <Lynne> I think looking for such directional intra in realvideo is a red herring, that doesn't sound likely
[03:38:07 CET] <Lynne> no, nothing in either 263 or rv40, the closest directional thing I could find is dc prediction in 263 could either use top or left block through a simple heuristic
[03:42:17 CET] <Lynne> ltrudeau: found it https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/rv34.c#L972
[03:45:34 CET] <Lynne> but the codec's based on h264, so it probably wasn't the first

[12:30:11 CET] <durandal_1707> michaelni: you still havent fixed s16le in wav?
[12:32:37 CET] <michaelni> durandal_1707, no, after reading your mail where you claim i stole money i decided i will not look into this
[12:32:52 CET] <michaelni> this is not funny
[12:35:37 CET] <kierank> durandal_1707: wtf
[13:00:39 CET] <kierank> durandal_1707: you should retract your statement
[13:00:41 CET] <kierank> even if it is a joke
[15:03:41 CET] <JEEB> durandal_1707: the format is officially called "3D Audio" so I guess that's why the sony person put that in the name https://mpeg.chiariglione.org/standards/mpeg-h
[15:37:39 CET] <durandal_1707> michaelni: not really my problem or file or commit or bug

[20:36:36 CET] <kierank> hmmm how is this guy fuzzing so well
[21:11:05 CET] <jamrial> kierank: he's testing muxers and filters, which google isn't
[21:11:10 CET] <jamrial> it's free real state :p
[21:11:48 CET] <kierank> I gather that
[21:11:52 CET] <kierank> but wondering how he's doing it
[21:11:56 CET] <jamrial> he's also using the cli with random command line options that make no sense in combination, instead of a reduced set of api functions in a simple c file
[21:12:02 CET] <kierank> ok
[21:12:11 CET] <jamrial> so that may also be a factor
[22:02:51 CET] <BBB> how did cehoyos manage to fly to the mentor summit for $90? o_O
[22:03:16 CET] <durandal_1707> he is superman
[22:03:23 CET] <nevcairiel> i feel like google should pay for transport
[22:03:31 CET] <BBB> they provide stipends
[22:03:53 CET] <jamrial> where was the summit? maybe he just took a train or two
[22:04:33 CET] <nevcairiel> its always in the US i believe
[22:04:49 CET] <jamrial> huh, no idea then
[22:05:10 CET] <nevcairiel> maybe he only requested the remainder after using up the stipend
[22:15:08 CET] <kierank> jamrial: it was in munich
[22:15:51 CET] <jamrial> train, then
[22:20:53 CET] <BBB> ah, that explains
