[00:29:20 CET] <cone-086> ffmpeg 03Stephen Hutchinson 07master:e003a5345285: avisynth: update headers against AviSynth+
[05:01:30 CET] <cone-007> ffmpeg 03Michael Niedermayer 07master:354db19ff44c: avcodec/h264: Remove bits_per_raw_sample hacks
[05:44:46 CET] <cone-007> ffmpeg 03Philip Langdale 07master:21175d8586d3: avcodec/nvenc: Add support for H.265 encoding
[07:22:44 CET] <relaxed> I'm getting a build failure with "allcodecs.c:(.text+0x7b6): undefined reference to `ff_nvenc_h265_encoder'". Is it related to 21175d8586d3 ^^^ ?
[07:38:03 CET] <jamrial> yes. that commit broke compilation on builds without nvenc
[07:38:12 CET] <jamrial> fate is about to be 100% red, haha
[07:38:36 CET] <jamrial> i think a configure line should fix it
[07:38:55 CET] <relaxed> ok, just wanted to give a heads up.
[07:39:30 CET] <jamrial> thanks
[07:49:44 CET] <Zeranoe> It looks like the latest commit does not compile "libavcodec/allcodecs.c:231: undefined reference to `ff_nvenc_h265_encoder'"
[07:50:14 CET] <jamrial> i know, i'm on it
[07:51:54 CET] <cone-007> ffmpeg 03James Almer 07master:7c4910758ac2: configure: add missing dependency for nvenc_h265
[07:52:07 CET] <jamrial> there, should be fixed
[08:01:21 CET] <Zeranoe> jamrial: Thank you very much for the swift responce 
[08:03:10 CET] <jamrial> no problem
[08:03:18 CET] <cone-007> ffmpeg 03James Almer 07master:23e1303c0add: avcodec/nvenc_h265: add missing version bump and changelog entry
[10:16:46 CET] <himangi> how can I test to see if there in no AV desync.. any parameters?
[10:20:30 CET] <himangi> michaelni: Are there any parameters that quantify AV desync?
[11:46:55 CET] <michaelni> himangi, you watch a video and see with your eyes and ears if audio and video is in sync, like if you use the matrixbench video do you hear the gunshots when you see the muzzleflash or is it a second off ?
[11:47:53 CET] <himangi> michaelni: yeah I did that.. perception wise it seems fine to me.. I have sent in a new patch
[11:49:21 CET] <himangi> however there is an AV value that shows up while playing.. I guess it represents the desync
[11:52:46 CET] <michaelni> the displayed number is wont change with increasing AV desync from wrog timestamps
[11:52:53 CET] <michaelni> wronNg
[12:28:18 CET] <cone-007> ffmpeg 03Ronald S. Bultje 07master:b8e36690e8d9: lavu/frame: move av_frame_copy_props() up in the file.
[12:28:19 CET] <cone-007> ffmpeg 03Ronald S. Bultje 07master:589a6042ea80: avutil: make AVFrameSideData buffers ref-counted.
[14:46:23 CET] <BtbN> huh, when was the nvenc h265 merged? I just wanted to add the missing changelog entry to the preparation patch, but is's already merged.
[14:47:40 CET] <Daemon404> [07:02] < cone-007> ffmpeg James Almer master:23e1303c0add: avcodec/nvenc_h265: add missing version bump and changelog entry
[14:47:45 CET] <Daemon404> i guess lol
[14:48:08 CET] <rcombs>  <cone-007> ffmpeg Philip Langdale master:21175d8586d3: avcodec/nvenc: Add support for H.265 encoding
[14:49:08 CET] <BtbN> I realy need to get some hardware to mess with that stuff.
[15:51:49 CET] <cone-007> ffmpeg 03Himangi Saraogi 07master:b020a25df234: avcodec/j2kenc: Initialize variable to silence compiler warnings
[17:41:15 CET] <cone-007> ffmpeg 03Stephen Hutchinson 07master:3a6df0b4bb58: avisynth: ifdef to avoid implicit function declaration errors
[18:47:17 CET] <cone-007> ffmpeg 03Michael Niedermayer 07master:bdcd36a4c81c: swscale/output: Fix undefined shifts
[20:38:07 CET] <himangi> michaelni: should I keep the ts_mode option with a default 1 or do away with it?
[20:38:28 CET] <michaelni> himangi, you can drop the option if you like
[20:45:21 CET] <cone-007> ffmpeg 03Stephen Hutchinson 07master:1492118c9d3c: avisynth: drop support of AviSynth 2.5
[20:45:22 CET] <cone-007> ffmpeg 03Stephen Hutchinson 07master:9f91c5198f17: doc: remove the reference to supporting AviSynth 2.5
[22:25:00 CET] <LigH> Hello.
[22:27:11 CET] <LigH> There is a Blender guide to use the Blender frame server with a shell script that pulls ppm images via wget in a loop and stuffs one after another into a pipe to feed ffmpeg as video encoder. This seems not to work under Windows.
[22:27:37 CET] <LigH> But ffmpeg also seems to support a text file with a list of images to use as input sequence.
[22:27:51 CET] <LigH> Unfortunately, this may only support local files.
[22:28:22 CET] <LigH> I wonder if it may be possible to mod ffmpeg to support a list of HTTP URLs as well?
[22:34:40 CET] <IlIlIlIlIlIlI> would it be possible for ffmpeg/avfilter to support a "shell_pipe" filter, piping the PCM (os specified format) through a shell command?
[22:35:10 CET] <IlIlIlIlIlIlI> I'd use it e.g. with some of the yet-unported SoX filters, for starters
[22:35:35 CET] <IlIlIlIlIlIlI> (or* specified format)
[22:36:05 CET] <LigH> Possibly with two instances: ffmpeg | sox | ffmpeg
[23:32:33 CET] <cone-007> ffmpeg 03Philip Langdale 07master:21adb9964e2a: avcodec/nvenc: Need a separate class for each encoder
[23:33:14 CET] <nevcairiel> shared classes causing crap again .. i wonder if we couldnt fix the code that breaks there all the time instead =p
[23:35:20 CET] <wm4> why does C code need classes
[23:35:20 CET] <philipl> jamrial: Thanks for fixing the dependency problem.
[23:35:49 CET] <nevcairiel> wm4: avclasses, you know!
[23:35:58 CET] <philipl> Everyone loves classes.
[23:36:04 CET] <philipl> Sorry for the fireworkss.
