[09:28] <cone-717> ffmpeg.git 03Michael Niedermayer 07master:08b22c0ea536: Merge remote-tracking branch 'qatar/master'
[09:29] <michaelni> mateo`, do you want to review "1007 18:22 To FFmpeg devel (1.2K) 
[09:30] <michaelni> or should i just apply them ?
[09:30] <michaelni> they are of course tested ...
[10:24] <cone-717> ffmpeg.git 03Carl Eugen Hoyos 07master:d24da748c308: Add H.264 fourcc GAVC for GeoVision cameras.
[11:38] <durandal_1707> why frame_count starts from 0?
[11:38] <durandal_1707> bah
[12:04] <TheFluff_> what are you, a lua programmer?
[12:09] <durandal_1707> lua programmers counts from 1?
[12:09] <ubitux> yes
[12:10] <ubitux> array indexing starts at 1 iirc
[12:11] <Daemon404> yep.
[12:12] <durandal_1707> i am ex-lua programmer so i think lavfi should start counting from 1
[12:15] <Daemon404> durandal_1707, vf_lua.c time?\
[12:15] <durandal_1707> nope i'm using AVExpr and exposing link->frame_count via it
[12:16] <Daemon404> because everybody loves typing several kb of shit on the cmd line
[12:18] <durandal_1707> nobody comes with patch that gives alternative
[12:21] <durandal_1707> and what would vf_lua.c do if you can't call filter within filter
[12:21] <durandal_1707> of if filter can't control filtergraph
[12:22] <durandal_1707> and i guess recreating filtergraph resets all frame counts thus you are damned
[13:07] <ubitux> Daemon404: you can write the filtergraph in a file and you know it
[13:07] <ubitux> it's just more convenient on the cli 95% of the time
[13:08] <durandal_1707> what filtergraph in while?
[13:08] <ubitux> parse error
[13:09] <durandal_1707> can you give example of such filtergraph in file?
[13:10] <ubitux> i was refering to -filter_script and -filter_complex_script durandal_1707 
[13:11] <durandal_1707> i use that, and that is just command line
[13:11] <ubitux> yeah but i was talking to Daemon404 
[13:12] <durandal_1707> ok let me paraphrase what he said: because everybody loves typing several kb of shit in file
[13:13] <ubitux> maybe i misunderstood everything :)
[13:22] <Daemon404> [12:07] <@ubitux> Daemon404: you can write the filtergraph in a file and you know it
[13:22] <Daemon404> i actuall did not.

[16:54] <durandal_1707> if nobody wants to review telecine patches its time now (an no reviews like 'ok if tested' are not reviews)
[16:55] <durandal_1707> i will also make big changes to MA* file
[16:55] <cone-717> ffmpeg.git 03Luca Barbato 07master:c0de9a23c708: prores: Reject negative run and level values

[16:56] <durandal_1707> michaelni: are you gonna push qp?
[17:11] <cone-717> ffmpeg.git 03Michael Niedermayer 07master:dfb89fee2d2b: doc/codecs: document skip_alpha
[17:48] <durandal_1707> ubitux: why is decimate changing pts when it does not change time_base ?
[17:48] <ubitux> maybe it's broken
[17:49] <durandal_1707> it should change time_base?
[17:49] <durandal_1707> well it could... but there is no need ....
[17:50] <durandal_1707> also the fps thing seems fishy, filter just eats random frames...., why care about fps
[20:06] <cone-717> ffmpeg.git 03Timothy Gu 07master:a55e813e5394: doc/codecs: Cosmetics in the flags2 description
[20:06] <cone-717> ffmpeg.git 03Timothy Gu 07master:db4a677433a6: doc/codecs: Remove no longer existing options
[20:06] <cone-717> ffmpeg.git 03Timothy Gu 07master:1fdae1017c5b: doc/codecs: Add ignorecrop
[20:06] <cone-717> ffmpeg.git 03Timothy Gu 07master:024bf3a1c2d3: doc/codecs: Add missing mpeg2 aac profiles
[20:10] <ubitux> durandal_1707: maybe we should just divide the pts by the same frame count divider..
[20:10] <ubitux> in decimate
[20:11] <durandal_1707> why?
[20:11] <durandal_1707> test with audio where first pts != 0
[20:11] <durandal_1707> and where pts are not increasing one by one
[20:12] <durandal_1707> it probably should be rescaled once time_base is changed too
[20:12] <durandal_1707> but i do thing its not required
[20:12] <durandal_1707> *think
[20:12] <ubitux> mmh
[20:13] <durandal_1707> well if you want each frame have same duration than yes, you need to change time_base too
[20:13] <durandal_1707> and rescaled every pts
[20:15] <ubitux> but where is the pts adjustement supposed to happen?
[20:18] <durandal_1707> pts are a, b, c, d, e; when you drop for example c, you rescale all other frames to take same timeframe, which current code does, but it resets pts to 0 thus causes async
[20:22] <ubitux> yes i understand the problem with the current solution
[20:22] <ubitux> but i don't understand how you address the issue by simply dropping the pts negociation
[20:26] <durandal_1707> i don't :)
[20:27] <durandal_1707> i could pick min and max pts between frames and interpolate using them...
[20:27] <ubitux> durandal_1707: then maybe try frame->pts *= outlink->frame_rate
[20:28] <ubitux> ah er
[20:28] <ubitux> well, pick the correct multiplie
[20:28] <ubitux> r
[20:40] <ubitux> frame->pts = frame->pts * (dm->cycle - 1) / dm->cycle;  something like this probably
[20:53] <durandal_1707> that cant work
[20:55] <cone-717> ffmpeg.git 03Timothy Gu 07fatal: ambiguous argument 'refs/tags/n1.1.7': unknown revision or path not in the working tree.
[20:55] <cone-717> Use '--' to separate paths from revisions
[20:55] <cone-717> refs/tags/n1.1.7:HEAD: doc/codecs: Add missing mpeg2 aac profiles
[22:30] <durandal11707> michaelni: can this be solved at all?
[22:30] <durandal11707> i see vf_fps code doesn't do anything similar
