[21:53] <cone-159> ffmpeg.git 03Michael Niedermayer 07master:126927c58e16: avcodec/exr: mark gama option as experimental / unsupported
[22:28] <Snowleaksange> seems image2 format doesnt work with custom AVIOContext?  find_image_range() seems to rely on local filename, and the AVFMT_NOFILE flag is set
[22:29] <ubitux> michaelni: no need to review 5/5, i'll drop it
[22:30] <ubitux> i think it might cause some issue with pad filter
[22:30] <ubitux> i'm not able to find a way of triggering the issue, but i'm not comfortable with that change anymore
[22:30] <ubitux> i'll apply the 4 others though, th
[22:30] <ubitux> thx
[22:31] <michaelni> ok
[22:33] <michaelni> Snowleaksange, it should work with a custom URLProtocol, though beware of ABI/API compatibility issues if you use that
[22:38] <Snowleaksange> ah i didnt know about urlprotocols
[22:39] <Snowleaksange> any recommended resource?  can i replace all my old aviocontext with urlprotocols?
[22:45] <cone-159> ffmpeg.git 03Martin Storsjö 07master:0bacfa8d3771: rtmpproto: Check the buffer sizes when copying app/playpath strings
[22:45] <cone-159> ffmpeg.git 03Michael Niedermayer 07master:996fffbbb3c2: Merge commit '0bacfa8d37710b904897e7cbeb8d6f96fbf75e2e'
[22:45] <Snowleaksange> hmm yeah doesnt really look usable
[22:45] <Snowleaksange> ok im just going to directly to all the codec libs myself
[22:45] <Snowleaksange> basically reimplemented ffmpeg
[22:48] <Snowleaksange> shouldve done this long ago
[22:48] <Snowleaksange> you guys should just stop developing ffmpeg
[22:48] <Snowleaksange> its never gonna be more than trojan horse
[22:49] <Snowleaksange> no way to fix the code
[22:49] <Snowleaksange> burn it
[23:09] <compn> did i miss something ? 
[23:09] <compn> great troll.
[23:20] <ubitux> ah, question for the timeline in case of phase filter
[23:20] <ubitux> currently, when the filter is in "enable mode", it have to have a 1-frame delay
[23:20] <ubitux> this might not be what the user is expecting
[23:21] <ubitux> the other way is to always keep a reference to the previous frame
[23:21] <ubitux> so it can be reuse immediately for when the filter is enabled again
[23:21] <ubitux> that sounds better right??
[23:21] <ubitux> -?
[23:27] <michaelni> id say yes
[23:30] <ubitux> ok
[23:47] <ubitux> #define DIFF(a, as, b, bs) (t = ((*a - b[bs]) << 2) + a[as << 1] - b[-bs], t * t)
[23:47] <ubitux> pdif += DIFF(nptr, ns, nptr, ns);
[23:47] <ubitux> i just realized how awesome this is
[23:47] <ubitux> :)
[23:58] <cone-159> ffmpeg.git 03Clément BSsch 07master:362ab940fc5d: avfilter/phase: add comment on the context cached frame.
[23:58] <cone-159> ffmpeg.git 03Clément BSsch 07master:687119aa9d2d: avfilter/phase: do not pass the whole context to analyze_plane().
[23:58] <cone-159> ffmpeg.git 03Clément BSsch 07master:8de600de553a: avfilter/phase: avoid a memcpy per frame.
[23:58] <cone-159> ffmpeg.git 03Clément BSsch 07master:69d72140accb: avfilter/phase: add timeline support.
