[07:15] <wm4> vdpau is broken in git master
[07:26] <wm4> and it works in libav git
[08:17] <wm4> ah, big WTF
[08:17] <wm4> struct Picture is supposed to alias struct H264Picture, but the field offsets don't match
[08:17] <wm4> so hwaccel_picture_private is "off"
[08:29] <wm4> found the issue, it was caused by libav refactoring
[08:55] <ubitux> wm4: but doesn't affect libav?
[08:55] <wm4> probably by coincidence
[08:55] <wm4> I sent a patch to libav-devel
[09:02] <nevcairiel> didnt michael fix such aliasings in various places
[11:07] <anshul_> wm4,the code should be cleaned up not to call av_log from a signal. What  would you suggest in How to tell the user that he has got seg-fault similar signal
[11:18] <wm4> anshul_: don't handle segfaults, that's just broken
[11:18] <wm4> for terminal, you could start a cleanup thread
[11:38] <anshul_> wm4,thanks

[13:03] <cone-171> ffmpeg.git 03Janne Grunau 07master:6a74ebc34dd3: float-dsp-test: do not use C99's predefined  __func__
[13:03] <cone-171> ffmpeg.git 03Michael Niedermayer 07master:3d04b1aab140: Merge remote-tracking branch 'qatar/master'
[13:24] <cone-171> ffmpeg.git 03Michael Niedermayer 07master:9d60527a1315: configure: fix direct symbol ref support detection
[16:34] <cone-706> ffmpeg.git 03Michael Niedermayer 07master:d3ed8a4d2b10: ffmpeg: try to avoid calling av_log() from sigterm_handler()
[17:19] <Case> I have one mp4 file that causes some trouble for ffmpeg.exe. Even a simple remux attempt gives "Assertion next_dts >= 0 failed at libavformat/movenc.c:620" message and Windows tells the exe crashed
[17:28] <ubitux> Case: open a ticket with a sample
[17:28] <ubitux> or you're here to fix it yourself?
[17:29] <Case> no. I don't understand about mp4 format. But I'm a bit hesitant to go make a ticket as the sample is over 1 GB and copyrighted video file. The cut versions work
[17:31] <JEEB> I would recommend grabbing L-SMASH and seeing what you can poke at it with the boxdumper tool
[17:31] <JEEB> it will output a human-readable dump of whatever's in the file
[17:40] <Case> --timestamp dump that outputs a list of DTS at least doesn't seem to have zeroes anywhere but for the first frame
[17:45] <Case> foobar2000's File Integrity Verifier says the file has garbage at the end
[17:52] <JEEB> well that assert just means that there's a DTS that's going backwards suddenly
[17:52] <JEEB> not sure what next_dts is
[17:52] <JEEB> but if it is the next dts value from the previous, that would mean it's not more or the same as the previous one
[17:52] <JEEB> thus making the time difference negative
[17:52] <wm4> but isn't this the encoder?
[17:52] <wm4> also av_assert is AFAIK for internal errors
[17:53] <JEEB> yeah, it should...
[17:53] <JEEB> can't say much without a sample :P
[17:53] <Case> it happens without encoding. ffmpeg -i file.mp4 -c:a copy -c:v copy test.mp4
[17:53] <JEEB> well, it is pushing the data through a demuxer and muxer at the very least
[17:53] <Case> it happens very close to the end so it may go to that garbage data
[17:53] <JEEB> and muxers are also sometimes called "encoders"
[17:53] <wm4> yeah, I meant muxing
[17:54] <JEEB> (as with lavf/movenc.c f.ex.)
[17:54] <wm4> that might mean ffmpeg.c is feeding the demuxer with invalid data
[17:54] <wm4> *muxer
[17:58] <Case> I modified that boxdumper tool and made it check for timecode errors. None found
