[01:25] <BBB> ubitux: yes, fpel is uber-trivial
[02:31] <lindenle> In general how do i know what all i have to freee when using ffmpeg libraries? should i free wverything i alloc?
[02:31] <lindenle> i ask b/c i am looking at the muxing example and the pkt is never freed...so I am confused ;)

[10:11] <ubitux> michaelni: careful with "avformat: more correct printf format specifiers" if it gets applied
[10:11] <ubitux> there are a few problems with it
[10:12] <ubitux> like going from signed to unsigned
[10:12] <ubitux> and misc (probably harmless) nonsense
[10:13] <ubitux> such as:
[10:13] <ubitux> -            av_log(s, AV_LOG_WARNING, "skipping CAF chunk: %08X (%c%c%c%c)\n",
[10:13] <ubitux> +            av_log(s, AV_LOG_WARNING,
[10:13] <ubitux> +                   "skipping CAF chunk: %08"PRIX32" (%"PRIu8"%"PRIu8"%"PRIu8"%"PRIu8")\n",
[10:13] <ubitux> not sure that's relevant
[10:15] <nevcairiel> X is not standard?
[10:17] <ubitux> how so?
[10:17] <nevcairiel> %08"PRIX32"
[10:17] <nevcairiel> i figured at least X would be a standard printf thing

[16:46] <plepere> ubitux, can you explain to me how you use pmulhrsw to do  (result + offset) >> shift ?
[16:46] <plepere> please. :)
[16:48] <ubitux> iirc pmulhrsw is (A*B + (1<<14)) >> 15
[16:49] <ubitux> 1<<14 being for the rounding
[16:49] <ubitux>     pmulhrsw            m0, m5              ; (x*2048 + (1<<14))>>15 <=> (x+8)>>4
[17:03] <plepere> ok
[17:04] <plepere> so if I want to do result + (1<<5) >> 6
[17:05] <plepere> i do result<<9 with the multiplication
[17:06] <plepere> but then the second shift is too much...
[17:06] <ubitux> what's result?
[17:06] <ubitux> (x*1024 + (1<<14))>>15 <=> (x+16)>>5
[17:07] <ubitux> (x*2048 + (1<<14))>>15 <=> (x+8)>>4
[17:07] <plepere> I need to  do (x+32)>>6
[17:07] <ubitux> so i suppose... you want (x*512 + (1<<14))>>15 <=> (x+32)>>6
[17:07] <plepere> so basically 512
[17:07] <plepere> ok great. :D
[17:08] <plepere> thanks
[17:08] <ubitux> and guess what
[17:08] <ubitux> <<9 is *(1<<9)
[17:08] <ubitux> which is 512
[17:09] <plepere> so I guess I can skip on the operation ?
[17:09] <ubitux> yes
[17:09] <ubitux> pmulhrsw x, [pw_512]
[17:12] <plepere> hmmm
[17:14] <plepere> well it doesn't work. :p
[17:15] <ubitux> too bad
[17:15] <ubitux> >>> (1234+32)>>6
[17:15] <ubitux> 19
[17:15] <ubitux> >>> (1234*512 + (1<<14)) >> 15
[17:15] <ubitux> 19
[17:16] <ubitux> works for me
[17:16] <plepere> I believe you. :)
[17:18] Last message repeated 1 time(s).
[17:50] <plepere> ok it works.
[17:50] <plepere> the asm was right. it was all the rest that wasn't.
[17:50] <plepere> :)
[17:51] <plepere> thank you very much, ubitux 
[17:51] <ubitux> your welcome
[17:53] <ubitux> oh fuck diego is doing that space after cast insanity
[18:40] <llogan> michaelni: i set BadContent as read only if, somehow, they get smart and try to delete it
[19:05] <llogan> whats the max frame size for MPEG-4 part 2 video, level 1?
[19:09] <wm4>  [libav-devel] [PATCH 001/132] 
[19:09] <wm4> fun
[19:11] <ubitux> wm4: fun except the spaces after cast all over
[19:11] <wm4> as expected, the main problem are cosmetic issues
[19:12] <ubitux> Diego was asked to change it, but i'm pretty sure he won't, or only partially
[19:12] <ubitux> that was a really great idea to stack that much patches, ofc now for cosmetic issues..
[19:13] <ubitux> and knowing that the main reason for stacking that much patches was just a dick contest with Anton TEP makes me feel really sad
[19:14] <ubitux> apart from that they are intersesting changes hidden in the haystack
[19:15] <ubitux> 3-4 on the first ~35 afaict
[19:26] <wm4> ubitux: lol yes, they seem to love spamming large patch sets
[19:26] <wm4> repeatedly spamming them seems also to be the only thing that makes the libav-devel ML as active as the ffmpeg one
[19:26] <wm4> (ffmpeg has more discussion)

[21:57] <Case> michaelni: thanks, it seems like you fixed all the bugs I reported
[22:26] <lotharkript__> what should be the correct behavior for PTS/DTS from a M2ts file when the first PTS is really closed to the 33bit max? (for example, 1<<33 - 10). Should it be -10 or 1<<33 - 10 ? 
[22:26] <lotharkript__> for example, if I generate a file like this: ffmpeg -f s16le -ac 1 -i /dev/zero -af asetpts="PTS+95400/TB" -y  test.ts
[22:26] <lotharkript__> ffprobe will tell me the first pts is -42 s
[22:26] <lotharkript__> but if i do, ffmpeg -f s16le -ac 1 -i /dev/zero -af asetpts="PTS+47200/TB" -y test.ts
[22:26] <lotharkript__> the first PTS is positive and the PTS will never be negative and go back to 0, even after generating a 24h video.
