[01:17] <teratorn> hey, can anyone recommend a video editing library based on ffmpeg?
[01:22] <Compn> avidemux works pretty well
[01:22] <Compn> if thats what you are looking for
[01:23] <teratorn> well, a library
[01:23] <teratorn> we want to implement our own GUI frontend
[01:23] <Compn> heh
[01:24] <teratorn> of course we can use ffmpeg directly, but was hoping for something higher level and geared to editing
[01:24] <Compn> most editors use libavcodec and libavformat and make their own programs using those to open and decode files
[01:25] <Compn> since those can be built as libs
[01:25] <teratorn> I suppose it's relatively trivial to cut a video directly, yeah
[01:25] <teratorn> transition effects are another thing
[01:25] <Compn> i dont recall any editor libs
[01:25] <Compn> there might be one and i just dont know of it
[01:25] <Compn> wait around :)
[01:25] <teratorn> cool thx anyway :)

[01:29] <CIA-17> ffmpeg: h264: assembly version of get_cabac for x86_64 with PIC (v4)
[01:29] <CIA-17> ffmpeg: This adds a hand-optimized assembly version for get_cabac much like the
[01:29] <CIA-17> ffmpeg: existing one, but it works if the table offsets are RIP-relative.
[01:29] <CIA-17> ffmpeg: Compared to the non-RIP-relative version this adds 2 lea instructions
[01:29] <CIA-17> ffmpeg: and it needs one extra register.
[01:29] <CIA-17> ffmpeg: There is a surprisingly large performance improvement over the c version (more

[02:22] <CIA-17> ffmpeg: fix swr_convert buffering of packed audio
[02:22] <CIA-17> ffmpeg: swr_convert is not properly buffering packed input audio when the
[02:22] <CIA-17> ffmpeg: output is not large enough, and when resampling is not actually needed
[02:22] <CIA-17> ffmpeg: (same samplerate and no SWR_FLAG_RESAMPLE).
[02:22] <CIA-17> ffmpeg: buf_set() is only handling the first channel and leaving the others as-is.
[02:22] <CIA-17> ffmpeg: Sample program to reproduce the problem is here https://gist.github.com/2431768

[02:22] <CIA-17> ffmpeg: Revert "h264: assembly version of get_cabac for x86_64 with PIC (v4)"
[02:22] <CIA-17> ffmpeg: This broke compilation on darwin, revert until a better solution is found.
[02:22] <CIA-17> ffmpeg: This reverts commit a812b599b504b39a8021827da89d5e23fb361cc9.
[02:38] <funman> i thought only darwin/x86 was problematic, not x86_64
[02:42] <iive> funman: the commit in questing is 1 hour old, you can see the description above.
[04:25] <funman> ah it changed x86 too

[17:29] <ods15> any way to tell gcc that "(const int[]){1,2,3}" should go in text segment and not in data?... if I put it on a seperate line it works, but not within an expression :/
[17:32] <michaelni> ods15, probably best to ask gcc devels
[17:34] <ods15> it's alright, I gave up, two lines it is... means I need to declare all the arrays first, and then I intialize the big array which uses them all
[17:35] <ods15> yey, now this file has zero data/bss size
