[17:17] <burek> one noob question.. if I want to use 1 ffmpeg git cloned on my machine to produce several different builds (one gpl, another non-free), how can I specify in the configure script to put all object/binary/make files into separate directory for each build?
[17:23] <Compn> set the bin dir ?
[17:23] <Compn> ./configure --help | grep -i bin
[17:24] <burek> --bindir=DIR             install binaries in DIR [PREFIX/bin] <--- that?
[17:24] <burek> well, that installs binaries into some dir
[17:24] <burek> I need all *.o files to put into /obj/
[17:27] <Compn> oh
[17:27] <Compn> no clue
[17:27] <Compn> yeah that 
[17:29] <burek> would it be enough, for example, to just cd into the obj/ directory and run ../configure ...?
[17:33] <Compn> sounds like a user question :P
[17:33] Action: Compn is helpful!
[17:33] <burek> :beer: :)
[17:33] <Compn> sounds like you want 'to build ffmpeg out of tree'
[17:33] <Compn> try google that
[17:36] <burek> that's it :) thanks a lot! :)
[18:39] <CIA-17> ffmpeg: 03Carl Eugen Hoyos 07master * r3dafde0b96 10ffmpeg/libavcodec/ (cscd.c version.h): 
[18:39] <CIA-17> ffmpeg: Simplify camstudio decoding and fix odd 16bit decoding.
[18:39] <CIA-17> ffmpeg: Fixes ticket #1220.
[18:47] <CIA-17> ffmpeg: 03Stefano Sabatini 07master * r46eba43e0e 10ffmpeg/libavfilter/buffersink.h: lavfi/buffersink: fix header inclusion guard name
[19:30] <burek> Compn, do you know maybe how can I compile libx264 in some tmp directory without make install and then tell ffmpeg to find what it needs for libx264 in that tmp directory?
[19:30] <burek> something like ./configure --enable-libx264=/my/tmp/dir/x264 :)
[20:40] <burek> also, is it more appropriate (if I'd like to compile 32bit ffmpeg on 64bit machine) to use "--arch=i386" or "--cc='gcc -m32'"
[20:41] <Daemon404> --extra-cflags and --extra-ldflags
[20:42] <burek> i see, it's better to use those 2 instead of -cc, but does --arch set up all that automatically?
[20:43] <Daemon404> that was in response to the part about a local libx264
[20:43] <burek> oh, ok :) thanks :)
[21:31] <burek> hm, I hit a wall now.. I've built libx264 as 32bit lib/bin and it works on 32bit machine
[21:32] <burek> I've also built bare ffmpeg (just ./configure) as 32bit bin and it also works on 32bit machine
[21:32] <burek> but trying now to build ffmpeg+libx264 as 32bit bin gives me this:
[21:33] <burek> http://pastebin.com/kKpuGtwn
[21:33] <burek> shortly, undefined reference to `x264_encoder_open_124'
[21:33] <burek> :S
[21:49] <michaelni> burek, you compile ffmpeg against the headers for the x264 you link it too ? aka they are matching ?
[21:49] <michaelni> both version 124 ?
[21:49] <burek> I figured I've put --arch=i386 which I guess is invalid.. I put --arch=x86 and doing make again
[21:50] <burek> both x264 and ffmpeg are from latest git if that's what you are asking :)
[21:59] <burek> woo hoo it works \o/ :)))))))))
[22:01] <burek> or not :/
[22:01] <burek> ./ffmpeg: error while loading shared libraries: libx264.so.124: cannot open shared object file: No such file or directory
[22:01] <burek> back to the lab..
[22:09] <Daemon404> protip: have the shared lib somewhere ffmpeg can see
[22:10] <burek> I figured it's looking in usr/local/lib and /usr/lib but I've used --prefix=/custom/dir to install compiled x264
[22:10] <burek> I'm trying static build now and if it works, that will be ok too :)
[22:11] <burek> it would be cool if I could just speed up make like not to build everything, just the very basic set fo formats, codecs, etc
[22:13] <Daemon404> burek, you can enable/disable anything you want
[22:13] <Daemon404> configure --help
[22:13] <Daemon404> also, this may be mroe suited to #ffmpefg
[22:13] <Daemon404> er
[22:13] <Daemon404> #ffmpeg
[22:13] <burek> ok, sorry
