[03:05] <Slant|UW> Can anyone else get gst-python to work?
[03:05] <Slant|UW> that is, the documentation part of the compile?

[04:04] mxpxpod ([email protected]) left irc: "To quit or not to quit.. wait... was that a question?"
[04:25] <Slant|UW> Anyone awake at all?
[04:36] <thaytoo> Slant|UW: yo
[04:36] <thaytoo> I haven't tried gst-python for a little while
[04:36] <Slant|UW> Hey.
[04:36] <Slant|UW> It is failing in the xmlto segment.
[04:38] mxpxpod ([email protected]) joined #gstreamer.
[04:40] <Slant|UW> Will gst-python work with 0.7/0.8 (since that's due out in a few days?)
[04:41] <thaytoo> there's been work to keep it up to date, yeah
[04:42] <thaytoo> jdahlin and thomasvs have been hacking on it
[04:42] <thaytoo> I don't know enough about the docs build to help you
[04:43] <thaytoo> you can do --disable-docs, of course
[04:43] <thaytoo> (in configure)
[04:44] BBB ([email protected]) joined #gstreamer.
[04:44] <BBB> ds-work: da?
[04:44] Action: Slant|UW nods.
[04:45] <thaytoo> BBB: good morning
[04:46] <BBB> hi
[04:46] Action: BBB has MPEG playing :)
[04:46] <BBB> but it requires some bad changes
[04:46] Action: BBB looks for thomasvs, ds and company
[04:46] <thaytoo> I haven't seen them pop up recently
[05:15] steveb__ ([email protected]) joined #gstreamer.

[05:17] coredump ([email protected]) joined #gstreamer.
[05:19] <coredump> Would anybody like to explain how one would get tags from an audio file through GStreamer (i.e. the state of the tags API)
[05:19] <coredump> or refer me to a document which would do the same
[05:19] Action: coredump is quite lost
[05:22] <BBB> ds: your asm patch doesn't really compile
[05:22] mathrick ([email protected]) left irc: Read error: 60 (Operation timed out)
[05:22] <BBB> coredump: build a pipeline, attach to the have_tags signal, iterate and wait
[05:22] <BBB> once you get the signal, dispose the pipeine
[05:22] <BBB> that's all
[05:22] <ds> BBB: ok, odd
[05:23] <BBB> that 
[05:23] <BBB> I still get the same GENERAL_REGS compile error
[05:23] <BBB> and one more:

[05:25] <ds> i may have screwed up making the patch
[05:25] <BBB> maybe...
[05:26] <BBB> one more thing, ds
[05:26] <BBB> I want to change the default scheduler from optomega to basicgthread
[05:26] <BBB> opinions?
[05:27] <BBB> and yes, I've got a good reason ;)
[05:27] <BBB> after that, I'll work on fixing up matroska tags/seeking, adding seeking to quicktime and fixing alsa in the gnome-volume-contgrol
[05:27] <BBB> and I'd love some work on a 5:1-to-stereo converter, too
[05:28] <BBB> but that won't be me :/
[05:28] mathrick ([email protected]) joined #gstreamer.
[05:29] <coredump> BBB: Do you mean the found-tag signal?
[05:30] <BBB> uhm
[05:30] <BBB> probably
[05:30] <BBB> I'm bad at signal names
[05:31] <ds> BBB: isn't the default scheduler opt?
[05:31] <ds> BBB: I'm ok with basicgthread, as soon as it passes the regression tests :)
[05:31] <BBB> bla
[05:32] <BBB> it plays MPEG
[05:32] <coredump> hehe
[05:32] <coredump> ok
[05:32] <coredump> thanks
[05:32] <BBB> is that a nice new feature?
[05:32] <BBB> np :)
[05:32] <BBB> and opt fails in more places than basic
[05:32] <BBB> so...
[05:32] <BBB> please, please, basic?
[05:32] <BBB> (just fix basic if it fails anywhere)
[05:33] <ds> I suggested it a few days ago, btw
[05:33] <ds> I got no response
[05:33] <BBB> I'm in favour
[05:33] <BBB> I just didn't notice
[05:33] Action: BBB is offline too much
[05:33] <ds> everone was gone
[05:34] <BBB> he :)
[05:34] <BBB> and you expect responses then? :p

[05:41] <BBB> hm
[05:41] <BBB> gst-rec still works
[05:41] Action: BBB whees
[05:46] Action: BBB needs to work on overlay during capture
[05:49] <spyder482> what did you fix/b0rk

[10:19] <alley_cat> audioscale ! audio/x-raw-int,rate=48000 ! alsasink for me
[10:19] <alley_cat> rate depends on what your card prefers, mine works with 44100 and 48000
[10:20] <sxpert_work> ok, in fact, I changed the 'osssink' to 'alsasink' in my program, and I don't have anymore problems :D
[10:20] <sxpert_work> apparently, the latest alsa does the job
[10:21] <sxpert_work> ok, my sound-server app works, but rhythmbox doesn't... (grrr)

[17:13] <alley_cat> what's the pipeline gst-player uses?
[17:13] <alley_cat> doesn't even work with osssink anymore now, i'd like to see if i can reproduce it with gst-launch
[17:16] <thomasvs> it's not easy/even possible from the cmd line
[17:17] <thomasvs> but there's "player" in examples/gstplay
[17:17] Nick change: jonathang_ -> jonathang
[17:18] <alley_cat> ok, gives the same error
[17:19] <thomasvs> what's the error ?
[17:19] <alley_cat> ** ERROR **: internal error: cannot schedule get to loop in multi-loop based group
[17:19] <alley_cat> aborting...
[17:22] <thomasvs> jdahlin: care to take a shot at this ?
[17:22] <thomasvs> alley_cat: what happens with --gst-scheduler=basicgthread ?
[17:22] <jdahlin> thomasvs: sure
[17:22] <jdahlin> alley_cat: do you have a testcase?
[17:23] <alley_cat> works with basicgthread
[17:23] <teuf> isn't gst-player known to be broken currently ? I think BBB told that a few days ago
[17:23] <alley_cat> jdahlin: examples/gstplay/player <whatever media file i try>
[17:24] <jdahlin> ** (process:12171): WARNING **: libgstplay: failed initializing pipeline, error: Could not link video output thread (cs and balance)
[17:24] <jdahlin> that's what I get
[17:24] <thomasvs> jdahlin: you need ffcolorspace
[17:24] <jdahlin> thomasvs: can I change to colorspacE?
[17:25] <thomasvs> hm, yeah, you can try, but it's probably going to fail
[17:25] <thomasvs> hm, unless you take an audio file first
[17:25] <thomasvs> currently working on rearranging cvs for ffmpeg though
[17:25] <thomasvs> alley_cat: maybe file a bug report, so people can look at it as soon as ffmpeg is buildable
[17:26] <jdahlin> thomasvs: does ffcolorspace have any patent issues?
[17:27] <thomasvs> jdahlin: the code, no.  fmpeg, yeah.
[17:27] <thomasvs> jdahlin: which is why I'm convincing ronald to rip out only the colorspace code
[17:27] <jdahlin> thomasvs: cool
[17:28] Action: thomasvs wishes patch could change/create new files with given permissions
[17:29] <jdahlin> i386/fdct_mmx.c:16:20: common.h: No such file or directory
[17:30] <thomasvs> jdahlin: as I said - I'm working on it, step by step :)
[17:30] <thomasvs> I'll let you know when you can test
[17:31] <jdahlin> ok
[17:33] Nick change: markey|run -> markey
[17:33] <alley_cat> current gst-ffmpeg worked for me after i removed the gst-libs/ext/ffmpeg/ffmpeg directory and reran autogen.sh
[17:34] <jdahlin> I checked out a clean dir
[17:38] Nick change: mxpxpod -> mx|shower
[17:39] arana ([email protected]) joined #gstreamer.
[17:41] <bitshifter> My GObject knowledge is somewhat limited, but I've now seen multiple plugins (e.g. spider, mad) that have a dispose method only (and no finalize) and where the dispose method is written as if it could only be called once (e.g.  g_free(element->foo); without setting element->foo to NULL afterwards)
[17:42] <bitshifter> while Mathieu Lacage's GObject paper says that ::dispose might be invoked  multiple times
[17:42] <bitshifter> so I'm wondering if this is simply an oversight or if plugins are special in that there is no real-world case where dispose is run twice
[17:43] kmaraas ([email protected]) left irc: Client Quit
[17:44] luis_ ([email protected]) joined #gstreamer.
[17:45] <teuf> bitshifter: wasn't there something about dispose methods not too long ago on the mailing list ?
[17:46] <alley_cat> hmm, alsasink stops working after some seconds of playback
[17:46] <bitshifter> teuf: possible, I suck at remembering things :)  I'll check, thanks
[17:48] spyder482 ([email protected]) left irc: Nick collision from services.
[17:48] Nick change: arana -> spyder482
[17:48] <bitshifter> teuf: you're right. Wingo posted a case where dispose could be called multiple times. Doesn't look like anyone bothered to fix the plugins though :)
[17:48] <thomasvs> bitshifter: in any case, patches setting stuff to NULL are apreciated
[17:48] <thomasvs> bitshifter: seems not too hard, so we'd appreciate someone going through it !
[17:48] <jonathang> i noticed that when using the adder element in gstreamer 0.6.4 with the opt scheduler, the first channel gives an eos after some seconds and so isn't played anymore.
[17:49] <jonathang> but when using a basic scheduler (basicgthread for example), it works
[17:49] <thomasvs> jonathang: sounds like correct behaviour no ?
[17:49] <thomasvs> if the first channel eos's, it's supposed to be removed
[17:50] <jonathang> yes, except the first channel's length is about 3 mùinutes
[17:50] sjoerd ([email protected]) left irc: Remote closed the connection
[17:50] <jonathang> and with gstreamer cvs, it absolutely doesn't work
[17:50] <bitshifter> thomasvs: okay, I'll have a look at that then
[17:50] <jonathang> with opt scheduler, gives me nothing
[17:51] <thomasvs> jonathang: could be, I'm hoping to look at the example sometime next week
[17:51] <jonathang> and the other just schedulers just crashes
[17:51] <jonathang> thomasvs, i think it's only in the adder because i tested without the volenv and such

[18:40] teuf ([email protected]) left irc: "Client exiting"
[18:40] <thomasvs> mxpxpod: then you probably didn't install the gconf schemas ?
[18:46] <jdahlin> thomasvs: ffmpeg is not supposed to build yet right?
[18:51] <thomasvs> jdahlin: I didn't tell you yet today that it did, did I ? :)
[18:51] Action: jdahlin can't recall
[18:52] <thomasvs> trust me, you'll be the first to hear the savage cry with positive content
[18:52] <jdahlin> lovely
[19:00] <luis_> thomasvs: oh, BTW, I think that answers my question. :)
[19:04] <thomasvs> luis_: about avi ?
[19:04] <thomasvs> luis_: hm, depends :)
[19:09] <luis_> thomasvs: well, when I run gst-launch-ext, it says it can't build a pipeline because it is missing ffmpegdecall, but when I run configure, ffmpeg doesn't show up as either something that will or won't build
[19:09] kwm ([email protected]) joined #gstreamer.
[19:09] <thomasvs> ah, yeah
[19:10] <thomasvs> we removed ffmpeg from gst-plugins and moved it to a different module
[19:12] Action: thomasvs tries a make distcheck on the new gst-ffmpeg module
[19:13] <mxpxpod> thomasvs: ok, so the schema is installed, but it's not showing up in gconf editor
[19:13] <thomasvs> mxpxpod: huh, that's weird
[19:13] <thomasvs> here it shows up fine
[19:13] <mxpxpod> hmm
[19:13] <thomasvs> can you run test-gconf in the gst-libs/gst/gconf dir ?
[19:14] <danb> the site gives a 404 for the language bindings page
[19:14] <thomasvs> danb: yeah, I need to add those again
[19:14] <thomasvs> danb: will do so soon
[19:14] <danb> anyone know why (or want to fix it :D )?
[19:14] Action: thomasvs sees a bunch of stuff actually compiling
[19:14] <thomasvs> danb: yeah, soon :)
[19:14] <danb> thomasvs: ETA? or better yet, can you point me to some docs for gst-python?
[19:15] <thomasvs> danb: better yet.
[19:15] <thomasvs> danb: I'll give you the man who is working on it RIGHT NOW.
[19:15] <danb> or should i just look in the gst-python tarball
[19:15] <thomasvs> jdahlin: you have a customer
[19:15] Action: jdahlin hides
[19:15] <danb> oo
[19:15] <danb> lol
[19:15] <jdahlin> danb: you can find it in cvs, there is no web page yet
[19:15] <thomasvs> ===================================================
[19:15] <thomasvs> gst-ffmpeg-0.7.1.1.tar.gz is ready for distribution
[19:15] <thomasvs> ===================================================
[19:15] <thomasvs> schweet
[19:15] <thomasvs> this setup will be a classic example in opensource textbooks for years to com
[19:16] <jdahlin> thomasvs: commit commit commit!
[19:17] <danb> jdahlin: cool. is cvs my best bet for using gst-python?
[19:17] <jdahlin> danb, at the moment unfortunately

[20:38] <alley_cat> yes
[20:38] <alley_cat> just did it
[20:38] <alley_cat> but i was also able to compile gst-ffmpeg, so ... :)
[20:39] <LeRoutier> ok, do you have imlib2 installed ?
[20:41] <alley_cat> no
[20:42] <alley_cat> imlib, but not imlib2
[20:42] <LeRoutier> oh, ok
[20:42] <LeRoutier> perhaps IMLIB provides the m4 macro that gst-ffmpeg uses to detect imlib version
[20:43] <LeRoutier> alley_cat, could you please run this : grep -r AM_PATH_IMLIB /usr/share/aclocal* | wc -l
[20:44] thomasvs ([email protected]) joined #gstreamer.
[20:44] <alley_cat> yes, imlib.m4 has that macro
[20:44] <LeRoutier> re thomasvs
[20:44] <LeRoutier> alley_cat, ok, so that is why it works for you and not for me
[20:45] <LeRoutier> thomasvs, could you please add a imlib.m4 into gst-libs/ext/ffmpeg/common/m4 (or whatever m4 dir is for ffmpeg local copy) to fix imlib2 detection ?
[20:47] <thomasvs> LeRoutier: I will, but I'm working on the new module, not the old one
[20:47] <LeRoutier> thomasvs, i know, i have the error with both
[20:47] <LeRoutier> with gst-ffmpeg.new : aclocal: configure.ac: 550: macro `AM_PATH_IMLIB' not found in library
[20:47] <thomasvs> LeRoutier: yeah, but I think it's not needed to have imlib
[20:47] <thomasvs> LeRoutier: in any case, copy the m4 manually for now, until we decide how to properly do it
[20:48] <LeRoutier> well, there is the pkg-config way as imlib2 provides a .pc file

[21:56] <thomasvs> luis_: why ?
[21:56] <Company> gst_caps_get_structure should take an unsigned int :/

[21:57] <luis_> well, configure said it couldn't find the .pc
[21:57] <luis_> but I seem to have gotten the plugin anyway
[21:58] Action: luis_ shrugs
[21:58] <Company> gst_caps_get_size should return an unsigned int, too
[21:59] <ds-work> I think integers should be int unless there's a compelling reason not to be
[22:00] teuf ([email protected]) left irc: "Client exiting"
[22:00] <Company> i thought uint is faster?
[22:00] <Company> i remember reading somewhere to make i always unsigned for for loops

[22:06] yippi ([email protected]) joined #gstreamer.
[22:07] <ds-work> Company: no, but it doesn't really matter
[22:08] <ds-work> Company: it should be int32
[22:08] <Company> ds-work: and i think arguments should be in the format they're supposed to be in - so a value should be unsigned if it's never < 0
[22:09] <ds-work> Company: no,
[22:09] <ds-work> Company: the parameters are integers with a limited range
[22:09] <ds-work> that limited range just happens to not include negative numbers
[22:09] <yippi> i need to chat with somebody about mpeg and dvd related plugins.  does anybody have time to chat about this?
[22:10] <ds-work> Company: because by the same argument, they generally can't be above MAX_INT, so they shouldn't be unsigned int
[22:11] <Company> ds-work: yes, but if you use unsigned, you can't forget to check for < 0
[22:11] teuf ([email protected]) joined #gstreamer.
[22:12] <ds-work> so unsigned int is a crutch for bad programming?
[22:13] <Company> no
[22:13] <Company> it's a help
[22:14] <Company> but index functions and size functions are always unsigned
[22:14] <Company> even if those values are in the range [0, MAX_INT]
[22:18] Action: bitshifter thinks unsigned int is good in many cases because an 'off-by-minus-one' bug is often hard to find or detect, whereas a 'off-by-G_MAXUINT' will usually cause havoc
[22:24] <Company> i think not checking a value read somewhere if it's really >= 0 is worse
[22:24] <Company> for an example see the BMP exploit in the win200 source tarball
[22:30] <thaytan> yippi: good morning
[22:30] <ds-work> why not just audit the code for correct range checking?
[22:31] <Company> why not just use uints?
[22:31] <ds-work> because unsigned ints add complexity at the user-visible level
[22:32] Nick change: kh_zZz -> kh_out
[22:32] <yippi> hello, thaytan
[22:32] <Company> user-visible level?
[22:32] <yippi> isn't there anybody who can chat with me for a few minutes about mpeg and dvd related plugins?
[22:32] <ds-work> API level
[22:32] <thaytan> yippi: what are your questions about?
[22:33] <Company> so we should just convert all uints to ints?
[22:33] <Company> and add lots of bounds checking code?
[22:33] <ds-work> depends on the usage
[22:33] <yippi> i need to find out a few things.  1) Is there a plugin that supports MPEG 2, but does not support other MPEG versions? 
[22:33] <yippi> 2) What plugins, specifically are needed in order to play a DVD?
[22:33] <ds-work> Company: if it's really just an integer confined to a range, it should be int
[22:34] <Company> ds-work: i want to compile all our stuff with -Wsign-compare
[22:34] <ds-work> Company: in that case, it's a lot simpler to use ints everywhere
[22:35] <ds-work> Company: because mixing uint and int is what causes problems with -Wsign-compare
[22:35] teuf ([email protected]) left irc: Read error: 54 (Connection reset by peer)
[22:35] <Company> but bounds checking is better?
[22:35] <thaytan> yippi: 1) not unless there is one in ffmpeg somewhere. mpeg2dec is the normal element, and it also does MPEG1
[22:35] <thaytan> it doesn't do mpeg4, however
[22:36] teuf ([email protected]) joined #gstreamer.
[22:36] <ds-work> Company: you have to check bounds anyway
[22:36] <Company> the compiler generates a warning if you have a comparsion problem, it doesn't generate one if you forget to check for < 0
[22:36] <thaytan> 2) DVD playback is still incomplete, but I've been testing using dvdnavsrc ! mpegdemux name=demux .video_00 ! mpeg2dec ! \
[22:36] <thaytan> mpeg2subt name=sub ! xvimagesink demux.subtitle_stream_1 ! sub.subtitle \
[22:36] <thaytan> demux.private_stream_1_0 ! { queue ! a52dec ! esdsink }
[22:37] <thaytan> that mpegdemux element will get replaced by a dvddemux derived from it, but the pipeline should stay substantially the same
[22:37] <ds-work> Company: and you want to bother with all the crap associated with unit vs. int just to get a lousy compiler warning?
[22:37] <Company> ds-work: yes
[22:37] <Company> ds-work: because people get bitten by it often enough
[22:38] <ds-work> Company: why not just do an audit?  it's necessary anyway
[22:38] <Company> ds-work: and there aren't really many comparions between uint and int if you use the right type
[22:38] <Company> ds-work: because you can still overlook stuff in an audit
[22:39] <ds-work> Company: and compilers have false positives.  so what
[22:40] Zeenix ([email protected]) joined #gstreamer.
[22:40] <ds-work> and you have to add code to convince the compiler not to give a warning in legal cases
[22:40] <Company> yes
[22:40] <yippi> thatytan:  that was a bit too technical for me.  could you just list which plugins are needed (or will be needed once the work is finished) to play DVD's?
[22:40] <Company> but the compiler finds every problem
[22:41] <ds-work> so would an audit.  An audit, even, would find problems that a compiler couldn't possibly detect
[22:41] <Company> an audit does not find every problem
[22:41] <thaytan> yippi: sorry :-) they're all in that pipeline: dvdnavsrc, dvddemux (based on mpegdemux) mpeg2subt (subtitles) a52dec, and output elements ie xvimagesink and osssink and friends

[22:51] <mathrick> ho
[22:51] <Company> ha
[22:52] <yippi> thaytan: right.  which of the DVD plugins would require IP licenses to use, if any?  I know the mpeg ones do.
[22:52] <yippi> thaytan: also, which of the plugins do you mention are still under development?
[22:53] <thaytan> yippi: I don't know. The legality of open source DVD players has always been questionable
[22:53] <thomasvs> any brave soul here who wants to try the gst-ffmpeg.new module ?
[22:53] <thaytan> especially under US law
[22:53] <mathrick> thomasvs: probably me. what is it?
[22:54] <thaytan> the dvdnavsrc component relies on libdvdnav to do the reading, which relies on other libraries, which usually include libdvdcss for cracking css keys
[22:54] <thaytan> I don't know what the status of that is in US law
[22:54] <thomasvs> mathrick: the improved version of our ffmpeg stuff, guaranteed to build or your money back
[22:55] <thaytan> AFAIK there's no problems with demuxing mpeg or reading the subtitle formats, but IANAL
[22:55] <thomasvs> mathrick: well, if you have hte deps :)
[22:55] <mathrick> thaytan: i think it was recently made legal, or at least not criminal to use
[22:55] <thomasvs> I wish ronald would come around
[22:55] <mathrick> thomasvs: ok, will give it a ride :)
[22:55] <teuf> thomasvs: I'm giving it a try
[22:55] <yippi> thaytan: which of the dvd plugins are still under development, and when do you think they will be done?
[22:56] <teuf> thomasvs: fails on aclocal: configure.ac: 550: macro `AM_PATH_IMLIB' not found in library
[22:56] <teuf> aclocal: configure.ac: 555: macro `AM_PATH_SDL' not found in library
[22:56] <teuf> even if I set ACLOCAL_FLAGS to a path where it's available
[22:56] <thaytan> yippi: dvdnavsrc, dvddemux and mpeg2subt primarily
[22:56] <thaytan> and Martin Soto is working on the dxr3 versions of the subtitler, a52dec and mpeg2 decoder
[22:57] <thaytan> a52dec needs a bit more loving too, I think
[22:57] <yippi> when do you think that the plugins under development will be done, roughly?
[22:57] <mathrick> teuf: that's what LeRoutier was encountering too, in old gst-ffmpeg
[22:57] <thaytan> hopefully before I get back from europe at the end of april
[22:57] <thaytan> it could be earlier, I'm not sure
[22:58] <yippi> is the only potential IP issue with DVD related to the css keys?
[22:59] <yippi> does it also use MPEG?
[22:59] <thaytan> and patents on the mpeg format itself
[22:59] <thaytan> it handles mpeg as data bytes, but knows nothing about the actual format
[22:59] <teuf> mathrick: thomasvs: adding a ${ACLOCAL_FLAGS} to ffmpeg autogen.sh helps
[22:59] <thaytan> are there issues with the DVD vobs and menuing? I don't know
[22:59] <yippi> which of the plugins in the DVD stack you mentioned above does mpeg decoding?
[23:00] <yippi> the dvddemux?
[23:00] <thaytan> mpeg2dec
[23:00] <thaytan> dvddemux does too
[23:00] <thomasvs> teuf: yeah, but I think I'm going to remove imlib and sdl from our ffmpeg stuff, since we don't use it anyway
[23:00] <thaytan> it splits the mpeg stream up into the component encoded video/audio/subtitles
[23:00] <thaytan> then mpeg2dec decodes to raw video frames
[23:00] <thaytan> a52dec decodes surround sound to audio frames, etc
[23:01] <teuf> thomasvs: ACLOCAL_FLAGS is needed anyway, for example for people who have pkg-config installed in a different prefix than gstreamer (assuming ffmpeg uses pkgconfig)
[23:01] <yippi> will dvddemux replace mpeg2dec in the pipeline?
[23:01] <yippi> or will they both be used?
[23:01] <thaytan> no, it will replace mpegdemux
[23:01] <yippi> is mpeg2dec also used in the dvd pipeline?
[23:01] <thaytan> *nod*
[23:02] <thomasvs> teuf: yeah, I know
[23:02] <yippi> i see.  you didn't list it in your list above.  though i notice you have it in the pipeline 
[23:02] <thaytan> yippi: oops! 
[23:02] <thaytan> yes, it should also have been in there
[23:02] <yippi> so the pipeline will be dvdnavsrc->dvddemux->mpeg2dec->mpeg2subt?
[23:03] <thaytan> yup
[23:03] <yippi> what does a52dec do?
[23:03] <thaytan> also with dvddemux->a52dec->audiosink there too
[23:03] <mathrick> <thaytan> a52dec decodes surround sound to audio frames, etc
[23:03] <mathrick> :)
[23:04] <yippi> does a52dec have IP issues?
