[10:48] <wodim> hello, i have a dvd with a "making of" (lots of short clips) but there are only a few .VOB files. The big ones contain a lot of clips/chapters/whatever. The dvd is supposed to be navigated with the dvd menu. how can i know what the offsets and lengths are?
[11:14] <Xeta> Is there any easy way to apply Replaygain headers (which are in the m4a audio file) in ffmpeg to normalize audio?
[11:41] <wodim> I use -chapter x-x and whatever I choose for x it ends up playing the same chapter. Any idea?
[11:41] <wodim> wrong chan
[17:02] <coalado> Hi.
[17:03] <coalado> Do you know any way to estimate the actual "bitrate/quality" of an audio file? Let's say a file has been encoded to mp3_64kbit and than to aac_192 kbit. I'd like to find a way to estimate the actual "quality"
[17:03] <sacarasc> "Shit"
[17:04] <coalado> is this an answer to my question?
[17:04] <sacarasc> Yes.
[17:04] <sacarasc> 64kbps MP3 isn't great, except maybe for voice only.
[17:04] <sacarasc> Then another lossy conversion is just going to make it worse.
[17:04] <superware> no shit
[17:05] <coalado> I did not ask if 64kbps is shit or not.
[17:05] <sacarasc> You could run it through a spectrograph and see where it caps out and things, but proper analysis is beyond me.
[17:06] <coalado> sacarasc:  that's the answer I was looking for :)
[17:22] <superware> any idea why AVStream->avg_frame_rate is {0,0} for h264 network streams? how can I reliably get frame rate?
[19:31] <bmhm> hi. I'd like to send gst-omx's encoded video to ffserver. Anyone knows how to do that?
[21:31] <bmhm> Used pipes so far.
[22:37] <kris_> so I compiled ffmpeg from git (just a blind make install without reading much) - it compiled and installed fine, but I ran into errors with libx264 vcodec. I ran ffmepg -formats and didn't see it listed - is there an option I need to tick to enable libx264 at build time?
[22:38] <znf> ./configure --help ? ^^
[22:39] <osmodiar> kris_: ffmpeg -codecs would be the one that shows it.
[22:39] <osmodiar> -formats is for containers.
[22:39] <kris_> is this it? its from an old 2008 post on gogole "./configure --enable-libx264 --enable-gpl --enable-pthreads"
[22:39] <kris_> osmodiar: oh :/
[22:39] <kris_> I seem to have h264 but not x264 :/
[22:40] <JEEB> yes, libx264 is a separate library
[22:40] <JEEB> you need --enable-gpl and --enable-libx264 after you have built it yourself (or if it is new enough in your repositories, installed the development package for it)
