[00:00] <WindozeNT> I'm trying to cut out parts of a video with -ss and -t, but FFMPEG isn't honoring the -t and encodes past it.
[00:42] <khaosmarmoset> protip: run your script with bash -x :)
[01:11] <ArunC> Hi, is there a way to rotate/transpose a AVFrame programmatically using libavfilter?
[01:13] <khaosmarmoset> I'm gonna go out on a limb and say "yes". https://www.ffmpeg.org/doxygen/2.4/vf__rotate_8c.html http://www.ffmpeg.org/doxygen/0.9/vf__transpose_8c-source.html
[01:51] <katayana> how do I play playlists (streaming, m3u) with ffplay?
[02:03] <Sevanoo> Hello
[02:03] <Sevanoo> I have some problems with ffserver
[02:04] <Sevanoo> i think there is an bug in the new versions of ffmpeg (ffserver)
[02:40] <khaosmarmoset> go on
[05:17] <mk_> Can someone tell me what this means, and how i'm able to fix this issue? "[abuffer @ 042989e0] Value inf for parameter 'time_base' out of range [0 - 2.14748e+009][abuffer @ 042989e0] Unable to parse option value "(null)" as sample format"
[15:44] <knotwurk> say, is there some kinda trick to converting something that's riff (little-endian) xvid/mp3 .avi file?
[15:44] <knotwurk> as in, something that doesn't mess with the bitrate/format too much
[15:45] <knotwurk> i've tried it several different ways and when i play it on the tv it's kind of studdering at parts
[15:50] <khaosmarmoset> so you're saying you have mp3 inside your riff file and you want to convert it into an avi?
[15:52] <khaosmarmoset> riff as a format is so vague that it's hard to say what's inside without having a look.
[15:52] <khaosmarmoset> (anyway, I know nothing knotwurk, so please to wait for people with more bits in the brein.)
[15:53] <knotwurk> this is what the file command shows it as:  "RIFF (little-endian) data, AVI, 720 x 536, 25.00 fps, video: XviD, audio: MPEG-1 Layer 3 (stereo, 48000 Hz)"
[15:53] <knotwurk> for some reason the tv thing doesn't play it, and it has something to do with the riff/little-endian thing
[15:53] <khaosmarmoset> and what does your tv support?
[15:53] <knotwurk> oh a whole bunch of formats, usually there's no problem w/ avi/mpeg
[15:54] <khaosmarmoset> maybe the bitrate is too high for your tv.
[15:55] <knotwurk> yeah maybe i should go back to the manual
[15:55] <khaosmarmoset> or if it doesn't like the xvid then I think you're going to need to re-encode.
[15:56] <knotwurk> yeah that's what i've been doing
[15:56] <knotwurk> it might be a good idea to just reencode part of it so i can experiment
[15:56] <khaosmarmoset> nod
[15:56] <khaosmarmoset> I gotta go. happy debugging!
[15:56] <knotwurk> cya
[16:48] <c_14> knotwurk: what does ffprobe say about the file?
[16:53] <knotwurk> c_14: http://dpaste.com/278E0G3
[16:59] <c_14> You could try converting to non-xvid mpeg4...
[17:00] <c_14> Not sure why the TV would stutter on that though.
[17:14] <knotwurk> hm, mpeg2video looks better for some reason
[17:29] <kaotiko> hi
[17:41] <knotwurk> hello
[17:52] <EDevil> When providing ffmpeg with a URL where the content is, is it capable of taking advantage of HTTP ranges to seek the file and locate the moov atom?
[22:35] <edman007> Hi, anyone have any experiance with dvdauthor? Why does it not add chapters where I ask? I encoded my video with ffmpeg, and then dvdauthor tried to read it and adds chapters at 0, about 60s, and then repeats the 60s time for all chapters (which makes for a broken dvd)
