[00:59:42 CEST] <gcl5cp> how can i overlay a image only the first 3 seconds?
[01:02:04 CEST] <gcl5cp> overlay take all video, is possible overlay just X seconds?
[05:43:42 CEST] <happyfr0gg> Is this PPA compatible with Ubuntu 14.04??? --> http://ubuntuforums.org/showthread.php?t=2219550&s=0dfc0a2cfb9cf02bcca07ba4455cc8b2&p=13101922#post13101922
[05:43:58 CEST] <happyfr0gg> I am referring to the CLI for download and install.
[05:45:46 CEST] <BtbN> That ppa doesn't exist anymore.
[06:49:33 CEST] <jookiyaya> how do i convert burn-in subtitles on video = text subtitle file?
[06:49:54 CEST] <jookiyaya> how do i convert burn-in subtitles on video = text subtitle file? big reward
[06:59:25 CEST] <BtbN> You mean subtitles that are burnt into the picture?
[06:59:57 CEST] <BtbN> If so, that's not possible.
[07:00:16 CEST] <BtbN> Find someone to watch the video and type them.
[07:02:11 CEST] <jookiyaya> yes
[07:02:44 CEST] <jookiyaya> shouldn't it be possible using OCR
[07:11:13 CEST] <BtbN> Good luck with that.
[17:07:14 CEST] <Fyr> guys, are there options for ALAC?
[17:08:22 CEST] <Fyr> I want to set maximum compression. =/
[17:10:19 CEST] <Fyr> or for flac
[18:08:03 CEST] <WhiteBunny> Anyone here ?
[18:08:22 CEST] <WhiteBunny> I have an out of area question to ask if that's OK ?
[18:08:48 CEST] <WhiteBunny> Do anyone know where i can find this icons -> http://i.imgur.com/DB8ZHtf.png
[18:50:50 CEST] <hid> hi
[18:51:08 CEST] <hid> has anyone ever recorded the audio card output?
[18:51:37 CEST] <hid> i have 2 devices: 0 and 1
[18:52:10 CEST] <c_14> alsa? pulse?
[18:52:20 CEST] <hid> but ffmeg -f alsa -i hw:0 out.wav (or 1) does not wrk
[18:53:05 CEST] <c_14> https://trac.ffmpeg.org/wiki/Capture/ALSA
[18:53:29 CEST] <hid> yes i followed this tutorial
[18:53:31 CEST] <hid> c_14:
[18:55:20 CEST] <hid> this is 'arecord -L' command http://pastie.org/private/buio9q5ylaurodlc9yoeq
[18:56:02 CEST] <c_14> You seem to have pulse, try using the pulse input device
[18:56:50 CEST] <hid> c_14: you mean like `ffmeg -f pulse -i hw:0 out.wav' ?
[18:57:09 CEST] <c_14> https://ffmpeg.org/ffmpeg-devices.html#pulse
[18:57:32 CEST] <c_14> you can get the device name with pactl list or something iirc
[18:57:37 CEST] <c_14> pactl list sources
[19:02:14 CEST] <the_gamer> hi there, i am using the docu from https://trac.ffmpeg.org/wiki/Encode/MPEG-4 but with qscale:v 1 ffmpeg answers: [NULL @ 0x7f0525a52be0] Unable to find a suitable output format for '1' 1: Invalid argument
[19:02:20 CEST] <the_gamer> why is that?
[19:04:12 CEST] <the_gamer> http://www.pasteall.org/58475
[19:05:06 CEST] <c_14> that ':' should be a ' '
[19:05:11 CEST] <c_14> by -acodec
[19:05:38 CEST] <the_gamer> great, thanks a lot, sry for that
[19:12:34 CEST] <hid> c_14: thank you very much :)
[19:13:22 CEST] <hid> this finally works :)
[19:30:36 CEST] <hid> c_14: do you know if it is better to record from the speakers output or the headphones output?
[19:30:59 CEST] <c_14> If it's output to both it probably doesn't matter.
[19:49:14 CEST] <hid> c_14: it seems that the option -sample_rate 44100 has no effect on the output file
[19:49:29 CEST] <hid> it still records with 48kHz
[19:49:36 CEST] <hid> do you know why?
[19:56:03 CEST] <DragonsLord> Hi all
[19:56:32 CEST] <DragonsLord> can someone suggest me a player I can use in order to proceed by milliseconds
[19:56:37 CEST] <DragonsLord> or frame by frame?
[19:56:59 CEST] <DragonsLord> I need to put very exact timing to remove adv
[19:59:56 CEST] <Anoia> VLC allows frame stepping iirc
[20:00:52 CEST] <DragonsLord> thank you Anoia
[20:01:04 CEST] <DragonsLord> but how can I detect on wich frame I am?
[20:08:13 CEST] <hid> hmmm it seems -ar works better than -sample_rate
[20:08:24 CEST] <hid> very interessant
[22:53:04 CEST] <edoceo> DragonsLord: the time indicator on VLC will show you the frame, but you have to change it's default display mode
[22:53:34 CEST] <edoceo> Usually it's HH:MM:SS.mmm - you can make it fffff/FFFFF like
[23:19:12 CEST] <DragonsLord> Thank you edoceo
[23:21:12 CEST] <DragonsLord> but my VLC is currently showing only HH:MM:SS
[23:21:14 CEST] <DragonsLord> no ms
[23:21:33 CEST] <DragonsLord> also time is acceptable
[23:21:38 CEST] <DragonsLord> but I need ms
[23:23:50 CEST] <hid> DragonsLord: did you try mplayer -fps 1
[23:25:01 CEST] <DragonsLord> it should be just fine to see milliseconds
[23:25:12 CEST] <DragonsLord> but I have some troubles with AVIdemux
[23:25:21 CEST] <DragonsLord> playing some MP4 videoes
[23:51:30 CEST] <BtbN> Oh my god, there aparently is a HLS JavaScript player, that on-the-fly remuxes mpegts to mp4 in JavaScript, so it can be played via MSE
