[08:44:05 CEST] <lillian> hey everyone
[11:46:31 CEST] <nashgul> hi all
[11:47:28 CEST] <nashgul> i'm recording with my webcam and the alsa input, but there is a delay of 2 seconds between the 2 inputs, how can i adjust  that delay?
[11:48:28 CEST] <nashgul> my command is: ffmpeg -f v4l2 -i /dev/video0 -i alsa hw:1,0 -f ogg -q:v 7 -q:a 7 -ar 44100 -ac 2 output.ogg
[11:49:07 CEST] <nashgul> really the video is delayed
[11:53:13 CEST] <nashgul> :-D, sorry, -itsoffset , forget my question
[12:15:51 CEST] <Fjorgynn> yeah
[13:39:35 CEST] <RobertNagy> I have an issue where I have two wav files, 0.wav and 1.wav which I can concat using the concat demuxer without issue. However, I want to concat in a browser (aac, mp3, aac). However, I have found no way to encode the segments to either these formats and still be able to concatenate them without distortion.
[13:40:35 CEST] <RobertNagy> I have tried to make sure that 0.wav and 1.wav start and end on 1024/960 sample count boundaries.
[13:41:04 CEST] <RobertNagy> But still I can't concat them seamlessly, even with cat (aac) or ffmpeg-concat (opus)
[13:41:15 CEST] <RobertNagy> haven't even gotten as far as trying in a browser
[13:41:26 CEST] <RobertNagy> is this even possible or am I aiming for a lost cause?
[19:29:39 CEST] <edoceo> I'm merging two audios, into a overlay in a grid.  But when I'm done there is no audio.  I can see the audio stream in the media but it's silent
[19:30:05 CEST] <edoceo> I'm using the amerge filter: [0:a][1:a]amerge=inputs=2[aout]' -map '[aout]' -ac 2
[19:36:00 CEST] <razzledazzle> Hey guys can I ask a question related to transcoding but not directly related to ffmpeg?
[21:55:30 CEST] <edoceo> It seems that the -ss and -itsoffset values on inut are not used by the amix and amerge filters in a filter complex?
[21:55:48 CEST] <edoceo> How can I get the audio to seek as well as the video in this grid merge?
[22:05:01 CEST] <Mavrik> evenin
[22:29:02 CEST] <edoceo> evenin?  I'm not finding anything about that in man or google
[23:39:30 CEST] <anoop_r> hi
[23:40:12 CEST] <anoop_r> with all your support i had succesfully created a transcoder using ffmpeg+c#
[23:40:55 CEST] <anoop_r> if anybody have windows + .net 4.5 and kind heated enough to test my software please
[23:41:16 CEST] <anoop_r> http://www.qfs.mobi/f2403835
[23:41:26 CEST] <anoop_r> check here
[23:42:17 CEST] <anoop_r> if any part of this violating any thing of ffmpeg please inform me i am happy to correct
[23:42:54 CEST] <anoop_r> you can provide feedback to keepitsimplepltd at yandex.com
