  • ffmpeg does not record audio exactly after setting duration with -t

    25 janvier 2016, par rudyshihhh

    I tried to record the audio of web page by ffmpeg and it worked well with the comment as below.

    ~$ ffmpeg -f alsa -ac 2 -i pulse output5.wav

    and could get the audio file which was saved in my local device. However, recording could not work properly after I added the parameter "-t" to limit the duration of recording. For example, if I set -t 20, the saved file only 0 or 20 KB but the comment without -t can get about 4MB. Is there any problem with my comment ? or Is there any other manner to record the audio by ffmpeg in limited time ?

    ~$ ffmpeg -f alsa -ac 2 -i pulse -t 20 output5.wav

  • Unable to record and stream screen with ffmpeg in RPI 2

    31 décembre 2015, par aug born

    I am using RPI 2 and trying to record a screen and stream it on udp using ffmpeg. I tried the following lines

    ffmpeg -f video4linux2 -i video="screen-capture-recorder":audio="Stereo Mix (IDT High Definition" -vcodec libx264 -preset ultrafast -tune zerolatency -r 10 -async 1 -acodec libmp3lame -ab 24k -ar 22050 -bsf:v h264_mp4toannexb -maxrate 750k -bufsize 5000k -f mpegts udp ://239.0.1.23:1234

    But I am getting error.

    The ffmpeg program is only provided for script compatibility and will be removed in a future release. It has been deprecated in the Libav project to allow for incompatible command line syntax improvements in its replacement called avconv (see Changelog for details). Please use avconv instead.

    I also tried x11grab but still getting the same error.

  • ffmpeg replace part of audio file with looped audio gives queued buffers

    1er décembre 2015, par user1202648

    I am quite new to ffmpeg and I am trying to replace a part of a first audio file with another second file. The second file can be too short, so some sort of loop should exist.

    After some research I came up with the following command arguments and it gives me the output as long as I only do one replacement. But I would like to do multiple replacements. So any help on what I am doing wrong ? Any suggestions/remarks on the way of working are also very welcome.

    (Any typos in the commands below can be ignored, I generate the command by script and for ease of use I simplified the names.)

    Works (One replacement) :

    "ffmpeg.exe" -y -i "first.wav" -i "second.wav" -filter_complex "[1:a][1:a][1:a]concat=n=3:v=0:a=1,asetpts=PTS-STARTPTS[replaceBase];[0:a]atrim=0:3,asetpts=PTS-STARTPTS[partA];[replaceBase]atrim=0:2,asetpts=PTS-STARTPTS[replaceA];[0:a]atrim=start=5,asetpts=PTS-STARTPTS[partB];[partA][replaceA][partB]concat=n=3:v=0:a=1[aout]" -map "[aout]" Out.wav

    Works Not (Multiple replacements) :

    "ffmpeg.exe" -y -i "first.wav" -i "second.wav" -filter_complex "[1:a][1:a][1:a]concat=n=3:v=0:a=1,asetpts=PTS-STARTPTS[replaceBase];[0:a]atrim=0:3,asetpts=PTS-STARTPTS[partA];[replaceBase]atrim=0:2,asetpts=PTS-STARTPTS[replaceA];[0:a]atrim=5:4,asetpts=PTS-STARTPTS[partB];[replaceBase]atrim=0:2,asetpts=PTS-STARTPTS[replaceB];[0:a]atrim=start=6,asetpts=PTS-STARTPTS[partC];[partA][replaceA][partB][replaceB][PartC]concat=n=4:v=0:a=1[aout]" -map "[aout]" Out.wav
