    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.

  • Stream part of the screen on linux

    1er juin 2014, par Boris Brodski

    How can I stream part of my screen using ffmpeg (avconv) on Linux ?

    I can record part of my screen :

    ffmpeg -f alsa -ac 1 -i pulse -acodec pcm_s16le -f x11grab -r 24 -s 100x200 -i :0.0+20,30 ...

    But trying to stream it adding

    -f rtp rtp://127.0.0.1:1234

    doesn’t work. ffmpeg starts to stream, but ffplay complains

    $ ffplay rtp://127.0.0.1:1234
    
[rtp @ 0xaf8026a0] Unable to receive RTP payload type 96 without an SDP file describing it

  • ffmpeg reduce image quality, NOT size [on hold]

    8 juin 2016, par ben_user6260230

    I successfully made a thumbnail from video using FFMPEG.

    ffmpeg -i 'video_location' -vf thumbnail,scale=160:120  -frames:v 1 'image_location.jpg'

    Is there any ’ffmpeg’ command to reduce image size without changing image scale ??

  • ffmpeg issue when recording screen+microphone+(music from file)

    9 juin 2016, par Taras Nikulin

    I’m trying to record using this command :

    ffmpeg -f avfoundation -pix_fmt nv12 -i "1:0" -r 30 -i monoSound.aac -filter_complex amerge=inputs=2 -vcodec h264 -qscale:v 0 -acodec aac -ab 128k -ac 1 -ar 44100 -async 30 outScreen.mp4

    I get such error :

    The following filters could not choose their formats: Parsed_amerge_0
    
Consider inserting the (a)format filter near their input or output.
    
Error configuring complex filters.
    
Input/output error

    If i rewove this "-async 30", then no errors appear in terminal. But on final video sound will disappear after couple seconds.
