  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • using ffmpeg to record highest resolution offered by Facetime cameras (mac)

    15 juin 2018, par user1361529

    I am using the following code successfully to record a video feed from my mac

    ./ffmpeg -f avfoundation -framerate 30  -i "default" out.mp4

    This however seems to be recording video at the lowest resolution of 320x200

    My camera supports the following resolutions :

    [avfoundation @ 0x7ff7b2800000] Supported modes:
    [avfoundation @ 0x7ff7b2800000]   1280x720@[1.000000 30.000000]fps
    [avfoundation @ 0x7ff7b2800000]   640x480@[1.000000 30.000000]fps
    [avfoundation @ 0x7ff7b2800000]   320x240@[1.000000 30.000000]fps

    I tried manually specifying the resolution using both -s and -video_size but that seems to just scale up the low res video.

    How do I get ffmpeg to pick my 1280x720 resolution ?

    thanks

  • How to Re-stream SDP as RTSP (at smaller resolution) using ffmpeg

    6 avril 2018, par mikeyb976

    I have an existing rtp stream (720p) via SDP which I would like to restream as RTSP as 360p resolution.

    I’ve been able to restream the sdp as rtsp successfully, using the command below :

    ffmpeg -protocol_whitelist file,udp,rtp -re -i mike1.sdp -c:v libx264 -s 640x360 -f rtsp -muxdelay 0.1 rtsp ://[username] :[password]@127.0.0.1:1935/live/myStream

    and my local wowser streaming server recognises the stream source as rtsp. I can also playback the video using a small c# project that implements vlc.dotnet.wpf player control. I just inject the rtsp url into it, and it loads.

    What I don’t know, is How can I create the rtsp stream so that it is at a lower resolution of 360p. (the source is 720p)

    Any help is much appreciated

  • ffmpeg reverse video resolution after compression

    30 août 2018, par Mehran

    I’m trying to compress a video to mp4 format with ffmpeg.

    With scale filter :

    cmd = "-i, "+in+" -vf scale=480:-2,setsar=1:1, "+out;

    Or as simple as this :

    cmd = "-i, "+in+" "+out;

    If I try this command, the outPut will be fine in many players like potPlayer(win) or mxPlayer(android), But in some players like kmPlayer.v3(win) it’s stretched. with or without scale filter.

    I tried the same video compression with Handbrake so I find out there is nothing wrong with my player.

    The result is the same with all videos that I compressed with ffmpeg library

    And there is another problem which is more annoying, the outPut video resolution gets reversed. for Example :

    Input : w1280 h720

    Output : w720 h1280

    I googled a lot but I found nothing.
