  • 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.

  • How I can receive MJPEG stream via RTSP with resolution more than 1080p

    21 septembre 2018, par chuchuchu

    There is a problem :
    When I get a video stream with a resolution of 1080 and below - everything is fine.
    But if I select a stream with a resolution higher than 1080 on the camera, an error occurs.
    FFMPEG :

    [mjpeg @ 0x7f5488003e40] [IMGUTILS @ 0x7f5494acb4f0] Picture size 0x0 is invalid

    If I open a stream in the player I get a disparate image :

    [mjpeg @ 0x7fd9f8043b20] error y=91 x=16
    
[mjpeg @ 0x7fd9f8043b20] error dc

    I repeatedly recompiled and reinstalled various versions of the ffmpeg, the problem is not solved.

    I suspect that there is a restriction for video stream over 1080p, but I can not find any description or solution.
    And I found next string in rfc "RTP Payload Format for JPEG" :

    The maximum width is 2040 pixels.

    but it is dated 1998. I know for certain that this stream on the RTSP receives in the resolution I need, but I can not understand how.

    Please, tell me the way to the solution. I’m using Ubuntu 16.04 amd64.
    Perhaps there is an alternative way to receive a rtsp-stream without using a ffmpeg ?? Since all ways known to me are using ffmpeg.

  • download hls from m3u8 file with a particular resolution with ffmpeg [on hold]

    22 octobre 2018, par C.J.

    hi i am a new member of this site after looking at this site for hours i found how to download HLS from a site and it works also. but one thing i could not find is if a particular site has available video in more than one resolution say 1280*720 and 1920*1080. so how do i tell FFMPEG to download 1280*720 and not 1920*1080. this is the code i tried.

    ffmpeg i "https://hsprepack.akamaized.net/videos/hotstarint/world/kwks6/1_2/master.m3u8?hdnea=st=1540178095 exp=1540179895 acl=/* hmac=ee2361306de510cf4f372c359b5ec21fd3d3b61d65b6f5e2f16259508e08c625" output.mp4

  • Standardizing many mp4 files into same resolution

    22 novembre 2018, par Cowfod

    I have a huge collection of Instagram videos in different resolutions and with different audio codecs.

    Some videos are 640x640, others are 640x800. You get the picture.

    When I try to concat the videos, the video and audio go out of sync in the final output and the in some places the audio is slowed down(?).

    This is my ffmpeg concat command :

    ffmpeg -i "$(cat /home/list.txt)" -c:v copy -c:a copy /home/output.mp4

    list.txt contains over 800 clips and is formatted correctly :

    file 'clip1.mp4'
    
file 'clip2.mp4'
    
file 'clip3.mp4'
    
etc...

    I believe the issue is due to all the different resolutions and different codecs used, so how can I standardize my collection of clips in order to concat them into a working video file ?
